再次请教AutoCompleteExtender控件的问题：Microsoft JScript 运行时错误: 'Sys' 未定义

Question

我使用微软的AutoCompleteExtender控件，运行时报错：Microsoft JScript 运行时错误: 'Sys' 未定义。我找过网上各种修改web.config的解决办法照着做，都仍然失败，请各位专家提点，谢谢。
1） 报错信息：
Microsoft JScript 运行时错误: 'Sys' 未定义2） 出错地方：脚本波浪线处
//<![CDATA[
Sys.WebForms.PageRequestManager._initialize('TopBar1$ScriptManager1', document.getElementById('aspnetForm'));
~~~~~~~~~~~~~
Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [], 200);
//]]>
3） 我按照网上提示修改的web.config： 特别是按照提示增加了：<add assembly="System.Web.Extensions, Version=1.0.61025.0,Culture=neutral, PublicKeyToken=31bf3856ad364e35"/><!--Add by TTT-->
<add assembly="System.Web.Extensions.Design, Version=1.0.61025.0,Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<system.webServer>整节
<httpHandlers>整节另外，在用户控件中我还依照网友建议把<asp:ScriptManager ID="ScriptManager1" runat="server" AsyncPostBackTimeout="200"> </asp:ScriptManager>放在紧接form的后面。4） 用户控件的代码<form action="/Doings.Web/search.aspx" method="get" runat="server"><asp:ScriptManager ID="ScriptManager1" runat="server" AsyncPostBackTimeout="200"> </asp:ScriptManager>
      <div class="main-search">
        <label><!--<input onclick="this.value == '搜索 ddd' ? this.value = '' : true" size="18" value="搜索 ddd" id="key2" autocomplete="off" onkeyup="beKeyUp();" runat="server"/>-->
        <asp:TextBox onclick="this.value == '搜索 ddd' ? this.value = '' : true" size="18" value="搜索 ddd" id="key" autocomplete="off"  runat="server"/></label>
         
           <ajaxToolkit:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" 
            ServiceMethod="GetCompleteList" 
            ServicePath="../WebService/AutoCompleteSuggestDoings.asmx" 
            Enabled="true" 
            MinimumPrefixLength="2" 
            CompletionSetCount="10"
            TargetControlID="key">
          </ajaxToolkit:AutoCompleteExtender>
      </div>

Answer 3

看看这个系列，写的还不错：
http://www.cnblogs.com/leoo2sk/archive/2008/07/22/1248660.html另外你的问题应该是没有注册脚本吧：<asp:ScriptManager ID="ScriptManager1" runat="server">
  <Scripts>
    <asp:ScriptReference Assembly="Microsoft.Web.Preview" Name="PreviewScript.js" />
  </Scripts>

Answer 4

把ScriptManager 换成为ToolkitScriptManagerAutoCompleteExtender只有ToolkitScriptManager支持
