Hi,

On form1 I have datagridview, in code i add column type DataGridComboboxColumn and next 3 columns with normal text.

Combobox i fill like this:

foreach (DataRow row in ds.Tables["tbluslugi"].Rows)
        {
            nazwa.Items.Add(row["Nazwa"].ToString());
        }

I use event dataGridView1_CurrentCellDirtyStateChanged, after when i choose in combobox some value this event is Launch. But when i want get back value what was chosen, value = false. Value = chosen value when i go to next row and i this case i have to use event CellEndEdit but it`s look bad, when i choose somthing from combobox and nothing happend.

What i want? I want when i choose valuse form combobox (don`t wait to go next row) it`s looking in database this value, get back data and put it in empty cells in this row.

I have another quastion, how to make default item in datagridcombobox ?

I think I understand that you want the values in the text cells to change after a selection is made in the combo box.

If this is the case, use the EditingControlShowing event to setup the combo boxes change event.

Like this

private void dataGridView_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
    if(dataGridView.CurrentCell.ColumnIndex == 1)
    {
        ComboBox cmb = (ComboBox)e.Control;
        cmb.SelectedValueChanged += new EventHandler(cmb_SelectedValueChanged);
    }
}

void cmb_SelectedValueChanged(object sender, EventArgs e)
{
    //Update your 3 text fields here
}

Hope this helps
