<script type="text/javascript">
//<![CDATA[
if (typeof(Sys) === 'undefined') throw new Error('ASP.NET Ajax 客户端框架未能加载。');
//]]>
</script>

处理:

system.web中加

 <globalization requestEncoding="utf-8" responseEncoding="utf-8"/>

错误2:ScriptManager is required ASP.NET AJAX Script Component

解决:用ToolkitScriptManager

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">  
   <cc1:ToolkitScriptManager runat="Server" EnablePartialRendering="true" ID="ScriptManager1" />

        Height="255px" Width="741px" ForeColor="Red" ScrollBars="Auto">
        <cc1:TabPanel ID="jbdj" runat="server" HeaderText="TabPanel1">
            <HeaderTemplate>
                登记<br />
            </HeaderTemplate>
            <ContentTemplate>
                <asp:Label ID="Label1" runat="server" Text="登记" Width="143px"></asp:Label>
            </ContentTemplate>
        </cc1:TabPanel>

</cc1:TabPanel>

错误3:编译器错误信息: CS0433: 类型“System.Web.UI.ScriptManager”同时存在于“c:/WINDOWS/assembly/GAC_MSIL/System.Web.Extensions/1.0.61025.0__31bf3856ad364e35/System.Web.Extensions.dll”和“c:/WINDOWS/assembly/GAC_MSIL/System.Web.Extensions/3.5.0.0__31bf3856ad364e35/System.Web.Extensions.dll”中
