加载aspx页，这是包括在MasterPage的ListView，它包含的UpdatePanel_未分类的问答_编程通用

其实我使用ASP.NET和C＃开发一个模板。
我的模板包括3个部分，我想有局部的清爽，这就是为什么我使用UpdatePanel。
此模板中，一旦用户点击顶部菜单将刷新侧边菜单，然后当用户侧菜单上，单击它会刷新中间的内容页。
在这种情况下我使用的masterpage，因为我要在中间的内容页的aspx页面加载。根据我的代码正常的页面轻松地装载在这一部分，但是，当我想这是包括ListView的加载页面:


    <%@ Page Title="" Language="C#" MasterPageFile=" /MainMasterPage.master" AutoEventWireup="true" CodeFile="ContentPage1.aspx.cs" Inherits="ContentPage1" %>

    <asp:Content ID="Content3" ContentPlaceHolderID="ContentPlaceHolder3" Runat="Server" Visible="true">

    <asp:Panel ID="ContentPanel" runat="server" Visible="true">

        <fieldset style=" height:350px;">

            <legend>Details</legend>

            <asp:Label ID="TestLable" runat="server" Text="This is a test"></asp:Label>

它无法显示页面。我背后的这个ListView的页面代码如下:

{C}
和我的母版加载页面的代码是如下:


<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">

        

 

    </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>

因为我想在第一部分清爽，我设置的ContentPlaceHolder3可见虚假，一旦用户点击相关链接，我只是通过代码设置它作为真正的落后。
你能认罪指导我如何在母版加载这个aspx页面的国王。
感谢你的体贴。
