Event Type


This event creates an alias for the DragDrop.PreviewDragEnter attached event for this class, so that PreviewDragEnter is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the PreviewDragEnter event are attached to the underlying DragDrop.PreviewDragEnter attached event and receive the same event data instance.
