DataGridViewCom boBoxColumn return wrong index.

[PIERREWHY]

I have a datagridview containing a datagridviewcom bobox.
The combobox has a dataset containing city_name and city_id.
When I select a new city_name in the combobox I would like to return the city_id corresponding to that city_name.

Code:

//City ComboBox
comboboxCity.Da taPropertyName = "city_name" ;
comboboxCity.He aderText = "City";
comboboxCity.Da taSource = city_table;
comboboxCity.Va lueMember = "city_name" ;
comboboxCity.Di splayMember = comboboxCity.Va lueMember;
comboboxCity.Na me = "comboboxCi ty";
dgvVSK.Columns. Insert(20, comboboxCity);

This is the code where I retrieve the selected index after selecting a new city in the combobox.

Code:

private void comboboxControl Showing(object sender, DataGridViewEdi tingControlShow ingEventArgs e)
{
comboBox1 = e.Control as ComboBox;

if (comboBox1 != null)
{
comboBox1.Selec tedIndexChanged += new EventHandler(co mboBox1_Selecte dIndexChanged);

}
}


private void comboBox1_Selec tedIndexChanged (object sender, EventArgs e )
{
if (comboBox1 != null)
{
dgvVSK.Rows[dgvVSK.Selected Rows[0].Index].Cells["city_id"].Value = ((ComboBox)send er).SelectedInd ex.ToString();
}
}

I do return the selectedindex for that combobox. But it does not correspond to the city_id but to the table row index.

Thanks,
Pierre

dgvVSK.Rows[dgvVSK.Selected Rows[0].Index].Cells["city_id"].Value = ((ComboBox)send er).SelectedInd ex.ToString();

Maybe this is the probelm else do,

dgvVSK.Rows[dgvVSK.Selected Rows[0].Index].Cells["city_id"].Value = ((ComboBox)send er).SelectedVal ue.ToString();
