UIElement.PreviewMouseUp 事件


滑鼠指標在此元素上方且放開任何滑鼠按鈕時發生。Occurs when any mouse button is released while the mouse pointer is over this element.

 event System::Windows::Input::MouseButtonEventHandler ^ PreviewMouseUp;
public event System.Windows.Input.MouseButtonEventHandler PreviewMouseUp;
member this.PreviewMouseUp : System.Windows.Input.MouseButtonEventHandler 
Public Custom Event PreviewMouseUp As MouseButtonEventHandler 


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

PreviewMouseUp 事件通常會連同 PreviewMouseLeftButtonUpPreviewMouseRightButtonUp引發,這會對應至兩個標準滑鼠按鍵的其中一個。The PreviewMouseUp event is often raised together with either PreviewMouseLeftButtonUp or PreviewMouseRightButtonUp, which correspond to a press of one of the two standard mouse buttons. PreviewMouseLeftButtonUpPreviewMouseRightButtonUp 也是路由事件,但它們是直接路由事件,當 Mouse.PreviewMouseUp 事件沿著事件路由到達此元素時,就會引發適當的按鈕特定事件。PreviewMouseLeftButtonUp and PreviewMouseRightButtonUp are also routed events, but they are direct routed events, and the appropriate button-specific event is raised when the Mouse.PreviewMouseUp event reaches this element along the event route. 請參閱 PreviewMouseLeftButtonUpPreviewMouseRightButtonUp的備註。See Remarks for PreviewMouseLeftButtonUp or PreviewMouseRightButtonUp.
