How to Prevent the Selection While Pressing Right Click in WPF / UWP TreeGrid?

This example illustrates how to prevent the selection while pressing right click in WPF TreeGrid and UWP TreeGrid (SfTreeGrid).

For WPF:

You can prevent the selection when right-clicking in TreeGrid by customizing the SelectionController and overriding the ProcessPointerPressed.

protected override void ProcessPointerPressed(MouseButtonEventArgs args, RowColumnIndex rowColumnIndex)
{
    if (args.ChangedButton == MouseButton.Right)
    {
        args.Handled = true;
    }
    else
        base.ProcessPointerPressed(args, rowColumnIndex);
}

For UWP:

You can prevent the selection when right-clicking in TreeGrid by customizing the SelectionController and overriding the ProcessPointerPressed.

protected override void ProcessPointerPressed(PointerRoutedEventArgs args, RowColumnIndex rowColumnIndex)
{
    var properties = args.GetCurrentPoint(TreeGrid).Properties;
    if (properties.IsRightButtonPressed)
    {
        args.Handled = true;
    }
    else
        base.ProcessPointerPressed(args, rowColumnIndex);
}
