備註

GiveFeedback事件允許來源修改滑鼠指標外觀,以便將使用者的視覺化回饋提供拖放作業期間的拖曳事件。The GiveFeedback event allows the source of a drag event to modify the appearance of the mouse pointer in order to give the user visual feedback during a drag-and-drop operation. 視覺化回饋強調拖放作業正在處理中。The visual feedback reinforces that a drag-and-drop operation is in process.

本項目中建立的別名DragDrop.GiveFeedback附加事件,此類別,讓GiveFeedback屬於類別的成員清單時UIElement繼承為基底的項目。This event creates an alias for the DragDrop.GiveFeedback attached event for this class so that GiveFeedback is part of the class members list when UIElement is inherited as a base element. 附加至事件處理常式GiveFeedback事件會附加至基礎DragDrop.GiveFeedback附加事件,並接收相同的事件資料執行個體。Event handlers that are attached to the GiveFeedback event are attached to the underlying DragDrop.GiveFeedback attached event and receive the same event data instance.
