            if (this.dgFee.RowCount > )
            {
                dgFee.FirstDisplayedScrollingRowIndex = Math.Min(dgYY.FirstDisplayedScrollingRowIndex, this.dgFee.RowCount - );
                dgFee.HorizontalScrollingOffset = dgYY.HorizontalScrollingOffset;
            }
        }

            if (this.dgYY.RowCount > )
            {
