Occurs when the input system reports an underlying drag event with this element as the potential drop target.
Assembly: PresentationCore (in PresentationCore.dll)
This event occurs even if the drag originates in the element bounds. If the drag starts outside the bounds and then moves inside, this event is also raised, as well as DragEnter and related preview events.
This event creates an alias for the DragDrop.DragOver attached event for this class so that is part of the class members list when ContentElement is inherited as a base element. Event handlers that are attached to the event are attached to the underlying DragDrop.DragOver attached event and receive the same event data instance.
