Using of datagridviewcomboboxcolumn c#

Question

Hello good afternoon.

I have a problem with a DataGridViewComboBoxColumn that I have added to my datagriview, it already has data that I bring from the database.

When I select an item and when passing to the next cell, the value that it had, for example, I select Sales instead of leaving Sales in the cell, it changes to its ID. This happens when I move to the next cell.

Please what should I change or what would be my mistake.

please help me solve my problem thank you very much.

 

this is the code with which I load the data

private void CargarGrupo()
        {

            GrupoId.DataSource = tblGrupoComprasGasto.ListaGrupoComprasEgresos();
            GrupoId.ValueMember = "Id";
            GrupoId.DisplayMember = "NombreGrupo";

        }

 Thank you very much for your collaboration
