Drag & Drop
To implement Drag & Drop, you have to: The behaviour of the control that receives a drop is the following:
  1. If you don't implement the Drag event handler, nor the DragMove event handler, then:
    • If the Drop event handler is implemented, then the drop is accepted.
    • Otherwise, it is rejected.
  2. If you implement the Drag event handler, and if the event is stopped, then the drop is rejected and no DragMove event is raised.
  3. If you implement the DragMove event handler, and if the event is stopped, then the drop is rejected.
