RadGridView DESELECT a Row

[Devid]

After I open my application and select a Row in RadGridView, I would like on Esc button click to deselect that row, is that possible ? If yes how ?
Thanks

Hello Devid,

The desired behavior can be achieved by creating a custom KeyboardCommandProvider and overriding it's ProvideCommandsForKey like so:

public override IEnumerable<ICommand> ProvideCommandsForKey(Key key)
{
    List<ICommand> commandsToExecute = base.ProvideCommandsForKey(key).ToList();

    if (key == Key.Escape)
    {
        commandsToExecute.Clear();
        parentGrid.SelectedItems.Clear();
    }

    return commandsToExecute;
}

Please let me know if this works for you.

Thank you. I added a event KeyDown  to my RadGridView and implemented it like this and it works:

 

private void GlobalUiRadGridView_OnKeyDown(object sender, KeyEventArgs e)
        {
            if (Keyboard.IsKeyDown(Key.Escape))
            {
                this.MyRadGridView.KeyboardCommandProvider = new                                     EscapeCustomKeyboardCommandProvider(this.MyRadGridView);
            }
        }

Hello Devid,

Rather than set RadGridView's KeyboardCommandProvider each time the Escape key is pressed, I would suggest you set that only once in the window's constructor as suggested in the article I referenced. You may also do that in RadGridView's Loaded event.

public MainWindow()
{
    InitializeComponent();
    this.MyRadGridView.KeyboardCommandProvider = new EscapeCustomKeyboardCommandProvider(this.MyRadGridView);
}

public class EscapeCustomKeyboardCommandProvider : DefaultKeyboardCommandProvider
{
    private GridViewDataControl parentGrid;

    public EscapeCustomKeyboardCommandProvider(GridViewDataControl grid)
     : base(grid)
    {
        this.parentGrid = grid;
    }

    public override IEnumerable<ICommand> ProvideCommandsForKey(Key key)
    {
        List<ICommand> commandsToExecute = base.ProvideCommandsForKey(key).ToList();

        if (key == Key.Escape)
        {
            commandsToExecute.Clear();
            parentGrid.SelectedItems.Clear();
        }

        return commandsToExecute;
    }
}

I hope you find this suggestion helpful.
