Parameters

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnDragOver 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.

Notes to Inheritors

When overriding OnDragOver(DragEventArgs) in a derived class, be sure to call the base class's OnDragOver(DragEventArgs) method so that registered delegates receive the event.
