UIElement.Drop Event


在输入系统报告出现将此元素作为放置目标的基础放置事件时发生。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 


此事件将为此类创建 DragDrop.Drop 附加事件的别名,以便在将 UIElement 作为基元素继承时,UIElement.Drop 是类成员列表的一部分。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. 附加到 Drop 事件的事件处理程序附加到基础 DragDrop.Drop 附加事件,并接收相同的事件数据实例。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.
