Delegate

DragEventHandler

  • The corresponding bubbling event is DragEnter.

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

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 ContentElement 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.
