Occurs when the input system reports an underlying drop event with this element as the drop target.
Assembly: PresentationCore (in PresentationCore.dll)
This event creates an alias for the DragDrop.PreviewDrop attached event for this class, so that is part of the class members list when UIElement3D is inherited as a base element. Event handlers that are attached to the event are attached to the underlying DragDrop.PreviewDrop attached event and receive the same event data instance.
