            foreach (TableCell cell in e.Row.Cells)
            {
                cell.Text = String.Format("{0}","aa");
                if (idx % 2 == 0)
                {
                    cell.BackColor =System.Drawing.Color.Red;
                }
                else
                {
                    cell.BackColor = System.Drawing.Color.Blue;
                    cell.ForeColor = System.Drawing.Color.White;
