(1)动态改变GridView 行标题，
RowCreated是每次呈现的时候都要触发。

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.Header)
            {
                string sjzf = db.DLookup("score", "DWPY_Paper", "isuser = '是'");
                string zpzf = db.DLookup("sum(fs)", "DWPY_Question", "paperid in(select id from DWPY_Paper where isuser = '是' ) and type = '自评'");
                TableCellCollection tcHeader = e.Row.Cells;
                tcHeader[3].Wrap = false;
                tcHeader[3].Text = "个人自评分数</br>总分:<span style='color:red'>" + zpzf + "</span>";
                tcHeader[4].Text = "领导评价分数</br>总分:<span style='color:red'>" + (decimal.Parse(sjzf) - decimal.Parse(zpzf)).ToString() + "</span>";
            }
        }

(2)RowDataBound是数据绑定的时候才会触发。

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            DataRowView drv = (DataRowView)e.Row.DataItem;

           if (e.Row.RowType == DataControlRowType.DataRow)
            {
                GridViewRow gvr = e.Row;
                string qid = drv.Row["id"].ToString();

            }

         }
