Answer 1

嵌套的GridView-- detailGrid 如何绑定数据（DataSet）detailGrid 的数据，我不想在前台用SqlDataSource来绑定，后台如何实现？
我是在detailGrid_DataSelect这个事件中绑定，但不知道如何实现。

Answer 2

发生GridView绑定时激发时间， 然后在这个事件中获取到DataList或Reapter然后跟其绑定 DataSet就可以了！

Answer 3

发生GridView绑定时激发事件ItemData....忘了

Answer 4

目前只能采用 dataSource做的 ，期待大侠有别的方法...
