    Hi, 

    I think I have found a problem with the drag and drop behavior.

    I have implemented the drag and drop as explained in the documentation, but when I test with a touch screen, it doesn't work.

    I think it's because only OnMouseDownLeft(MouseEventArgs e) function is overrided in RowSelectionGridBehavior class, but can't find a way to handle that.

    Hello, Florian,

    Thank you for writing.  

    RadGridView's drag and drop functionality should be handled differently when using gestures. You can override the RadGridView.OnPanGesture method and start the service when it is necessary. The following forum thread is quite useful on this topic: https://www.telerik.com/forums/touch-drag-and-drop-between-two-grid-views

    I hope this information helps. Should you have further questions I would be glad to help. 
     
     Regards,
    Dess
