一个错误，比较怪异，求救

这个错误在调试过程中没有任何提示的，一直到PageLoad的最后一句都没有错误。

一如既往，没人回答，不过我自己貌似找到原因了，这个跟后台没关系，而跟手风琴选项卡有关系，手风琴选项卡好像只能作为ext:region的子控件布局。

不过这问下其他问题。比如
CheckBoxList list in this.form1.Controls
这一句就出现无法转化的的错误，因为两个control类型不同，如果
CheckBoxList list in this.SimpleForm1.Controls
这样写的话，虽然后面的类型还是webcontrol，但是由于后面的结果集是零，就不在检测类型匹配不匹配。请问如何解决这一问题。或者有什么变通的方法。
