CellFlyoutAction Command

Updated on Mar 26, 2026

The CellFlyoutAction command handles the contents and the appearance of a grid cell when a cell flyout is initiated either through hover or hold. The default implementation will open а flyout displaying the cell contents.

Execution Parameter

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

• CellInfo—Gets the DataGridCellInfo instance with which the cell is associated, providing access to its column and data item.
• FlyoutTemplate—Gets or sets the DataTemplate that can be used instead of default cell template to display cell content.
• IsOpen—Gets or sets whether the flyout is open.

Custom CellFlyoutAction 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 CellFlyoutAction Command

C#

public class CustomCellFlyoutActionCommand : DataGridCommand
{
	public CustomCellFlyoutActionCommand()
	{
		this.Id = CommandId.CellFlyoutAction;
	}

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

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

		this.Owner.CommandService.ExecuteDefaultCommand(CommandId.CellFlyoutAction, 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">
		<grid:RadDataGrid.Commands>
			<local:CustomCellFlyoutActionCommand />
		</grid:RadDataGrid.Commands>
	</grid:RadDataGrid>
</Grid>
