        {
            string type = dttax.Rows[0]["Spare_one"].ToString();
            switch (type)
            {
                case "A1":
                    if (Convert.ToDecimal(dttax.Rows[0]["one"]) > 0)
                        sb.Append("window.open('2A+.aspx?oid=1')");
                    else
                        sb.Append("window.open('2A.aspx?oid=1')");
                    break;
                case "A2":
                    if (Convert.ToDecimal(dttax.Rows[0]["one"]) > 0)
                        sb.Append("window.open('2A+2.aspx?oid=1')");
                    else
                        sb.Append("window.open('2A2.aspx?oid=1')");
                    break;
                case "B1":
                    sb.Append("window.open('B.aspx?oid1')");
                    break;
                case "B2":
                    sb.Append("window.open('B2.aspx?oid=1')");
                    break;
