其实我正在开发一个模板使用ASP.net和C＃。
正如你可以看到下面的图片，我的模板包括3部分，我想部分刷新，这就是为什么我使用updatepanel。
在这个模板中，一旦用户点击顶部菜单，它将刷新侧面菜单，然后当用户点击侧面菜单时，它将刷新中间内容页面。 我在这种情况下使用母版页，因为我打算在中间内容页面加载aspx页面。根据我的代码正常的页面很容易在这部分加载，但是当我要加载它的页面包括列表视图：加载aspx页面，其中包含listview包含更新面板主页页面

它没有显示的页面。我的这个列表视图页面背后的代码如下：

，我的母版的代码加载这个页面如下：
<asp:UpdatePanel ID="UpdatePanel3" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<!-- Initial the Page which is going to show the details of the sub-menu -->
<asp:ContentPlaceHolder id="ContentPlaceHolder3" runat="server" Visible="false">
</asp:ContentPlaceHolder>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="Button2" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="Button3" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="Button4" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="LinkButton1" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="LinkButton2" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="LinkButton3" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="LinkButton4" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="LinkButton5" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="LinkButton6" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="LinkButton7" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="LinkButton8" EventName="Click" />
<asp:AsyncPostBackTrigger ControlID="LinkButton9" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
，因为我想起初我将可见有部分令人耳目一新将ContentPlaceHolder3的值设为false，并且一旦用户点击相关链接，我只是通过代码将其设置为true。 
你可以请求指导我如何在masterpage上加载这种aspx页面。 感谢您的考虑。
