单击Gridview中LinkButton,获取当前行索引及某单元格值

    1、在Gridview中添加模板列，在其中加入Linkbuttion,增加CommandName属性(设置命令名)，并赋值

       <asp:TemplateField HeaderText="记录编号">
          <ItemTemplate>
             <asp:LinkButton ID="lbtnRecordid" CommandName="lbtn" runat="server" ForeColor="Blue" Text='<%# DataBinder.Eval(Container.DataItem,"recordid") %>'></asp:LinkButton>
         </ItemTemplate>
      </asp:TemplateField>

    2、在Gridview的RowCommand事件中加入代码,例如：

      protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
     {
        if (e.CommandName == "lbtn")
        {
            GridViewRow gvrow = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer); //获取被点击的linkButton所在的GridViewRow
            int index = gvrow.RowIndex; //获取到行索引 RowIndex
            
            //获取当前行的某列值
            string userid=GridView1.Rows[index].Cells[列索引].Text.Trim();

            ......

        }     
       }
