CellHolding Command

Handles the Hold gesture on a grid cell, that is, the intersection of a data row and a column. The default implementation will attempt execute CellFlyoutAction command for the cell specified. The execution parameter is of type CellHoldingContext which exposes the following properties:

• HoldingState: Gets the HoldingState reported from Holding event.
• CellInfo: Gets the DataGridCellInfo instance this cell is associated with, giving access to its column and data item.

The following example first creates a class that inherits from the DataGridCommand and then adds it to the RadDataGrid.Commands collection.

public class CustomCellHoldingCommand : DataGridCommand
{
    public CustomCellHoldingCommand()
    {
        this.Id = CommandId.CellTap;
    }

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

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

Here is the XAML declaration:

<grid:RadDataGrid>
    <grid:RadDataGrid.Commands>
        <local:CustomCellHoldingCommand/>
    </grid:RadDataGrid.Commands>
</grid:RadDataGrid>
