  • The corresponding bubbling event is DragOver.

  • Override OnPreviewDragOver to implement class handling for this event in derived classes.

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