DataGridView Selected Row Move UP and DOWN

Question

How can I allow selected rows in a DataGridView (DGV) to be moved up or down. I have done this before with a ListView. Unfortunetly, for me, replacing the DGV is not an opt

   DataGridViewRow BeginingRow = new DataGridViewRow();
   int BeginingRowIndex ;   
        private void DataGridView1_CellMouseUp(object sender, DataGridViewCellMouseEventArgs e)
    {
        if (e.Button != MouseButtons.Left ||e.RowIndex < 0 ) return;
            if (BeginingRowIndex > e.RowIndex)
            {
                DataGridView1.Rows.Insert(e.RowIndex);
                foreach (DataGridViewCell cellules in BeginingRow.Cells)
                {
                    DataGridView1.Rows[e.RowIndex].Cells[cellules.ColumnIndex].Value = cellules.Value;
                }
                DataGridView1.Rows.RemoveAt(BeginingRowIndex + 1);

            }
            else
            {
                DataGridView1.Rows.Insert(e.RowIndex +1);
                foreach (DataGridViewCell cellules in BeginingRow.Cells)
                {
                    DataGridView1.Rows[e.RowIndex+1].Cells[cellules.ColumnIndex].Value = cellules.Value;
                }
                DataGridView1.Rows.RemoveAt(BeginingRowIndex);
            }

            DataGridView1.RowsDefaultCellStyle.ApplyStyle(BeginingRow.DefaultCellStyle);
            DataGridView1.Rows[e.RowIndex].Selected = true;
    }

    private void DataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
    {
        if (e.Button != MouseButtons.Left ||e.RowIndex < 0 ) return;
                BeginingRowIndex = e.RowIndex;
                BeginingRow = DataGridView1.Rows[BeginingRowIndex];
                BeginingRow.DefaultCellStyle = DataGridView1.Rows[BeginingRowIndex].DefaultCellStyle;
    }
