Solution 1

pls try this

C#

foreach (GridViewRow row in gvClassRooms.Rows)
            {
                if (!string.IsNullOrEmpty(row.Cells[1].Text))
                {
                     Sql = "insert into TB_Room_Allocation_SMS (RoomNo,Minor_Code) " +
                    "values( '" + row.Cells[0].Text + "','" + row.Cells[1].Text + "')";
                    scon.ExecSql(Sql);
                }

                if (!string.IsNullOrEmpty(row.Cells[3].Text))
                {
                    Sql = "insert into TB_Room_Allocation_SMS (RoomNo,Minor_Code) " +
                   "values( '" + row.Cells[2].Text + "','" + row.Cells[3].Text + "')";
                    scon.ExecSql(Sql);
                }

                Label4.Text = "Records Inserted Successfully";
                scon.Con.Close();
