Currently, the Diagram control does not register touch event as a click. Therefore, selecting and dragging nodes in the diagram does not work. It only pans the entire view. These show up as Pan events only and no other events seem to fire.
Hello,
The diagram does respond to gestures, select, drag, zoom now. you can test it here on a mobile device or any of the demos:
