Bunifu Datagrid View
Optimized theme design for high-performance; Flexible data editing, multiple data binding methods, and data export.
Overview
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
BunifuDatagridView
at Design TimeIt'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
at Run TimeBunifuDataGridView
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.
using System;
using Bunifu.UI.WinForms;
using System.Drawing;
using System.Windows.Forms;
namespace BunifuGrid
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
BunifuDataGridView bunifuDataGridView = new BunifuDataGridView();
bunifuDataGridView.Size = new Size(600, 250);
bunifuDataGridView.Location = new Point(12, 28);
this.Controls.Add(bunifuDataGridView);
bunifuDataGridView.PopulateWithSampleData();
}
}
}
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.

Step two: Create columns on the Datagrid. Here's how to do it in the design view:
a) Select the Datagrid and click on the glyph play icon ( ▶️ ) at the top right position in order to open the Smart Tag.
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

bunifuDataGridView1.CurrentTheme.HeaderStyle.Font = new Font("Segoe UI", 10, FontStyle.Regular);
//set the column header height
bunifuDataGridView1.ColumnHeadersHeight = 36;
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:
private void Form1_Load(object sender, EventArgs e)
{
bunifuDataGridView1.Columns.AddRange(
new DataGridViewTextBoxColumn()
{
HeaderText = "Product ID",
Name = "productIDColumn"
},
new DataGridViewTextBoxColumn()
{
HeaderText = "Product Name",
Name = "productNameColumn"
},
new DataGridViewTextBoxColumn()
{
HeaderText = "Customer Name",
Name = "customerNameColumn"
},
new DataGridViewTextBoxColumn()
{
HeaderText = "Country",
Name = "countryColumn"
},
new DataGridViewTextBoxColumn()
{
HeaderText = "Shipping City",
Name = "shippingCityColumn"
}
);
}
On running the code above, the below output will occur:

The columns can be accessed through its column index or using its Name
property from the bunifuDataGrid.Columns
collection.
DataGridViewColumn dataGridViewColumn = bunifuDataGridView1.Columns[0];
//or
DataGridViewColumn gridViewColumn = 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 column
bunifuDataGridView1.Columns.RemoveAt(1);
//or
bunifuDataGridView1.Columns.Remove(gridViewColumn);
//clear all columns
bunifuDataGridView1.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.:

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.
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:
class Order
{
public string ProductId { get; set; }
public string ProductName { get; set; }
public string CustomerName { get; set; }
public string Country { get; set; }
public string ShippingCity{ get; set; }
}
Step two: In your Form's Load
event write the following code:
using System;
using System.Collections.Generic;
using System.Windows.Forms;
namespace Example2
{
private void Form1_Load(object sender, EventArgs e)
{
List<Order> orderList = new List<Order>()
{
new Order()
{
ProductId = "#01293",
ProductName = "HP Envy x360",
CustomerName = "Dylan Gray",
Country = "Portugal",
ShippingCity = "Spain"
},
new Order()
{
ProductId = "#01294",
ProductName = "Seagate SSDs",
CustomerName = "Sarah Banks",
Country = "United States",
ShippingCity = "New York"
},
new Order()
{
ProductId = "#01295",
ProductName = "HP Envy x360",
CustomerName = "Tracy Rivera",
Country = "Kenya",
ShippingCity = "Nairobi"
}
};
foreach (var order in orderList)
{
bunifuDataGridView1.Rows.Add(order.ProductId,order.ProductName,order.CustomerName,order.Country,order.ShippingCity);
}
}
}
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";
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 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 column
bunifuDataGridView1[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);
}
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.
To retrieve the selected values in a row, refer to the following code:
private void bunifuButton1_Click(object sender, EventArgs e)
{
//get the number of the selected rows
int selectedRows = bunifuDataGridView1.Rows.GetRowCount(DataGridViewElementStates.Selected);
if (selectedRows > 0)
{
StringBuilder cellValuesStringBuilder = new StringBuilder();
//loop through each of the selected row
for(int i = 0; i < selectedRows; i++)
{
//loop the cells of a row, get their values and append them in a string builder
for (int j = 0; j < bunifuDataGridView1.ColumnCount; j++)
{
cellValuesStringBuilder.Append(bunifuDataGridView1.SelectedRows[i].Cells[j].Value+"\t");
}
//create a new line for the next row loop
cellValuesStringBuilder.Append("\n");
}
//print the output on a console
Console.WriteLine(cellValuesStringBuilder);
}
}

