Assembly: PresentationCore (in PresentationCore.dll)
Theevent enables the drag source to declare whether the drag-and-drop operation should be canceled.
This event creates an alias for the DragDrop.PreviewQueryContinueDrag 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.PreviewQueryContinueDrag attached event and receive the same event data instance. GTMT
