asp.net ajax UpdatePanel控件使用

请问一下 我要现有web项目中使用Updatepanel 会提示有错误:Sys未定义  难道用这个控件还要新建一个asp.net AJAX-Enabled Web Site 才行吗?

    =======这样最好,因为WEBCONFIG里会帮你配好的

    ajax该配得都要配好，该装的都要装好才能跑起来。

    正好遇到过这个问题，在webconfig中加入:
    <httpHandlers>
             <remove verb="*" path="*.asmx"/>
             <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
             <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
             <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
    </httpHandlers>
    <compilation debug="true">
     <assemblies>
             <add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
    </assemblies>
    </compilation>注意不要把compilation节重复了。
