Define the owner to whom the events of a drag & drop process are sent.
The owner is the object to whom the events of an active drag & drop process are sent. The value of the access is defined in the method bDragDropClient:Init().
If the drag & drop process is managed by an object of the class bDragDropManager, then the events of the drag & drop process are sent to the method CellDragDrop(). The method must be defined in the CommandOwner otherwise a run-time error occurs.
