Bunifu Datagrid View is a feature-rich .NET valuable control for displaying data in a tabular format. It comes with beautiful in-built themes and a vast range of functions: data binding, editing, adding, custom sorting, selecting, and support for PDF formats.
Getting Started
This section provides a quick overview of working with the tabular data for WinForms. We shall walk through the entire process of creating a real-world data grid.
Adding BunifuDatagridView at Design Time
It's easy to add BunifuDatagridView control at design time. Start by locating BunifuDatagridView from your toolbox and drag it to your form as shown below. Then customize it to your desired look and feel using properties elaborated on later in this documentation.
Adding BunifuDataGridView at Run Time
BunifuDataGridView works for both C# and VB.NET. We will use the Form’s Load event to write our sample code to create a BunifuDatagridView and populate the table with built-in sample data.
Imports SystemImports Bunifu.UI.WinFormsImports System.DrawingImports System.Windows.FormsNamespace BunifuGrid Partial Public Class Form1 Inherits Form Public Sub New()InitializeComponent() End Sub Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) Dim bunifuDataGridView As New BunifuDataGridView() bunifuDataGridView.Size = New Size(600,250) bunifuDataGridView.Location = New Point(12,28) Me.Controls.Add(bunifuDataGridView) bunifuDataGridView.PopulateWithSampleData() End Sub End ClassEnd Namespace
Here's the output for the above code:
Creating a simple data entry application (No code!)
Step 1: Create the following form below with the following controls as shown on the labels.
For the DataGridView set the backgroundColor property to a color value of white.
Step two: Create columns on the Datagrid. Here's how to do it in the design view:
b) Click on the Add Column link which opens a dialog that displays Column Collection Editor
c) Add the following columns as shown below
d) Now, run the application, the below output will occur
Let's take a deep dive and get insights into the properties that are available on Bunifu DataGrid View.
Appearance
Bunifu DataGrid View allows you to customize the appearance of your tabular data with ease. Here are the features that you can customize:
1. Built-In Themes
BunifuDataGridView offers 16+ different types of themes that you may utilize in your application. The Theme property allows you to get the property's value or set an enumerated theme value for your tabular data.
BunifuDataGridView exposes an array of properties that can be used to customize the theme. The following is a sampling of the properties related to our chosen theme:
In some cases, you may need to change some of the property values in your current theme. The AllowCustomTheming property allows you to get the property's boolean value or set a boolean value that, when set to true, will enable you to edit the property values that were used to design the theme you selected.

2. Column properties
BunifuDataGridView provides you support for creating and editing both bound and unbound columns with ease. The Below section shows the various properties you can work with to design your column appearance and behavior.
Property name
Description
Columns
This property allows you to get the current collection of columns or set a column collection object containing an array of unbound columns for your tabular data.
The column collection editor is provided in the design view, and it allows you to view, add, update, and delete the existing columns. The columns to be added can be chosen from built-in column types or your own column.
Like the standard DataGridView, the created the unbound column gives you further ability to edit its properties. See how to get more insights on editing the properties provided in the column.
You also can add or edit different types of columns(e.g., Textbox columns, image view columns, e.t.c) using any language you prefer to code with( i.e., the C# and VB.NET languages).
Here's how you can add textbox columns through code:
privatevoidForm1_Load(object sender,EventArgs e){bunifuDataGridView1.Columns.AddRange(newDataGridViewTextBoxColumn() { HeaderText ="Product ID", Name ="productIDColumn" },newDataGridViewTextBoxColumn() { HeaderText ="Product Name", Name ="productNameColumn" },newDataGridViewTextBoxColumn() { HeaderText ="Customer Name", Name ="customerNameColumn" },newDataGridViewTextBoxColumn() { HeaderText ="Country", Name ="countryColumn" },newDataGridViewTextBoxColumn() { HeaderText ="Shipping City", Name ="shippingCityColumn" } );}
Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) bunifuDataGridView1.Columns.AddRange(New DataGridViewTextBoxColumn() With { .HeaderText ="Product ID", .Name ="productIDColumn" }, New DataGridViewTextBoxColumn() With { .HeaderText ="Product Name", .Name ="productNameColumn" }, New DataGridViewTextBoxColumn() With { .HeaderText ="Customer Name", .Name ="customerNameColumn" }, New DataGridViewTextBoxColumn() With { .HeaderText ="Country", .Name ="countryColumn" }, New DataGridViewTextBoxColumn() With { .HeaderText ="Shipping City", .Name ="shippingCityColumn" })End Sub
On running the code above, the below output will occur:
Alternatively, BunifuDataGridView can be bound to a data source, where the columns will be generated automatically. This will be discussed in further detail, later in this documentation.
The columns can be accessed through its column index or using its Name property from the bunifuDataGrid.Columns collection.
Dim dataGridViewColumn As DataGridViewColumn = bunifuDataGridView1.Columns(0)'orDim gridViewColumn As DataGridViewColumn = bunifuDataGridView1.Columns("productIDColumn")
A column can be removed using the Remove and RemoveAt methods. The Clear method removes all columns from bunifuDataGrid.Columns collection.
//remove the second columnbunifuDataGridView1.Columns.RemoveAt(1);//orbunifuDataGridView1.Columns.Remove(gridViewColumn);//clear all columnsbunifuDataGridView1.Columns.Clear();
'remove the second columnbunifuDataGridView1.Columns.RemoveAt(1)'orbunifuDataGridView1.Columns.Remove(gridViewColumn)'clear all columnsbunifuDataGridView1.Columns.Clear()
Property name
Description
ColumnHeadersDefaultCellStyle
This property allows you to get the style object applied in the columns or set a cell style object that contains an array of cell style properties that can change the appearance of the column header row.
