Answer 2

注意你在前台时加一个属性 <asp:LinkButton ID="linkbutton3" runat="server" CommandArgument ='<%#  DataBinder.Eval(Container.DataItem,"username")%>' CommandName="delete" OnClientClick='return confirm("确认要删除此行信息吗？")'>删除 </asp:LinkButton>再在做删除时取按钮的CommandArgument参数即可

Answer 3

if(e.CommandName=="delete")
{
int iIndex=Convert.ToInt16(e.ComandArgument);
GridViewRow gvr=gridview1.Rows[iIndex];
string username=gvr.Cells[列号].Text;
}
这样也许可以
