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>
