如何获取命名空间中的控件id(gridview,label等）

本想偷懒，使用了Article的模版建立.net网站，结构发现了2个头疼的命名空间。在default页面没法调用gridview等控件的id。求高手指点。

gridview1 和 label1 都没法在 default.aspx.cs中自动显示出来。控件实在找不到。求高手指点。 --------------------编程问答-------------------- CodeFile="details.aspx.cs" Inherits="details" 是否正确 --------------------编程问答-------------------- 那个我知道，文件名不重要。
--------------------编程问答-------------------- 通过Content 的ID的FindControl去找 --------------------编程问答--------------------

引用 3 楼的回复:

通过Content 的ID的FindControl去找

高手，代码咋弄啊，asp.net不太熟。命名空间弄得乱。请赐教啊。 --------------------编程问答-------------------- 还有，只能找到<artisteer:Block id="HighlightsBlock2" Caption="" runat="server" >
的id，但是findcontrol不到label --------------------编程问答-------------------- 求高手啊
--------------------编程问答-------------------- 你可以采用递归找到任何控件。

没有你的全部代码，没法给写成具体的代码的。
自己要学会调试。
你可以启用Trace功能，查看控件树

补充：.NET技术 ,  ASP.NET
