注解

此事件将为此类创建Mouse.PreviewMouseUp附加事件的别名, 因此当继承PreviewMouseUp为基元素时UIElement , 它是类成员列表的一部分。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. 附加到PreviewMouseUp事件的事件处理程序附加到基础Mouse.PreviewMouseUp附加事件, 并接收相同的事件数据实例。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.

事件通常PreviewMouseLeftButtonUp与或PreviewMouseRightButtonUp一起引发, 这对应于按下这两个标准鼠标按钮之一。 PreviewMouseUpThe 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, 但它们是直接路由事件, Mouse.PreviewMouseUp当事件沿事件路由到达此元素时, 将引发相应的按钮特定的事件。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. 请参阅或PreviewMouseLeftButtonUp PreviewMouseRightButtonUp的 "备注"。See Remarks for PreviewMouseLeftButtonUp or PreviewMouseRightButtonUp.
