推荐答案

要拨打回发活动，请尝试下面

To call postback event , try below

<Triggers>
 <asp:PostBackTrigger ControlID="Button1"  />
 </Triggers>
 </asp:UpdatePanel>

< postbacktrigger>指定将导致整页更新（整页刷新）的控件和事件。当控件以其他方式触发部分渲染时，此标记可用于强制完全刷新。

<postbacktrigger> Specifies a control and event that will cause a full page update (a full page refresh). This tag can be used to force a full refresh when a control would otherwise trigger partial rendering.
