裸奔3000M,只求一解

不知道用什么实现以上需求，gridview 嵌套，还是。

解决方案 »

  1.   

    给个事例GridView模版列嵌套GirdView显示主从表数据
    当需要在一个列表中显示主从表（例如部门-人员的信息），在asp.net1.1中我们可能会使用DataGrid模版列嵌套DataGrid的方法实现，然而，处理模版列里的DataGrid的翻页、排序、编辑等功能时都比较麻烦。在asp.net2.0中，配合DataSource控件的使用让这个问题变得非常简单！

    我们从来都是 <%foreach%>里面套<%foreach%>  cs文件里面准备好数据实体的List就可以了    reapter都不用  太麻烦  出了问题还不好控制
