这个验证有点难~GridView（自动生成的）更新时验证。。。
一下是 GridView和数据源的全部代码。。帮忙看看怎么加验证啊。。。比如要某个字段只能是int。。。。每个字段都不为空什么的。。。怎么加验证？找了半天资料也没找到。。都是用的模板列做的。。。。要不就是手动写的跟新代码。。。。。。还有就是怎么在这个情况下加一个删除提示。。。。要是自己手动写的话。。我知道怎么写但是现在想知道在自动生成的这个情况下怎么写。。。。自动生成要别自己手动写要快很多啊。。。。高手帮看看啊<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateColumns="False"
