the answer :D

private const UInt32 WM_KEYDOWN = 0x0100;

    public bool PreFilterMessage(ref Message m)
    {
        if (this.ActiveControl is DataGridViewTextBoxEditingControl)
        {
            if (m.Msg == WM\_KEYDOWN)
            {
                Keys keyCode = (Keys)(int)m.WParam & Keys.KeyCode;

                if (keyCode == Keys.Enter)
                {

                    if (this.dgvReadInsert.CurrentCell.ColumnIndex == 4 || this.dgvReadInsert.CurrentCell.ColumnIndex == 10 || this.dgvReadInsert.CurrentCell.ColumnIndex == 6 || this.dgvReadInsert.CurrentCell.ColumnIndex == 12 || this.dgvReadInsert.CurrentCell.ColumnIndex == 13 || this.dgvReadInsert.CurrentCell.ColumnIndex == 14)

                        this.dgvReadInsert.CurrentCell = this.dgvReadInsert\[6, this.dgvReadInsert.CurrentCell.RowIndex + 1\];

                    return true;

                }
            }

            return false;

        }

        return false;

    }

after inherit from class form1 : Form, IMessageFilter
