1、无数据依然显示表头

    // 参数：所要绑定的GridView      所要绑定的数据集  
    public void BindNoRecords(GridView gridView, DataSet ds)
    {
        if(ds.Tables[0].Rows.Count == 0)
        {
            ds.Tables[0].Rows.Add(ds.Tables[0].NewRow());
            gridView.DataSource = ds;
            gridView.DataBind();
            int columnCount = gridView.Rows[0].Cells.Count;
            gridView.Rows[0].Cells.Clear();
            gridView.Rows[0].Cells.Add(new TableCell());
            gridView.Rows[0].Cells[0].ColumnSpan = columnCount;
            gridView.Rows[0].Cells[0].Text = "没有任何记录！";
            gridView.RowStyle.HorizontalAlign = System.Web.UI.WebControls.HorizontalAlign.Center;
        }
    }

2、BoundField的格式化字符串

     DataFormatString="{0:F}" 还要加上HtmlEncode="false"才会生效。
     至于{0:F}格式请参照 String.Format格式说明
