UIElement.Drop 事件


輸入系統報告其下以這個項目作為置放目標的置放事件時發生。Occurs when the input system reports an underlying drop event with this element as the drop target.

 event System::Windows::DragEventHandler ^ Drop;
public event System.Windows.DragEventHandler Drop;
member this.Drop : System.Windows.DragEventHandler 
Public Custom Event Drop As DragEventHandler 


這個事件會為這個類別建立 DragDrop.Drop 附加事件的別名,因此當 UIElement 繼承為基底專案時,UIElement.Drop 就會是類別成員清單的一部分。This event creates an alias for the DragDrop.Drop attached event for this class so that UIElement.Drop is part of the class members list when UIElement is inherited as a base element. 附加至 Drop 事件的事件處理常式會附加至基礎 DragDrop.Drop 附加事件,並接收相同的事件資料實例。Event handlers that are attached to the Drop event are attached to the underlying DragDrop.Drop attached event and receive the same event data instance.
