ScriptManager控件问题
我在添加scriptmanager控件的时候，为什么在HTML代码上不添加了一行代码：<%@ Register Assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"Namespace="System.Web.UI" TagPrefix="asp" %>；
这行代码删掉以后，会报未知的控件scriptmanager,有人遇到过这个问题没，调用的时候还会报"Sys"未定义的错误。是不是我的VS的版本的问题,哪个大侠指导一下！！！ --------------------编程问答-------------------- 用来引用ScriptManager所在的Assembly的指令，不能删除。 --------------------编程问答-------------------- asp.net ajax需要引用dll,而且需要web.config进行一下配置的.不然就会报Sys未定义.你如果不想每个页面都加那个,直接加web.config里面

--------------------编程问答-------------------- up.你把那段代码删除了，当然会出错了。 --------------------编程问答-------------------- <%@ Register Assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Namespace="System.Web.UI" TagPrefix="asp" %>；
这行代码在页面上注册了System.Web.Extensions程序集，其中包含了scriptmanager，sys等，所以删除这行，就会报错。
推荐用2楼的方式，在web.config中注册这个程序集。
如果是新建网站，在向导中选择ASP.NET AJAX-enabled Web site 或 ASP.NET Futures AJAX Web site，VS会自动配置好web.config。 --------------------编程问答-------------------- scriptmanager控件不在asp.net自己的程序集里，而是在外部System.Web.Extensions.dll
就像你要使用其他第三方的控件一样，需要引用进来先
补充：.NET技术 , C#
