 # Columns-in-.NET-MAUI-DataGrid
-This sample demonstrate how to generate columns and how to manipulate columns in the .NET MAUI data grid.
+In this article, we’ll guide you through defining, generating, and manipulating columns in the .NET MAUI DataGrid (SfDataGrid). You’ll learn how to declare various column types in XAML, bind data effectively, and programmatically add, edit, remove, or clear columns at runtime. Additionally, we’ll cover techniques for formatting and customizing headers using the AutoGeneratingColumn event. For more details, please refer the official documentation: [Columns in MAUI DataGrid](https://help.syncfusion.com/maui/datagrid/columns).

+## xaml
+```
+    <ContentPage.BindingContext>
+        <local:OrderInfoRepo />
+    </ContentPage.BindingContext>
+
+    <StackLayout>
+
+        <StackLayout Orientation="Horizontal">
+            <Button Text="Add" Clicked="Button_Clicked_1" Margin="3" />
+            <Button Text="Edit" Clicked="Button_Clicked_2" Margin="3" />
+            <Button Text="Remove" Clicked="Button_Clicked_3" Margin="3" />
+            <Button Text="Clear" Clicked="Button_Clicked_4" Margin="3" />
+        </StackLayout>
+
+        <syncfusion:SfDataGrid x:Name="dataGrid" ItemsSource="{Binding Orders}"
+                               ColumnWidthMode="FitByHeader"
+                               AutoGenerateColumnsMode="None" >
+            <syncfusion:SfDataGrid.Columns>
+                <syncfusion:DataGridNumericColumn MappingName="OrderID" HeaderText="Order ID"/>
+                <syncfusion:DataGridTextColumn MappingName="Customer" HeaderText="Customer"/>
+                <syncfusion:DataGridCheckBoxColumn MappingName="IsShipped" HeaderText="Is Shipped"/>
+                <syncfusion:DataGridDateColumn MappingName="ShipTime" HeaderText="Ship Time"/>
+            </syncfusion:SfDataGrid.Columns>
+        </syncfusion:SfDataGrid>
+
+    </StackLayout>
+```
+
+### What this XAML shows
+- Binding to a view model (OrderInfoRepo) that exposes an Orders collection.
+- Disabling auto-generation and declaring explicit columns using Syncfusion types:
+  - DataGridNumericColumn for numeric fields (OrderID)
+  - DataGridTextColumn for strings (Customer)
+  - DataGridCheckBoxColumn for booleans (IsShipped)
+  - DataGridDateColumn for DateTime values (ShipTime)
+- Buttons wired to event handlers for runtime column manipulation.
+
+## C#
+The following code-behind demonstrates how to add a new column, edit a column header, remove a specific column, clear all columns, and customize formatting/headers during auto-generation.
+```
+    private void Button_Clicked_1(object sender, EventArgs e)
+	{
+		var shipCountry = new DataGridTextColumn() { MappingName = "ShipCountry", HeaderText="Ship Country" };
+		this.dataGrid.Columns.Add(shipCountry);
+	}
+
+	private void Button_Clicked_2(object sender, EventArgs e)
+	{
+		var column = this.dataGrid.Columns[0];
+		column.HeaderText = "Client";
+	}
+
+	private void Button_Clicked_3(object sender, EventArgs e)
+	{
+		if (this.dataGrid.Columns.Count > 0)
+			this.dataGrid.Columns.RemoveAt(0);
+	}
+
+	private void Button_Clicked_4(object sender, EventArgs e)
+	{
+		this.dataGrid.Columns.Clear();
+	}
+
+	private void dataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
+	{
+		if(e.Column.MappingName == "ShipTime")
+		{
+			e.Column.Format = "MMM yy";
+		}
+
+		if (e.Column.MappingName == "OrderID")
+			e.Column.HeaderText = "Order ID";
+		else if (e.Column.MappingName == "IsShipped")
+			e.Column.HeaderText = "Is Shipped";
+		else if (e.Column.MappingName == "ShipTime")
+			e.Column.HeaderText = "Ship Time";
+		else if (e.Column.MappingName == "ShipCountry")
+			e.Column.HeaderText = "ShipCountry";
+	}
