关于使用Ajax ，toolkit时出现的的错误提示，大家来看看。
昨天装了个AjaxControlToolkit,
今天在aspx中加了个tabpanel1控件，提示说：呈现控件时出错—Tabpanel1
然后我运行的时候提示脚本错误：
行：407
字符：13
错误：Sys.InvalidOperationException:owner   must   be   set   before   initialize
代码：0
我在在网上查了，查不到这个错误提示。我在csdn上求救了，希望大家能给我点提示。
这个错误提示要怎么解决啊？
这个tabpanel控件要怎么用啊？




------解决方案--------------------
写的不明不白。应该是有个属性或方法没有初始化。

看看web.config有没有配置好