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:
private void bunifuButton1_Click(object sender, EventArgs e){
//get the number of selected cells
int selectedCells = bunifuDataGridView1.GetCellCount(DataGridViewElementStates.Selected);
if (selectedCells > 0)
{
StringBuilder cellStrBuilder = new StringBuilder();
//loop through the selected cells, get their values and append to the string builder variable
for(int i = 0; i < selectedCells; i++)
{
cellStrBuilder.Append(bunifuDataGridView1.SelectedCells[i].Value + "\t");
}
//output the seleccted cell values
Console.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 retrieve the selected values in a row, refer to the following code:
private void Form3_Load(object sender, EventArgs e)
{
for (int i = 0; i < bunifuDataGridView1.Columns.Count; i++)
{
//set the sort mode for all the textbox columns
bunifuDataGridView1.Columns(i).SortMode = DataGridViewColumnSortMode.Programmatic;
}
bunifuDataGridView1.SelectionMode = DataGridViewSelectionMode.ColumnHeaderSelect;
}
private void bunifuButton1_Click(object sender, EventArgs e)
{ // get the selected cells in the column
int selectedCells = bunifuDataGridView1.GetCellCount(DataGridViewElementStates.Selected);
StringBuilder strBuider = new StringBuilder();
for (int i = 0; i < selectedCells; i++)
{
//get the selected cell values from the column
strBuider.Append(bunifuDataGridView1.SelectedCells(i).Value + "\t");
}
//output the selected values
Console.WriteLine(strBuider);
}
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 ShowCellTooltips
property. 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 cell
private void bunifuDataGridView1_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 hovered
DataGridViewCell dataGridcell = bunifuDataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
//get the display area or the location of the cell that is currently hovered
var cellreactangle = bunifuDataGridView1.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true);
//check whether the cell has text content in it
if (dataGridcell.Value != null)
{
//use bunifu tooltip to display the text content of the cell
bunifuToolTip1.Show(bunifuDataGridView1, dataGridcell.Value.ToString(), bunifuDataGridView1.Columns[dataGridcell.ColumnIndex].HeaderText, null, bunifuDataGridView1.PointToScreen(new Point(cellreactangle.X + 80, cellreactangle.Y)));
}
}
}
private void bunifuDataGridView1_CellMouseLeave(object sender, DataGridViewCellEventArgs e)
{
bunifuToolTip1.Hide();
}
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
Step 1: Create the following OrderDemo
class with its get and set properties:
class OrderDemo
{
private Guid order_Id=Guid.NewGuid();
public Guid OrderID
{
get { return order_Id; }
set { order_Id = value; }
}
public string ProductName { get; set; }
public string CustomerName { get; set; }
public string PhoneNumber { get; set; }
public string ShippingCity { get; set; }
}
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 bound
BindingSource bindingSource = new BindingSource();
//the form load event containing out BunifuDataGridView
private void Form1_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 = new BindingList<OrderDemo>()
{
//add the class objects to the list, setting their properties
new OrderDemo()
{
CustomerName="Tracy Ravis",
PhoneNumber="(188)1863076",
ShippingCity="Salt Lake City",
ProductName="HP Envy x360 13 (2020)"
},
new OrderDemo()
{
CustomerName="Elsie Harris",
PhoneNumber="(046)1938785",
ShippingCity="Perth",
ProductName="HP Envy 13 (2021)"
},
new OrderDemo()
{
CustomerName="Roger Craig",
PhoneNumber="(042)9830172",
ShippingCity="Australian Capital Territory",
ProductName="HP Spectre x360 14"
},
new OrderDemo()
{
CustomerName="Danny Mckinney",
PhoneNumber="(651)0438562",
ShippingCity="Glendale",
ProductName="HP EliteBook x360 1040 G7"
},
new OrderDemo()
{
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 = bindingSource;
}
Step 3: Run your application. Here's the output of the DataGrid running the codes above code:

