datalist中嵌套 GridView1如何触发更新事件

这里GridView1_RowUpdating没有执行..........郁闷中 --------------------编程问答-------------------- 自己先顶下 --------------------编程问答-------------------- 很好，很强大 --------------------编程问答-------------------- 用addhandler方式添加 --------------------编程问答-------------------- 顶下先再看 --------------------编程问答-------------------- 按照常规的做法应该就可以了 --------------------编程问答-------------------- --------------------编程问答-------------------- --------------------编程问答-------------------- <asp:CommandField ShowDeleteButton="True" />
修改下这个就行了
<asp:CommandField ShowDeleteButton="True"  CausesValidation="false" />

补充：.NET技术 ,  C#
