gridView 不会了

[手可摘星辰]

查询的时候

 if (e.Row.RowType == DataControlRowType.DataRow)
        {
            GridViewRow gridview = e.Row;
            HtmlAnchor htmla = gridview.Cells[10].FindControl("UpLoad") as HtmlAnchor;
            
            string path = (e.Row.FindControl("Label7") as Label).Text;
            string PayDetailID = hf.Value;
            string year = hfd.Value;
            string parentId = hfdd.Value;
            string paySetId = pay.Value;
           

            string total = string.Empty;
            string sql2 = string.Format(@"SELECT  SUM(SendTotal)as he FROM ProjectPayDetail WHERE dbo.StartsWith(Path,'" + path + "')=1 and ReportID='" + ReportID + "'");
            total = SqlHelper.ExecuteScalar(sql2);

            string sql = string.Format(@"SELECT  SUM(SendTotal)as he FROM ProjectPayDetail WHERE dbo.StartsWith(Path,'" + path + "')=1 AND Path<> '" + path + "' and ReportID='" + ReportID + "'");


            string sql3 = "select SendTotal from ProjectPayDetail where PayDetailID='" + PayDetailID + "'  and ReportID='" + ReportID + "'";
            string total3 = SqlHelper.ExecuteScalar(sql3);
            string total2 = SqlHelper.ExecuteScalar(sql);


            if (parentId == "0")
            {
                htmla.HRef = "FileUpload.aspx?ReportId=" + ReportID + "&PayDetailID=" + PayDetailID + "";
                
                (gridview.Cells[6].FindControl("Label6") as Label).Text = total.ToString();
            }
            else
            {
                htmla.Visible = false;

                if (string.IsNullOrEmpty(total2))
                {
                    (gridview.Cells[6].FindControl("Label6") as Label).Text = total3.ToString();
                }
                else
                {
                    (gridview.Cells[6].FindControl("Label6") as Label).Text = total2.ToString();
                }

            }


        }


    }

但是用自带的编辑的时候就会报错，因为编辑的时候没有Lable怎么判断行的状态呢，或者怎么修改呢

编译，是前台和后台整合，

后台代码的访问是：部分的。

应该不会前台找不到. 标记是不是服务器控件。