Here are the properties that you can edit to the preferred style of your column header row.:
To ensure that the properties are working at runtime, ensure the AllowCustomTheming prop is set to true.
Property
Description
ColumnHeadersHeightSizeMode
This property allows you to get or set the behavior of adjusting the column headers' height during runtime. You can specify the following values: EnableResizing, DisableResizing, and AutoSize.
ColumnHeadersHeight
This property allows you to get or set an integer value that will resize the column header.
ColumnHeadersBorderStyle
This property allows you to get or set the border style applied to the column header.
ColumnHeadersVisible
This property allows you to get or set a boolean value that will hide the column header row when set to false. The default value is true.
3. Row properties
BunifuDataGridView enables you to add, populate, edit or remove rows for both bound and unbound data. Here are the properties you can use to design your rows, populate and edit your rows with ease:
Populating your rows:
It is very easy to populate rows with an unbound data with bunifuDataGridView.Rows collection property.
Rows are only populated at runtime. Also, note that to add the rows, you must have the columns in the first place.
Here's how you can add and populate a row in BunifuDataGridView using C# or VB.NET language. This example assumes that you have added 5 DataGridViewTextBoxColumn instances to BunifuDataGridView control's column collection.
Steps to create the unbound data:
Step one: Create the following class with the get and set properties:
Friend Class Order Public Property ProductId() As String Public Property ProductName() As String Public Property CustomerName() As String Public Property Country() As String Public Property ShippingCity() As StringEnd Class
Step two: In your Form's Load eventwrite the following code:
Option Infer OnImports SystemImports System.Collections.GenericImports System.Windows.FormsNamespace Example2Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) Dim orderList As New List(Of Order)() From { New Order() With { .ProductId="#01293", .ProductName="HP Envy x360", .CustomerName="Dylan Gray", .Country="Portugal", .ShippingCity="Spain" }, New Order() With { .ProductId="#01294", .ProductName="Seagate SSDs", .CustomerName="Sarah Banks", .Country="United States", .ShippingCity="New York" }, New Order() With { .ProductId="#01295", .ProductName="HP Envy x360", .CustomerName="Tracy Rivera", .Country="Kenya", .ShippingCity="Nairobi" } }For Each order In orderList bunifuDataGridView1.Rows.Add(order.ProductId,order.ProductName,order.CustomerName,order.Country,order.ShippingCity)Next orderEnd SubEnd Namespace
Now, after running your application with the codes above, the following output will occur:
You can also use the Rows collection to modify the values in the control or to remove rows. The following example shows you how to modify cell values programmatically.
//Modify the value in the second cell of the third row.bunifuDataGridView1.Rows[2].Cells[1].Value="Dell AlienWare M17 R4";// The previous line is equivalent to the following line. bunifuDataGridView1[1,2].Value="Dell AlienWare M17 R4";
'Modify the value in the second cell of the third row.bunifuDataGridView1.Rows(2).Cells(1).Value = "Dell AlienWare M17 R4"' The previous line is equivalent to the following line. bunifuDataGridView1(1,2).Value="Dell AlienWare M17 R4"
Styling a row cell
The appearance of a BunifuDataGrid cell can be customized using the bunifuDataGridView.Rows collection Style property. We have the option to style the back color, its selection color, the font, its forecolor, and the alignment of text in a particular cell.
The following example shows you how to style the appearance of a cell back color programmatically. The assumption is that you already have some data in your table.
for(int i =0; i <bunifuDataGridView1.Rows.Count; i++){ //Modify the backcolor, the fore color and selection color in every cell of the FIRST columnbunifuDataGridView1[1, i].Style.BackColor=Color.FromArgb(152,175,92);bunifuDataGridView1[1, i].Style.ForeColor=Color.White;bunifuDataGridView1[1, i].Style.SelectionBackColor=Color.FromArgb(63,137,90); //Modify the backcolor, the fore color and selection color every cell of the THIRD columnbunifuDataGridView1[4, i].Style.BackColor=Color.FromArgb(152,175,92);bunifuDataGridView1[4, i].Style.ForeColor=Color.White;bunifuDataGridView1[4, i].Style.SelectionBackColor=Color.FromArgb(63,137,90);}
For i As Integer =0 To bunifuDataGridView1.Rows.Count -1 'Modify the backcolor, the fore color and selection color in every cell of the FIRST column bunifuDataGridView1(1, i).Style.BackColor = Color.FromArgb(152, 175, 92) bunifuDataGridView1(1, i).Style.ForeColor = Color.White bunifuDataGridView1(1, i).Style.SelectionBackColor = Color.FromArgb(63, 137, 90) 'Modify the backcolor, the fore color and selection color every cell of the THIRD columnbunifuDataGridView1(4, i).Style.BackColor = Color.FromArgb(152,175,92)bunifuDataGridView1(4, i).Style.ForeColor = Color.WhitebunifuDataGridView1(4, i).Style.SelectionBackColor = Color.FromArgb(63,137,90)Next i
The above code will output the occurrence below:
4. Selection
BunifuDataGrid enables you to select a single row or cell or multiple rows or cells. Sometimes you want your application to perform actions such as printing out the selected rows or columns based on user selections within the tabular control. Depending on the actions, you may want to restrict the kinds of selection that are possible.
