CellTap Command

Handles the Tap gesture over a grid cell, that is, the intersection of a data row and a column. The default implementation will attempt to change the current selection, based on the RadDataGrid.SelectionMode and RadDataGrid.SelectionUnit values. The execution parameter is of type DataGridCellInfo which exposes the following properties:

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

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

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

    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               
    }
}

Here is the XAML declaration:

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