Comments
The OnDragOver method raises the DragOver event.
Raising an event invokes the event handler through a delegate.
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.
When overriding OnDragOver in a derived class, make sure to call the base class's OnDragOver method so that registered delegates receive the event.
