Note   You may be able to get away with loading your controls in the Page_Load event handler and maintaining the view state properly. It all depends on whether or not you are setting any properties of the dynamically loaded controls programmatically and, if so, when you're doing it relative to the Controls.Add(dynamicControl) line. A thorough discussion of this is a bit beyond the scope of this article, but the reason it may work is because the Controls property's Add() method recursively loads the parent's view state into its children, even though the load view state stage has passed.

请问上面这段话是什么意思?

你的表单够大呀,这么多数据。

你在Request中的QueryString 和 Form中就可以拿到数据了,无需解析这个东西。

不明白,你是不会语法?再说了,控件状态是控件本身自己维护的。。。