This section will explain the types of selection available for GridControl and its usability.
a) Row selection
You can specify a full row type of selection by setting the BunifuDataGridView.SelectionMode property to FullRowSelect.
When a cell or row header is clicked in the DataGrid, an entire row selection is created.
By default, users can select multiple rows, columns, or cells by dragging with the mouse, pressing CTRL or SHIFT keys while selecting to extend or modify a selection. To prevent this behavior set the MultiSelect property to false.
To retrieve the selected values in a row, refer to the following code:
privatevoidbunifuButton1_Click(object sender,EventArgs e){ //get the number of the selected rowsint selectedRows =bunifuDataGridView1.Rows.GetRowCount(DataGridViewElementStates.Selected);if (selectedRows >0) {StringBuilder cellValuesStringBuilder =newStringBuilder(); //loop through each of the selected rowfor(int i =0; i < selectedRows; i++) { //loop the cells of a row, get their values and append them in a string builderfor (int j =0; j <bunifuDataGridView1.ColumnCount; j++) {cellValuesStringBuilder.Append(bunifuDataGridView1.SelectedRows[i].Cells[j].Value+"\t"); } //create a new line for the next row loopcellValuesStringBuilder.Append("\n"); } //print the output on a consoleConsole.WriteLine(cellValuesStringBuilder); }}
Private Sub bunifuButton1_Click(ByVal sender As Object, ByVal e As EventArgs) 'get the number of the selected rows Dim selectedRows As Integer = bunifuDataGridView1.Rows.GetRowCount(DataGridViewElementStates.Selected) If selectedRows > 0 Then Dim cellValuesStringBuilder As New StringBuilder() 'loop through each of the selected row For i As Integer =0 To selectedRows -1 'loop the cells of a row, get their values and append them in a string builder For j As Integer = 0 To bunifuDataGridView1.ColumnCount - 1 cellValuesStringBuilder.Append(bunifuDataGridView1.SelectedRows(i).Cells(j).Value & vbTab) Next j 'create a new line for the next row loop cellValuesStringBuilder.Append(vbLf) Next i 'print the output on a console Console.WriteLine(cellValuesStringBuilder) End IfEnd Sub
The selected values are printed in the output screen as follows:
b) Cell selection
A cell selection is specified by setting BunifuDataGridView.Selection property to CellSelect. When a user clicks on a cell, a selection is created on that cell.
The following image shows for multiple mode cell selection:
Here's a code that retrieves the selected cell values:
privatevoidbunifuButton1_Click(object sender,EventArgs e){//get the number of selected cellsint selectedCells =bunifuDataGridView1.GetCellCount(DataGridViewElementStates.Selected);if (selectedCells >0){StringBuilder cellStrBuilder =newStringBuilder(); //loop through the selected cells, get their values and append to the string builder variablefor(int i =0; i < selectedCells; i++) {cellStrBuilder.Append(bunifuDataGridView1.SelectedCells[i].Value+"\t"); } //output the seleccted cell valuesConsole.WriteLine(cellStrBuilder);}
The selected values are printed in the output screen as follows:
c) Header column selection
BunifuDataGridView allows you to select or deselect rows within a specific column by interacting with the column's header cell. To set this type of selection set the SelectionMode prop to ColumnHeaderSelect.
To make this type of selection work, ensure that the SortMode property for the textbox columns is set to programmatic. The sorting techniques will be discussed in greater detail later in this documentation.
To retrieve the selected values in a row, refer to the following code:
privatevoidForm3_Load(object sender,EventArgs e){for (int i =0; i <bunifuDataGridView1.Columns.Count; i++) { //set the sort mode for all the textbox columnsbunifuDataGridView1.Columns(i).SortMode=DataGridViewColumnSortMode.Programmatic; }bunifuDataGridView1.SelectionMode=DataGridViewSelectionMode.ColumnHeaderSelect;}privatevoidbunifuButton1_Click(object sender,EventArgs e){ // get the selected cells in the columnint selectedCells =bunifuDataGridView1.GetCellCount(DataGridViewElementStates.Selected);StringBuilder strBuider =newStringBuilder();for (int i =0; i < selectedCells; i++) { //get the selected cell values from the columnstrBuider.Append(bunifuDataGridView1.SelectedCells(i).Value+"\t"); } //output the selected valuesConsole.WriteLine(strBuider);}
Imports Microsoft.VisualBasicPrivate Sub Form3_Load(ByVal sender As Object, ByVal e As EventArgs) For i As Integer =0 To bunifuDataGridView1.Columns.Count -1 bunifuDataGridView1.Columns(i).SortMode = DataGridViewColumnSortMode.Programmatic Next i bunifuDataGridView1.SelectionMode = DataGridViewSelectionMode.ColumnHeaderSelectEnd SubPrivate Sub bunifuButton1_Click(ByVal sender As Object, ByVal e As EventArgs) Dim selectedCells As Integer = bunifuDataGridView1.GetCellCount(DataGridViewElementStates.Selected) Dim strBuider As New StringBuilder() For i As Integer =0 To selectedCells -1 strBuider.Append(bunifuDataGridView1.SelectedCells(i).Value & vbTab) Next i Console.WriteLine(strBuider)End Sub
d) Disable selection
The selection can be disabled by setting the Enabled property to False.
When the Datagrid control is disabled, it becomes a read-only control.
