GridView绑定空表提示

当查询结果为空时，不弹出提示，而是直接绑定空表，空表下第一列是说明，代码：

 //如果没有查询到结果，则绑定一个空表，并给出提示
            if (ds.Tables[0].Rows.Count == 0)
            {
                //先给空表添加一新行
                ds.Tables[0].Rows.Add(ds.Tables[0].NewRow());
                //给gridview绑定空表
                this.GV_MCText.DataSource = ds;
                this.GV_MCText.DataBind();
                //获取表行的列数
                int CellCount = this.GV_MCText.Rows[0].Cells.Count;
                //清除一下第一行所有列
                this.GV_MCText.Rows[0].Cells.Clear();
                //在第一行添加一个新列
                this.GV_MCText.Rows[0].Cells.Add(new TableCell());
                //该列覆盖全行
                this.GV_MCText.Rows[0].Cells[0].ColumnSpan = CellCount;
                //最后显示提示字符
                this.GV_MCText.Rows[0].Cells[0].Text = "没有数据";
            }

扩展一下，可以写成类文件，供所有模块调用

 #region 用户查询条件绑定GridView
        public static void BindSearchReturn(GridView gv, string itcode,int search)
        {
            string MySql = "select SaveSearch,Names,CreateDate from GTN_SaveSearch where itcode= '" + itcode + "' and State='0' and SearchType="+search;
            DataTable dt = LenovoFrame.Library.Data.Search.UserPersonSearch.BindSearchParam(MySql);
            if (dt.Rows.Count == 0)
            {
                dt.Rows.Add(dt.NewRow());
                gv.DataSource = dt;
                gv.DataBind();
                int CellCount = gv.Rows[0].Cells.Count;
                gv.Rows[0].Cells.Clear();
                gv.Rows[0].Cells.Add(new TableCell());
                gv.Rows[0].Cells[0].ColumnSpan = CellCount;
                gv.Rows[0].Cells[0].Text = "No Records Found";
               
            }
            else
            {
                gv.DataSource = dt;
                gv.DataBind();
            }
           
        }
