母版中使用UpdateProgress控件遇到的奇怪问题？！
我在母版中使用UpdateProgress控件，控件的内容都不见显示，页面代码：
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:ScriptManager id="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel id="UpdatePanel1" runat="server">
<contenttemplate>
<asp:Label id="Label1" runat="server" Text="Label" __designer:wfdid="w21"></asp:Label>
</contenttemplate>
</asp:UpdatePanel>
<asp:Button ID="btn_1" runat="server" OnClick="Button1_Click" Text="Button" />
<asp:UpdateProgress id="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1">
<progresstemplate>
<IMG src="js/progressbar_long_green.gif" />
</progresstemplate>
</asp:UpdateProgress>
</asp:Content>
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
System.Threading.Thread.Sleep(3000);
Label1.Text = "fsadgklasdjglkjasdglj";
}
}
但是如果不用母版，UpdateProgress里面的内容是可以显示出来的，这是什么问题呢？

你的问题可能是在内容页缺少
<%@ Register Assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