5. Custom Tooltips
There are instances where Datagrid cells contain extensive text content, and this information is hidden due to the cell's size. As a result, ToolTips are added to provide support for displaying the entire text content in a pop-up window that appears when the mouse hovers over the cells of a BunifuDataGrid.
The steps below demonstrate how we will override the standard DataGrid tooltip and replace it with a more customizable Bunifu tooltip control. It is assumed that you already have a Datagrid with data in its cells.
Step one: Drag and drop a Bunifu Tooltip control in the form.
Step two: Access the properties of BunifuDataGrid and look out for the ShowCellTooltipsproperty. Set it to false. This will enable us to add our own custom tooltip.
Step three: Go to the event properties of BunifuDataGrid and look out for the CellMouseEnter event. Double-click on its text area to navigate to the code view.
Step four: Write the following code:
//the event gets fired when the mouse is over the cellprivatevoidbunifuDataGridView1_CellMouseEnter(object sender,DataGridViewCellEventArgs e){/* * check whether the mouse is over the row cells of the datagrid. * this avoids the code below from executing when the mouse hovers on the column header cells and row header cells */if(e.ColumnIndex>=0&e.RowIndex>=0) { //get the row datagrid cell currently hoveredDataGridViewCell dataGridcell =bunifuDataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex]; //get the display area or the location of the cell that is currently hoveredvar cellreactangle =bunifuDataGridView1.GetCellDisplayRectangle(e.ColumnIndex,e.RowIndex,true); //check whether the cell has text content in itif (dataGridcell.Value!=null) { //use bunifu tooltip to display the text content of the cellbunifuToolTip1.Show(bunifuDataGridView1,dataGridcell.Value.ToString(),bunifuDataGridView1.Columns[dataGridcell.ColumnIndex].HeaderText,null,bunifuDataGridView1.PointToScreen(newPoint(cellreactangle.X+80,cellreactangle.Y))); } } }privatevoidbunifuDataGridView1_CellMouseLeave(object sender,DataGridViewCellEventArgs e){bunifuToolTip1.Hide();}
Option Infer On'the event gets fired when the mouse is over the cellPrivate Sub bunifuDataGridView1_CellMouseEnter(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs)' ' * check whether the mouse is over the row cells of the datagrid.' * this avoids the code below from executing when the mouse hovers on the column header cells and row header cells' If e.ColumnIndex >= 0 And e.RowIndex >= 0 Then 'get the row datagrid cell currently hovered Dim dataGridcell As DataGridViewCell = bunifuDataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex) 'get the display area or the location of the cell that is currently hovered Dim cellreactangle = bunifuDataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, True) 'check whether the cell has text content in it If dataGridcell.Value IsNot Nothing Then 'use bunifu tooltip to display the text content of the cell bunifuToolTip1.Show(bunifuDataGridView1, dataGridcell.Value.ToString(), "08/07/2021", Nothing, bunifuDataGridView1.PointToScreen(New Point(cellreactangle.X + 80, cellreactangle.Y))) End If End IfEnd SubPrivate Sub bunifuDataGridView1_CellMouseLeave(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs) bunifuToolTip1.Hide()End Sub
Step 5: Run your application. Here's is an example of our application running the codes above, the following output will occur:
Data Binding
BunifuDataGrid has been designed to support the use of bounded data.
Let us examine each feature in detail to ensure that we are maximizing the use of bounded data properties, methods, and events to the fullest extent possible.
Bunifu DataGrid View has data-binding support to work out-of-the-box with all popular data sources like SQL Server, Oracle, DataTable, and IEnumerable, and data providers like LINQ to SQL, ADO.NET, Entity Framework, and WCF Data Service.
If the data source implements the INotifyCollectionChanged interface, then BunifuDataGridView will automatically refresh the UI when an item is added, removed, or while the list cleared.
1. Binding to a Generic Collection List
It's simple and clear to create a generic collection with binding properties, which results in bounded data. The following code illustrates how we can bind a collection of list objects with the BindingList Class to create tabular data for BunifuDataGridView
Note that the column header names will be created automatically based on the property names given to the class objects.
