Occurs when the input system reports an underlying drag event with this element as the drag target.
Assembly: PresentationCore (in PresentationCore.dll)
This event creates an alias for the DragDrop.DragEnter attached event for this class, so that is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the event are attached to the underlying DragDrop.DragEnter attached event and receive the same event data instance.
