如何在后台(.cs文件中)动态添加Ajax中的AutoCompleteExtender(自动完成)控件？
如题：
我在页面中放置了两个TextBox文本框，TextBox1采取直接添加AutoCompaleteExtender的方法，TextBox2则采取在后台动态添加的方法，调试运行时，第一个一切正常，第二个没有反应。不知道是什么原因，代码如下：
Default2.aspx文件：
<%@ Page Language= "C# " AutoEventWireup= "true " CodeFile= "Default2.aspx.cs " Inherits= "Default2 " %>
<%@ Register Assembly= "AjaxControlToolkit " Namespace= "AjaxControlToolkit " TagPrefix= "cc1 " %>

<head runat= "server ">
<title> 无标题页 </title>

<body>
<form id= "form1 " runat= "server ">
<div>
<asp:ScriptManager ID= "ScriptManager1 " runat= "server ">
</asp:ScriptManager>
<asp:UpdatePanel ID= "UpdatePanel1 " runat= "server ">
<ContentTemplate>
<asp:TextBox ID= "TextBox1 " runat= "server "> </asp:TextBox>
<cc1:AutoCompleteExtender ID= "AutoCompleteExtender1 " runat= "server " TargetControlID= "TextBox1 "
ServicePath= "~/Journey_Manage/AutoCompleteWebService.asmx "
ServiceMethod= "GetJourneyCity "
MinimumPrefixLength= "2 "
CompletionInterval= "100 "
EnableCaching= "true "
CompletionSetCount= "10 ">
</cc1:AutoCompleteExtender>
<asp:TextBox ID= "TextBox2 " runat= "server "> </asp:TextBox>
</Conten