Step 1: Create the following OrderDemo class with its get and set properties:
Public Class DemoOrder Private order_Id As Guid=Guid.NewGuid() Public Property OrderID() As Guid Get Return order_Id End GetSet(ByVal value As Guid) order_Id = value End Set End Property Public Property ProductName() As String Public Property CustomerName() As String Public Property PhoneNumber() As String Public Property ShippingCity() As StringEnd Class
Step 2: In the form load event of your form write the following code:
//the global variable provides the source of data for the Datagrid and where the generic list will be boundBindingSource bindingSource =newBindingSource();//the form load event containing out BunifuDataGridViewprivatevoidForm1_Load(object sender,EventArgs e){/* *the BindingList class is of type OrderDemo *has support to provide binding capabilities for a generic list */BindingList<OrderDemo> orderDemoList =newBindingList<OrderDemo>() { //add the class objects to the list, setting their propertiesnewOrderDemo() { CustomerName="Tracy Ravis", PhoneNumber="(188)1863076", ShippingCity="Salt Lake City", ProductName="HP Envy x360 13 (2020)" },newOrderDemo() { CustomerName="Elsie Harris", PhoneNumber="(046)1938785", ShippingCity="Perth", ProductName="HP Envy 13 (2021)" },newOrderDemo() { CustomerName="Roger Craig", PhoneNumber="(042)9830172", ShippingCity="Australian Capital Territory", ProductName="HP Spectre x360 14" },newOrderDemo() { CustomerName="Danny Mckinney", PhoneNumber="(651)0438562", ShippingCity="Glendale", ProductName="HP EliteBook x360 1040 G7" },newOrderDemo() { CustomerName="Derrick Wade", PhoneNumber="(636)4728149", ShippingCity="San Bernardino", ProductName="HP Chromebook x2" } }; //bind the list to the binding sourcebindingSource.DataSource= orderDemoList; //set the binding source as the data source for Bunifu DataGrid ViewbunifuDataGridView1.DataSource= bindingSource;}
'the global variable provides the source of data for the Datagrid and where the generic list will be boundPrivate bindingSource As New BindingSource()'the form load event containing out BunifuDataGridViewPrivate Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)' ' *the BindingList class is of type OrderDemo' *has support to provide binding capabilities for a generic list' Dim orderDemoList As New BindingList(Of OrderDemo)() From { New OrderDemo() With { .CustomerName="Tracy Ravis", .PhoneNumber="(188)1863076", .ShippingCity="Salt Lake City", .ProductName="HP Envy x360 13 (2020)" }, New OrderDemo() With { .CustomerName="Elsie Harris", .PhoneNumber="(046)1938785", .ShippingCity="Perth", .ProductName="HP Envy 13 (2021)" }, New OrderDemo() With { .CustomerName="Roger Craig", .PhoneNumber="(042)9830172", .ShippingCity="Australian Capital Territory", .ProductName="HP Spectre x360 14" }, New OrderDemo() With { .CustomerName="Danny Mckinney", .PhoneNumber="(651)0438562", .ShippingCity="Glendale", .ProductName="HP EliteBook x360 1040 G7" }, New OrderDemo() With { .CustomerName="Derrick Wade", .PhoneNumber="(636)4728149", .ShippingCity="San Bernardino", .ProductName="HP Chromebook x2" } } 'bind the list to the binding source bindingSource.DataSource = orderDemoList 'set the binding source as the data source for Bunifu DataGrid View bunifuDataGridView1.DataSource = bindingSourceEnd Sub
Step 3: Run your application. Here's the output of the DataGrid running the codes above code:
2. Binding with a DataTable
Binding with a DataTable is quite easy withBunifuDataGridView. Once your DataTable is set with the rows and columns, you just need to assign it to the DataSource property of BunifuDataGridView. The DataGrid control automatically refreshes the UI when rows are added, removed, or cleared in the DataTable. Here's a code to bind the DataTable to BunifuDataGridView.
Step 1: Create the class with the get and set properties. We will use it and create a list of this class type to hold our table values.
Public Class DemoOrder Private order_Id As Guid=Guid.NewGuid() Public Property OrderID() As Guid Get Return order_Id End GetSet(ByVal value As Guid) order_Id = value End Set End Property Public Property ProductName() As String Public Property CustomerName() As String Public Property PhoneNumber() As String Public Property ShippingCity() As StringEnd Class
Step 2: In the Form load event, we will create the DataTable and assign it as a data source for BunifuDataGridView. Firstly write the following code to add the Order objects in a list:
Private Sub Form5_Load(ByVal sender As Object, ByVal e As EventArgs) Dim orderDemoList As New BindingList(Of OrderDemo)() From { New OrderDemo() With { .CustomerName="Tracy Ravis", .PhoneNumber="(188)1863076", .ShippingCity="Salt Lake City", .ProductName="HP Envy x360 13 (2020)" }, New OrderDemo() With { .CustomerName="Elsie Harris", .PhoneNumber="(046)1938785", .ShippingCity="Perth", .ProductName="HP Envy 13 (2021)" }, New OrderDemo() With { .CustomerName="Roger Craig", .PhoneNumber="(042)9830172", .ShippingCity="Australian Capital Territory", .ProductName="HP Spectre x360 14" }, New OrderDemo() With { .CustomerName="Danny Mckinney", .PhoneNumber="(651)0438562", .ShippingCity="Glendale", .ProductName="HP EliteBook x360 1040 G7" }, New OrderDemo() With { .CustomerName="Derrick Wade", .PhoneNumber="(636)4728149", .ShippingCity="San Bernardino", .ProductName="HP Chromebook x2" } }End Sub
Secondly, write the following code snippet to create a DataTable and assign columns and rows to it:
DataTable dataTable =newDataTable();//create an array of table columnsDataColumn[] tableColumns =newDataColumn[]{newDataColumn() { ColumnName="Order_ID", DataType=typeof(string), },newDataColumn() { ColumnName="Product Name", DataType=typeof(string), },newDataColumn() { ColumnName="Customer Name", DataType=typeof(string), },newDataColumn() { ColumnName="Phone Number", DataType=typeof(string), },newDataColumn() { ColumnName="Shipping City", DataType=typeof(string), }}; dataTable.Columns.AddRange(tableColumns);//loop through the each of the order objects in the list and get their prop valuesforeach(var data in orderDemoList){dataTable.Rows.Add(data.OrderID,data.ProductName,data.CustomerName,data.PhoneNumber,data.ShippingCity);}//bind the data table to Bunifu DataGridViewbunifuDataGridView1.DataSource= dataTable;
Option Infer On
Dim dataTable As New DataTable()
'create an array of table columns
Dim tableColumns() As DataColumn = {
New DataColumn() With {
.ColumnName="Order_ID",
.DataType=GetType(String)
},
New DataColumn() With {
.ColumnName="Product Name",
.DataType=GetType(String)
},
New DataColumn() With {
.ColumnName="Customer Name",
.DataType=GetType(String)
},
New DataColumn() With {
.ColumnName="Phone Number",
.DataType=GetType(String)
},
New DataColumn() With {
.ColumnName="Shipping City",
.DataType=GetType(String)
}
}
dataTable.Columns.AddRange(tableColumns)
'loop through the each of the order objects in the list and get their prop values
For Each data In orderDemoList
dataTable.Rows.Add(data.OrderID, data.ProductName, data.CustomerName, data.PhoneNumber, data.ShippingCity)
Next data
bunifuDataGridView1.DataSource = dataTable
Here's the output upon running the codes above:
3. Binding to XML Data
We can load data easily from an XML file toBunifuDataGridView. This can be achieved by using the DataSet object which provides the necessary methods that are used to read XML data into the dataset.
