A DragEventArgs that provides data for the event.

This method checks any parent control for a drag-and-drop handler that can handle the operation instead. If one exists, this method passes the DragEventArgs to the method and returns. If no parent drag-and-drop handler exists, this method attempts to create a tool if a toolbox item has been dropped on the designer control.
