更新面板未在协议中刷新

我用的是阿贾克斯女士的手风琴控制。它正常工作,但我似乎无法让它与更新面板一起工作。我的布局如下:

    <div id="accordion">
     <div><a href="#">Header1</a></div>

        <div class="acc_content">  
    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional"  >

    <ContentTemplate>
    <asp:button id="btnToggle" runat="server" text="toggle"/>

  //my repeater contents go here. The buttons within the repeater cause a postback, but changes cannot be seen unless the page is manually refreshed (since the updatepanel doesn't refresh)
    </ContentTemplate>

    <Triggers>
    <asp:AsyncPostBackTrigger ControlID="btnToggle" EventName="click" />
    <asp:AsyncPostBackTrigger ControlID="btnAdd" EventName="click" /> //this button is outside the updatepanel


    </ContentTemplate>
    </Triggers>
    </asp:UpdatePanel>
    </div>

    <div><a href="#">Header 2 </a></div>
      <div class="acc_content">  
          Content of the second pane
          </div>



    </div>

当我单击按钮时会发生回发,但更新面板从不刷新或更新。我试图添加 UpdatePanel1.Update() 在代码后面为每个回发事件,但没有运气。有什么关于为什么会这样的想法吗?

谢谢