To generate an XML file, right-click the project's name in the solution explorer tab and select the add option. In the pop-up window displayed navigate to the Data tab and select the XML File item.
The following is an example of XML Data that we will bind to BunifuDataGridView.
Write the following code in the form load event to read the above XML file and display the data in BunifuDataGridView:
privatevoidForm6_Load(object sender,EventArgs e){DataSet dataSet =newDataSet(); //get the current directory pathstring currentPath =Directory.GetCurrentDirectory(); //get two folders up to the assembly folderstring newPath =Path.GetFullPath(Path.Combine(currentPath,@"..\..\")); //get the xml filedataSet.ReadXml(newPath +@"/InvoiceXML.xml"); //bind the xml to Bunifu DataGridViewbunifuDataGridView1.DataSource=dataSet.Tables[0];}
Private Sub Form6_Load(ByVal sender As Object, ByVal e As EventArgs) Dim dataSet As New DataSet() 'get the current directory path Dim currentPath As String = Directory.GetCurrentDirectory() 'get two folders up to the assembly folder Dim newPath As String = Path.GetFullPath(Path.Combine(currentPath,"..\..\")) 'get the xml file dataSet.ReadXml(newPath & "/InvoiceXML.xml") bunifuDataGridView1.DataSource = dataSet.Tables(0)End Sub
Here's the output of the above code:
It is also possible to save the changes back to the XML file.
4. Binding Data from ADO.NET Framework Entity
BunifuDataGridView provides the support to bind data from an ADO.NET Entity Framework. The ADO.NET entity framework is a database access technology that contains object-oriented classes to create high performance when accessing any kind of data source.
ADO .NET uses SQL queries and stored procedures to read write update and delete data from a data source. This walk-through describes binding data from ADO.NET Entity Framework and saving back the changes to the database.
Step 1: Create a data model using the entity framework.
To create the data model:
a) Right-click the project's name in the solution explorer, select the Add option, then click on New Item.
b) In the pop-up wizard displayed, select the Data node, then select the ADO.NET Entity Data Mode item and click the add button.
c) Next, on the wizard displayed as shown below, select the EF Designer from database option and then click Next.
d) In the Choose Your Data Connection wizard, click the new connection button, select Microsoft SQL SERVER as the data source and click the continue button. To configure/modify connection, refer: How to: Create Connections to SQL Server Databases.
This section assumes that you already have a database in your SQL Server. It is important to ensure that you have installed the Microsoft SQL Express Server and its management studio.
Click the OK button after successfully testing the connection.
e) In the choose your data connection Click the Next button . Ensure that you have a connection string displayed on the window and you have enabled/checked the save connection setting option.
f) In the next window select Entity version 6.x as the version entity framework to use, then click the next button.
g) Select the tables that you want to include in your entity model and click the on the finish button.
Once it has finished creating the model, the following diagram will appear as follows in your visual studio:
Step 2: Loading data from the model to BunifuDataGridView:
To bind the data from the entity model, write the following code in the form load event:
privatevoidForm1_Load(object sender,EventArgs e){ //instantiate the entity created from the wizardBuniEntities buniEntities =newBuniEntities(); //load the table data from the databasebuniEntities.Orders.Load();//use System.Data.Entity for the load method //bind the data to Bunifu DataGridView/*the local property provides access to the data * without a query being sent to the database */bunifuDataGridView1.DataSource=buniEntities.Orders.Local.ToBindingList();}
Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) 'instantiate the entity created from the wizard Dim buniEntities As New BuniEntities() 'load the table data from the database buniEntities.Orders.Load() 'use System.Data.Entity for the load method 'bind the data to Bunifu DataGridView' the local property provides access to the data ' * without a query being sent to the database' bunifuDataGridView1.DataSource = buniEntities.Orders.Local.ToBindingList()End Sub
The following is the output of the above code where the data has been loaded from the database:
To update a cell value and reflect the changes in the database, write the following code in the cellEndEdit event of BunifuDataGridView
