ValidateCell Command

Updated on Mar 10, 2026

The ValidateCell command provides an entry point for validating the content of a cell.

Execution Parameter

The execution parameter is of type ValidateCellContext that exposes the following properties:

• CellInfo—Gets the cell information associated with the operation.
• Errors—Gets or sets the errors (if any) that occurred during the validation.

Custom ValidateCell 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 ValidateCell Command

C#

	public class CustomValicateCellCommand : DataGridCommand
	{
	    public CustomValicateCellCommand()
	    {
	        this.Id = CommandId.ValidateCell;
	    }

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

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

			this.Owner.CommandService.ExecuteDefaultCommand(CommandId.ValidateCell, 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:CustomValicateCellCommand/>
			</grid:RadDataGrid.Commands>
		</grid:RadDataGrid>
	</Grid>
