注解

通过使用设计UpdatePanelTrigger器中的UpdatePanelTrigger 集合编辑器或以声明方式将其添加<Triggers> UpdatePanel为控件内的元素来指定集合中的触发器。Triggers in the UpdatePanelTrigger collection are specified by using the UpdatePanelTrigger Collection Editor in the designer or by adding them declaratively as <Triggers> elements inside the UpdatePanel control. 可以添加两种类型的触发器:You can add two types of triggers:

  • 一个AsyncPostBackTrigger对象, 该对象可用于指定控件可能导致异步回发并刷新更新面板的内容。An AsyncPostBackTrigger object that can be used to specify that a control can cause an asynchronous postback and refresh the update panel's contents. 对象用于更新面板以外的控件或不是UpdatePanel控件的直接子控件的控件。 AsyncPostBackTriggerThe AsyncPostBackTrigger object is used for controls outside an update panel or controls that are not immediate child controls of an UpdatePanel control.

  • 一个PostBackTrigger对象, 该对象可用于指定UpdatePanel控件内的回发控件可能导致同步回发和整页刷新。A PostBackTrigger object that can be used to specify that a postback control inside an UpdatePanel control can cause a synchronous postback and a full-page refresh.
