Raises the Control.DragEnter event.
- A System.Windows.Forms.DragEventArgs that contains the event data.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The IDropTarget.OnDragEnter(DragEventArgs) method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
