Event Type



DropCompleted is raised on the drag source element after DragStarting, when the dragged element has been dropped. You can handle this event and take appropriate action based on the DropResult in the event args. For example, if the DropResult is Move, you should delete the original drag source.

DragStarting and DropCompleted are raised only if CanDrag is true.

DropCompleted is a routed event. For more info on the routed event concept, see Events and routed events overview.
