CellPointerOver Command

Updated on Mar 26, 2026

The CellPointerOver command handles the PointerOver event over a grid cell. The default implementation will attempt to display the hover UI for either the cell itself or for the owning grid row, depending on the SelectionUnit value.

Execution Parameter

The execution parameter is of type DataGridCellInfo and exposes the following properties:

• Column—Gets the DataGridColumn instance with which the cell is associated.
• Item—Gets the underlying data row (ViewModel instance) with which the cell is associated.

Custom CellPointerOver Command

The following examples show how to create a class that inherits from the DataGridCommand and add it to the Commands collection.

Create a Custom CellPointerOver Command

C#

public class CustomCellPointerOverCommand : DataGridCommand
{
	public CustomCellPointerOverCommand()
	{
		this.Id = CommandId.CellPointerOver;
	}

	public override bool CanExecute(object parameter)
	{
		var context = parameter as DataGridCellInfo;
		// put your custom logic here
		return true;
	}

	public override void Execute(object parameter)
	{
		var context = parameter as DataGridCellInfo;
		// put your custom logic here

		this.Owner.CommandService.ExecuteDefaultCommand(CommandId.CellPointerOver, context);
	}
}

Add the Custom Command to the Commands Collection

XAML

<Grid xmlns:grid="using:Telerik.UI.Xaml.Controls.Grid">
	<grid:RadDataGrid Width="600" Height="460" x:Name="grid" Hold>
		<grid:RadDataGrid.Commands>
			<local:CustomCellPointerOverCommand/>
		</grid:RadDataGrid.Commands>
	</grid:RadDataGrid>
</Grid>
