 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            try
            {
                if (e.Row.RowType != DataControlRowType.DataRow) // 非資料行, 離開
                    return;

                //單筆, 取得指定名稱Label物件, 若Text="n/a", 將Text改為空白
                Label lblGvptz_zoom = e.Row.FindControl("lblGvptz_zoom") as Label;
                if (lblGvptz_zoom.Text.Equals("n/a"))
                    lblGvptz_zoom.Text = "";

                //多筆迴圈, 取得Row下所以Cells中的Label物件, 若Text="n/a", 將Text改為空白
                foreach (TableCell cl in e.Row.Cells)
                {
                    foreach (object ctrl in cl.Controls)
                    {
                        if (ctrl is System.Web.UI.WebControls.Label) //判斷ctrl是否為Label物件
                        {
                            Label lblctrl = (Label)ctrl;
                            if (lblctrl.Text.Equals("n/a"))
                                lblctrl.Text = "";
                        }