privatevoidbunifuDataGridView1_CellEndEdit(object sender,DataGridViewCellEventArgs e){ //get the cell that has the primary keyint primaryKey=Convert.ToInt32(bunifuDataGridView1.Rows[e.RowIndex].Cells[0].Value); //get the column name where the cell is currently modifiedstring columnName =bunifuDataGridView1.Columns[e.ColumnIndex].HeaderText; //get the cell value modifiedstring editedValue =bunifuDataGridView1[e.ColumnIndex,e.RowIndex].Value.ToString();switch (columnName) {case"ProductName": //update the entity model object with a new valuebuniEntities.Orders.Find(primaryKey).ProductName= editedValue; //save the changes in the databasebuniEntities.SaveChanges();bunifuSnackbar1.Show(this,"Changes effected on one row",BunifuSnackbar.MessageTypes.Information,1200,null,BunifuSnackbar.Positions.MiddleCenter);break;case"CustomerName":buniEntities.Orders.Find(primaryKey).CustomerName= editedValue;buniEntities.SaveChanges();bunifuSnackbar1.Show(this,"Changes effected on one row",BunifuSnackbar.MessageTypes.Information,1200,null,BunifuSnackbar.Positions.MiddleCenter);break;case"ShippingCity":buniEntities.Orders.Find(primaryKey).ShippingCity= editedValue;bunifuSnackbar1.Show(this,"Changes effected on one row",BunifuSnackbar.MessageTypes.Information,1200,null,BunifuSnackbar.Positions.MiddleCenter);buniEntities.SaveChanges();break;case"State":buniEntities.Orders.Find(primaryKey).State= editedValue;buniEntities.SaveChanges();break;case"Quantity":buniEntities.Orders.Find(primaryKey).Quantity=Convert.ToInt32(editedValue);bunifuSnackbar1.Show(this,"Changes effected on one row",BunifuSnackbar.MessageTypes.Information,1200,null,BunifuSnackbar.Positions.MiddleCenter);buniEntities.SaveChanges();break;case"UnitPrice":buniEntities.Orders.Find(primaryKey).UnitPrice=Convert.ToInt32(editedValue);buniEntities.SaveChanges();bunifuSnackbar1.Show(this,"Changes effected on one row",BunifuSnackbar.MessageTypes.Information,1200,null,BunifuSnackbar.Positions.MiddleCenter);break;default:break; }}
Private Sub bunifuDataGridView1_CellEndEdit(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs) 'get the cell that has the primary key Dim primaryKey As Integer= Convert.ToInt32(bunifuDataGridView1.Rows(e.RowIndex).Cells(0).Value) 'get the column name where the cell is currently modified Dim columnName As String = bunifuDataGridView1.Columns(e.ColumnIndex).HeaderText 'get the cell value modified Dim editedValue As String = bunifuDataGridView1(e.ColumnIndex, e.RowIndex).Value.ToString() Select Case columnName Case "ProductName" 'update the entity model object with a new value buniEntities.Orders.Find(primaryKey).ProductName = editedValue 'save the changes in the database buniEntities.SaveChanges() bunifuSnackbar1.Show(Me, "Changes effected on one row", BunifuSnackbar.MessageTypes.Information, 1200, Nothing, BunifuSnackbar.Positions.MiddleCenter) Case "CustomerName" buniEntities.Orders.Find(primaryKey).CustomerName = editedValue buniEntities.SaveChanges() bunifuSnackbar1.Show(Me, "Changes effected on one row", BunifuSnackbar.MessageTypes.Information, 1200, Nothing, BunifuSnackbar.Positions.MiddleCenter) Case "ShippingCity" buniEntities.Orders.Find(primaryKey).ShippingCity = editedValue bunifuSnackbar1.Show(Me, "Changes effected on one row", BunifuSnackbar.MessageTypes.Information, 1200, Nothing, BunifuSnackbar.Positions.MiddleCenter) buniEntities.SaveChanges() Case "State" buniEntities.Orders.Find(primaryKey).State = editedValue buniEntities.SaveChanges() Case "Quantity" buniEntities.Orders.Find(primaryKey).Quantity = Convert.ToInt32(editedValue) bunifuSnackbar1.Show(Me, "Changes effected on one row", BunifuSnackbar.MessageTypes.Information, 1200, Nothing, BunifuSnackbar.Positions.MiddleCenter) buniEntities.SaveChanges() Case "UnitPrice" buniEntities.Orders.Find(primaryKey).UnitPrice = Convert.ToInt32(editedValue) buniEntities.SaveChanges() bunifuSnackbar1.Show(Me, "Changes effected on one row", BunifuSnackbar.MessageTypes.Information, 1200, Nothing, BunifuSnackbar.Positions.MiddleCenter) Case Else End SelectEnd Sub
The output of the above code will be as follows:
You can use SQL Queries and Linq to update, create, read and update data in the ADO.NET Entity Framework
The following example shows how to retrieve the orders data using an SQL Query and bind the data inBunifuDataGridView using the form load event:
privatevoidForm6_Load(object sender,EventArgs e) { //instantiate the entity created from the wizardBuniEntities buniEntities =newBuniEntities(); //execute the sql query to retrieve the datavar ordersData=buniEntities.Database.SqlQuery<BunifuData.Order>("Select * From Orders").ToList(); //bind the retrieved data to the datagrid viewbunifuDataGridView1.DataSource= ordersData; }
Option Infer OnPrivate Sub Form6_Load(ByVal sender As Object, ByVal e As EventArgs) 'instantiate the entity created from the wizard Dim buniEntities As New BuniEntities() 'execute the sql query to retrieve the data Dim ordersData= buniEntities.Database.SqlQuery(Of BunifuData.Order)("Select * From Orders").ToList() 'bind the retrieved data to the datagrid view bunifuDataGridView1.DataSource = ordersDataEnd Sub
5. Binding Data from MySQL Database (Using Micron)
The Micron library allows us to easily query data from both MySQL and MariaDB database engines. It automatically creates models that match your database schema. To install and configure the Micron library, refer: How to install the Micron ORM library.
