嗨专家，
我们在sharepoint 2013中面临与updatepanel相关的问题。我们有一个包含标签和按钮的示例webpart，我们想写一些东西到单击按钮事件中的标签而不刷新整个页面。我们的示例代码如下：

推荐答案
您不需要这样：
<触发器>
< asp：AsyncPostBackTrigger ControlID =" btn"事件名称= QUOT;按一下[ />
$
< /触发器>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btn" EventName="Click" />
</Triggers>
默认情况下，UpdatePanel中的所有子控件都充当触发器，因此您不需要此部件和它将自动完成工作。
all child controls in UpdatePanel by default act as triggers so you don't need this part and it will automatically do the job.
