   前台的模板列中通过红色字体 将当前行号绑定给  CommandArgument

 
 <asp:TemplateField HeaderText="操作"ItemStyle-HorizontalAlign="Left" ItemStyle-VerticalAlign="Middle">
<ItemTemplate>
 <asp:Button ID="btnRejCorp"Text="驳回" runat="server"CommandName="CorpDateReject" CommandArgument='<%#Container.DataItemIndex %>'/>
 </ItemTemplate>
 </asp:TemplateField>

 

后台

 protected voidgridCorpReport_RowCommand(object sender, GridViewCommandEventArgse)
       {
           if (e.CommandName == "CorpDateReject")
           {

                             int LB = Int32.Parse(e.CommandArgument.ToString());

                              varlbl =(HyperLink)gridCorpReport.Rows[LB].FindControl("lblcorptip");
               string corpid = gridCorpReport.Rows[LB].Cells[0].Text;

           }
