Catch the right click of the mouse and highlight only the cell in datagridview

Hi folks,

I have a datagridview with filled cells in it. If I click right a contexrmenu pops up. How can I select the cell and only the cell which must be highlighted when I click the cell and not the entire row. Th ecode I tryed:

            if (e.Button == MouseButtons.Right)
            {
                dgvLoginReaparatie.Rows[e.RowIndex].Selected = true;
            }

All in the MouseDown event.

Thanks

Full of ideas but don´t know how.
