Get the underlying combo of a datagridviewcomboboxcolumn

[baranils]

Hello I'm trying to acceed the combobox property of a datagridview combobox column I can do it using the EditingControlShowing event

// \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*
private void DgvKeys\_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
  if (noEvent)
  {
    return;
  }

  ComboBox combo = e.Control as ComboBox;
}

But I need to acceed directly any combo in some column without having to waint an event on it ! To set the combo selected intex for example I was trying this but it does not work !

    DataGridViewComboBoxColumn cby;
    cby = (DataGridViewComboBoxColumn)DgvKeys.Columns\["Region"\];
    cby.SelectedIndex = cby.FindStringExact(combo.Text);

Any idea ?

Can you describe in more detail the circumstances when you would want to do this?

Thank you Henry "Can you describe in more detail the circumstances when you would want to do this?" Good question ! I have three combobox column on single row (one and only one) Those three combo are binded to three different tables There is a logical relation berween those tables If the user select a value in the third combo I want to show the related value in the first and second cell So I'm trying to force the values of two cell but it doesn't work I'm trying this If I change the appellation Column Pays must shows "France" And Region must Show "Bordeaux" But Pays remain empty !! I thought it was because I also have to change the selected item of the combo ??

  ComboBox combo = (ComboBox)sender;

  if (combo.SelectedItem == null)
  {
    return;
  }

  DataRowView cRowV = (DataRowView)combo.SelectedItem;
  DataRow cRow = cRowV.Row;


  if (combo.DisplayMember == "Appellation")
  {
    DgvKeys.Rows\[0\].Cells\["Pays"\].Value = "France"; // = GetPaysName(cRow\["PaysID"\]);
    DgvKeys.Rows\[0\].Cells\["Region"\].Value = "Bordeaux"; // GetRegionName(cRow\["RegionID"\]);
    curApel = cRow\["Appellation"\].ToString();
    curApelID = Tools.GetInt(cRow\["ApelID"\]);
    noEvent = false;
    return;
  }

Hello ! I've just finded out that a part of the problem seems to come because I've defined a Value Member to my ComboboxColumn If I remove the assignation of the valuemember I can force the value of the cell without problem ???
