What is the execution order of drag & drop related dialog control blocks?
The table below shows the order in which the runtime system executes the control blocks related to drag & drop events:
| Context / User action | Control block execution order | 
|---|---|
| The user starts to drag an object from the source dialog. | 
                     
  | 
               
| The mouse cursor enters the drop target dialog. | 
                     
  | 
               
| After entering the target dialog, the mouse cursor moves from row to row, or user chooses to change the drop operation (move or copy). | 
                     
  | 
               
| The user releases the mouse button over the target dialog. |
