注解

SideBarButtonClick单击边栏区域上的按钮时,将引发 该事件。

注意

SideBarButtonClick如果 Button 属性设置为 Move 的控件CommandName位于 该对象的控件的边栏列表SideBarTemplate之外DataList,则事件不会引发事件。

引发事件时,将通过委托调用事件处理程序。 有关详细信息,请参阅 处理和引发事件

OnSideBarButtonClick 方法还允许派生类对事件进行处理而不必附加委托。 这是在派生类中处理事件的首选技术。

继承者说明

在派生类中重写 OnSideBarButtonClick(WizardNavigationEventArgs) 方法时,请务必调用 OnSideBarButtonClick(WizardNavigationEventArgs) 基类的 方法,以便注册的委托接收事件。
