<!-- 需要动态更新的部份放到updatepanle里面(更新不刷新) -->
<atlas:UpdatePanel ID="p1" runat ="server" >
<!-- 更新部分内容 -->
<ContentTemplate >
<asp:Label ID="Label1" runat="server"></asp:Label>
</ContentTemplate>
<!-- 更新条件 -->
<Triggers>
<!-- 控件的某个值改变 -->
<atlas:ControlValueTrigger ControlID ="DropDownList1" PropertyName ="SelectedValue" />
<!-- 控件的某个事件激发 -->
<atlas:ControlEventTrigger ControlID ="Button1" EventName ="Click" />

此代码实现的效果：改变DropDownList1选项或单击Button1后页面(这里仅是Label1显示的内容)更新但是不刷新！
