The DragEnter event is designed to handle the dragging process. This event fires when the mouse pointer enters the control's client area provided that dragging is being performed. This event is likely to be used if dropping can be performed anywhere within the control (and may be prohibited depending upon the dragged data). The allowed drop effect must be set using the event parameter's Effect property. If dropping is allowed in particular areas within the control, handle the DragOver event.