Below is the walk-through that describes binding data from the MySQL database using the Micron ORM Framework and saving back the changes to the database.
Step 1: Connecting to MySQL Database:
To connect to a MySQL database :
First, download the demo database file below and import it in your MySQL database.
b) Write the following code in the main entry point of your application:
Imports MicronShared Sub Main() 'the connection configuration file Dim connectionConfig As New MicronConfig() With { .Host="localhost", .User="root", .Password="", .Port="8080", .DatabaseName="inventory" } MicronDbContext.AddConnectionSetup(connectionConfig)End Sub
c) Open Nuget Package Manager Console and execute command below:
update-micron database-first
This tests the connection set above and on a successful connection it creates the models matching the database schema
The following folder will be created with the models from the database tables:
Step 2: Loading data from the customers model to BunifuDataGridView
Micron returns IEnumerable<T> interfacewhen retrieving data from a model. Write the following code to select data from the customers table:
privatevoidForm1_Load(object sender,EventArgs e){ //create the db context to access data from the database MicronDbContext dbContext =newMicronDbContext(); //retrieve data from the customer tablevar customers =dbContext.GetRecords<Data.Models.Customer>(); //bind the data to Bunifu DataGridViewbunifuDataGridView1.DataSource=customers.Select(x =>new {x.CustomerID,x.CustomerName,x.ContactName,x.City,x.Country }).ToList();}}
Option Infer OnPrivate Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) 'create the db context to access data from the database Dim dbContext As New MicronDbContext() 'retrieve data from the customer table Dim customers = dbContext.GetRecords(Of Data.Models.Customer)() 'bind the data to Bunifu DataGridView bunifuDataGridView1.DataSource = customers.Select(Function(x) New With { Key x.CustomerID, Key x.CustomerName, Key x.ContactName, Key x.City, Key x.Country }).ToList()End Sub}
The above code outputs the following MySQL data in the Datagrid:
Data virtualization
BunifuDataGridView provides support to handle a large amount of data through built-in virtualization features.
With Data virtualization, there is the processing of the data in on-demand for better performance while loading a large amount of data. A large amount of data can be loaded in less time by setting VirtualMode property to true.
Exporting Data to PDF(using Bunifu Reports)
Bunifu reports is a special kind of reporting tool that can be integrated seamlessly into your visual studio project. It allows you as a developer to add the reporting module that can generate pdf content from any .NET control that conveys data to the user.
Below is the walk-through that describes how to export BunifuDatagridView content to a PDF file using Bunifu reports:
Step one: In the design view, drag and drop a Bunifu report component from the toolbox to your form.
Step two: Have your BunifuDatagridView populated with ready data from any data source.
Step three: Create a save button in your form and double click it to navigate to the code view.
Step four: Write the following code in the click event of the button:
privatevoidbunifuButton1_Click(object sender,EventArgs e) {/*add a label control from the form * this will take all the property styles used in the label * and apply them in the report */bunifuReports1.AddControl(titleBunifuLabel); //add some line breaks to create a space before rendering the next controlbunifuReports1.AddLineBreak();bunifuReports1.AddLineBreak();/* * add Bunifu DataGridView control to the form * with the use of the AddDataGridView method * the first parameter is the Datagrid control * while the second parameter is the customization of the control rendered * in the report */bunifuReports1.AddDatagridView(bunifuDataGridView1,"border=0;"); //instantiate the save file dialog class to save the report as a pdfSaveFileDialog saveFile =newSaveFileDialog(); //add the save file dialog component to the formthis.components.Add(saveFile); //add a save as file type filtersaveFile.Filter="PDF(*.pdf)|*.pdf"; //display the dialog and execute the code below when the ok button is pressedif(saveFile.ShowDialog() ==DialogResult.OK) { //get the path where the pdf file will be savedstring path =Path.GetFullPath(saveFile.FileName); //use the SavePDF method of Bunifu reports component to save the file //inside the method we shall pass the path where the pdf will be savedbunifuReports1.SavePDF(path); }}
Private Sub bunifuButton1_Click(ByVal sender As Object, ByVal e As EventArgs)' add a label control from the form' * this will take all the property styles used in the label' * and apply them in the report' bunifuReports1.AddControl(titleBunifuLabel) 'add some line breaks to create a space before rendering the next control bunifuReports1.AddLineBreak() bunifuReports1.AddLineBreak()' ' * add Bunifu DataGridView control to the form' * with the use of the AddDataGridView method' * the first parameter is the Datagrid control' * while the second parameter is the customization of the control rendered ' * in the report' bunifuReports1.AddDatagridView(bunifuDataGridView1,"border=0;") 'instantiate the save file dialog class to save the report as a pdf Dim saveFile As New SaveFileDialog() 'add the save file dialog component to the form Me.components.Add(saveFile) 'add a save as file type filter saveFile.Filter = "PDF(*.pdf)|*.pdf" 'display the dialog and execute the code below when the ok button is pressed If saveFile.ShowDialog()= DialogResult.OK Then 'get the path where the pdf file will be saved Dim path As String = System.IO.Path.GetFullPath(saveFile.FileName) 'use the SavePDF method of Bunifu reports component to save the file 'inside the method we shall pass the path where the pdf will be saved bunifuReports1.SavePDF(path) End If End Sub
Here's an output of a pdf generated DatagridView report:
