最新添加的记录标识

利用sql 表中的标识字段作为键码，该值总是递增的。

在GRIDVIEW的ROWDATABOUND事件中获取改标识字段的值，可以得到最新添加的记录标识

  protected void gvsbls_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        string str1;

        int tmpflag = 0;

        if (e.Row.RowType == DataControlRowType.DataRow)
        {//空记录时不能设置
            Button btnHiddenPostButton2 = e.Row.FindControl("btn2") as Button;
            if (btnHiddenPostButton2 != null)
            {
                str1 = btnHiddenPostButton2.ClientID;
                e.Row.Attributes[" = String.Format("javascript:document.getElementById('{0}').click()", btnHiddenPostButton2.ClientID);
                // 额外样式定义
                e.Row.Attributes[" = "javascript:this.style.background='yellow'";
                e.Row.Attributes[" = "javascript:this.style.background=''";
                e.Row.Attributes["style"] = "cursor:pointer";
                e.Row.Attributes["title"] = "单击当前记录可查看批复结果";

                tmpflag = Convert.ToInt16(e.Row.Cells[11].Text);

                if (tmpflag > maxflag) maxflag = tmpflag;

            }
            // 若希望将隐藏按钮单独放于一列，则设置此列隐藏，占位符 <cellIndex> 表示此列索引

        }
