Please use the following code:
this.radPanel1.PanGesture += radScrollablePanel1_PanGesture;
private void radScrollablePanel1_PanGesture(object sender, PanGestureEventArgs e)
Add several controls in the scrollable panel so the horizontal/vertical scrollbar is shown. If you enable all gestures and try to pan in order to scroll to the added controls, neither the PanGesture event is fired, nor the scrollbar is move.
