控件没有放在表格里面

这个问题好办
1.你先用FindControl（）找出page下的DataList控件
DataList dl1 = (DataList)page.*.FindControl("页面上的DataList控件") as DataList;
//*号部分那个单词我忘了怎么写了``你自己.得出来``

2.因为你的另一个DataList是嵌套在你页面上的DataList里面的。所以。。。。。看下面
DataList dl2 = (DataList)dl1.*.FindControl("DataList里嵌套的DataList控件") as DataList
大概就这样，自己去试下，有问题在提出来``