2. Binding with a DataTable
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.
class OrderDemo
{
private Guid order_Id=Guid.NewGuid();
public Guid OrderID
{
get { return order_Id; }
set { order_Id = value; }
}
public string ProductName { get; set; }
public string CustomerName { get; set; }
public string PhoneNumber { get; set; }
public string ShippingCity { get; set; }
}
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 void Form5_Load(object sender, EventArgs e)
{
BindingList<OrderDemo> orderDemoList = new BindingList<OrderDemo>()
{
new OrderDemo()
{
CustomerName="Tracy Ravis",
PhoneNumber="(188)1863076",
ShippingCity="Salt Lake City",
ProductName="HP Envy x360 13 (2020)"
},
new OrderDemo()
{
CustomerName="Elsie Harris",
PhoneNumber="(046)1938785",
ShippingCity="Perth",
ProductName="HP Envy 13 (2021)"
},
new OrderDemo()
{
CustomerName="Roger Craig",
PhoneNumber="(042)9830172",
ShippingCity="Australian Capital Territory",
ProductName="HP Spectre x360 14"
},
new OrderDemo()
{
CustomerName="Danny Mckinney",
PhoneNumber="(651)0438562",
ShippingCity="Glendale",
ProductName="HP EliteBook x360 1040 G7"
},
new OrderDemo()
{
CustomerName="Derrick Wade",
PhoneNumber="(636)4728149",
ShippingCity="San Bernardino",
ProductName="HP Chromebook x2"
}
};
}
Secondly, write the following code snippet to create a DataTable and assign columns and rows to it:
DataTable dataTable = new DataTable();
//create an array of table columns
DataColumn[] tableColumns = new DataColumn[]
{
new DataColumn()
{
ColumnName="Order_ID",
DataType=typeof(string),
},
new DataColumn()
{
ColumnName="Product Name",
DataType=typeof(string),
},
new DataColumn()
{
ColumnName="Customer Name",
DataType=typeof(string),
},
new DataColumn()
{
ColumnName="Phone Number",
DataType=typeof(string),
},
new DataColumn()
{
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 values
foreach(var data in orderDemoList)
{
dataTable.Rows.Add(data.OrderID, data.ProductName, data.CustomerName, data.PhoneNumber, data.ShippingCity);
}
//bind the data table to Bunifu DataGridView
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
.
<?xml version="1.0" encoding="utf-8" ?>
<Invoice>
<Item>
<Item_Number>001</Item_Number>
<Item_Name>MacBook Air</Item_Name>
<Item_Price>$999</Item_Price>
</Item>
<Item>
<Item_Number>002</Item_Number>
<Item_Name>MacBook Pro 13</Item_Name>
<Item_Price>$999</Item_Price>
</Item>
<Item>
<Item_Number>003</Item_Number>
<Item_Name>MacBook Pro 16”</Item_Name>
<Item_Price>$999</Item_Price>
</Item>
<Item>
<Item_Number>004</Item_Number>
<Item_Name>Iphone 12 Pro</Item_Name>
<Item_Price>$999</Item_Price>
</Item>
<Item>
<Item_Number>005</Item_Number>
<Item_Name>Iphone 12</Item_Name>
<Item_Price>$699</Item_Price>
</Item>
<Item>
<Item_Number>006</Item_Number>
<Item_Name>Iphone 11</Item_Name>
<Item_Price>$599</Item_Price>
</Item>
</Invoice>
Write the following code in the form load event to read the above XML file and display the data in BunifuDataGridView
:
private void Form6_Load(object sender, EventArgs e)
{
DataSet dataSet = new DataSet();
//get the current directory path
string currentPath = Directory.GetCurrentDirectory();
//get two folders up to the assembly folder
string newPath = Path.GetFullPath(Path.Combine(currentPath, @"..\..\"));
//get the xml file
dataSet.ReadXml(newPath + @"/InvoiceXML.xml");
//bind the xml to Bunifu DataGridView
bunifuDataGridView1.DataSource = dataSet.Tables[0];
}
Here's the output of the above code:

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.

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:
private void Form1_Load(object sender, EventArgs e)
{
//instantiate the entity created from the wizard
BuniEntities buniEntities = 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();
}
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
private void bunifuDataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
//get the cell that has the primary key
int primaryKey= Convert.ToInt32(bunifuDataGridView1.Rows[e.RowIndex].Cells[0].Value);
//get the column name where the cell is currently modified
string columnName = bunifuDataGridView1.Columns[e.ColumnIndex].HeaderText;
//get the cell value modified
string editedValue = bunifuDataGridView1[e.ColumnIndex, e.RowIndex].Value.ToString();
switch (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(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;
}
}
The output of the above code will be as follows:

The following example shows how to retrieve the orders data using an SQL Query and bind the data inBunifuDataGridView
using the form load event:
private void Form6_Load(object sender, EventArgs e)
{
//instantiate the entity created from the wizard
BuniEntities buniEntities = new BuniEntities();
//execute the sql query to retrieve the data
var ordersData= buniEntities.Database.SqlQuery<BunifuData.Order>("Select * From Orders").ToList();
//bind the retrieved data to the datagrid view
bunifuDataGridView1.DataSource = ordersData;
}

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 :
b) Write the following code in the main entry point of your application:
using Micron;
static void Main()
{ //the connection configuration file
MicronConfig connectionConfig = new MicronConfig()
{
Host="localhost",
User="root",
Password="",
Port="8080",
DatabaseName="inventory"
};
MicronDbContext.AddConnectionSetup(connectionConfig);
}
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
BunifuDataGridView
Micron returns IEnumerable<T> interface when retrieving data from a model. Write the following code to select data from the customers table:
private void Form1_Load(object sender, EventArgs e)
{ //create the db context to access data from the database
MicronDbContext dbContext = new MicronDbContext();
//retrieve data from the customer table
var customers = dbContext.GetRecords<Data.Models.Customer>();
//bind the data to Bunifu DataGridView
bunifuDataGridView1.DataSource = customers.Select(x => new {
x.CustomerID,
x.CustomerName,
x.ContactName,
x.City,
x.Country
}).ToList();
}
}
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.
To install and configure Bunifu reports, refer to NuGet Gallery | Bunifu.Reports 1.0.5
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:
private void bunifuButton1_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 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
SaveFileDialog saveFile = new SaveFileDialog();
//add the save file dialog component to the form
this.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)
{
//get the path where the pdf file will be saved
string 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 saved
bunifuReports1.SavePDF(path);
}
}
Here's an output of a pdf generated DatagridView report:
