Hi,

How to select a item by code ?

With fgComboBox.ItemIndex the item is selected but y can not modify the selection with the finger.

Hello,

What do you mean "y can not modify the selection with the finger"?

Do you mean TComboEdit functionality?

Thank you,
Yaroslav

Hello Yaroslav,

In this form, i fill the combox "cbbSerie" with a query from a database. When i close the form i save the modification to database and no problem at this point.

When a reopen the form (for modification for example), i want to select the datas form the database with this code :

procedure TFormTempsSaisie.fgFormShow(Sender: TObject);
var
  vlRQ: TUniQuery;
begin
  ListerSerie;
  ListerPoste;
  if vfAM = 'A' then
  begin
    nvbMain.Subtitle := 'Nouvelle saisie';
  end
  else
  begin
    nvbMain.Subtitle := 'Modification saisie n° ' + IntToStr(vfIDTemps);
    vlRQ := TUniQuery.Create(nil);
    with vlRQ do
    begin
      Connection := dmdDatas.conBase;
      SQL.Add('Select TE_SERIE, TE_DEBUT, TE_FIN, PO_NOM');
      SQL.Add('From Temps');
      SQL.Add('Join Poste On Poste.PO_COMPTEUR = Temps.TE_POSTE');
      SQL.Add('Where TE_COMPTEUR = :TE_COMPTEUR');
      ParamByName('TE_COMPTEUR').AsInteger := vfIDTemps;
      Open;
      if not Eof Then
      begin
        cbbSerie.ItemIndex := vfListeSerie.IndexOf(FieldByName('TE_SERIE').AsString);
      end;
      Close;
    end;
    FreeAndNil(vlRQ);
  end;
end;

The Combobox Item is correctly selected from the database, but the combox is "like" readonly, i can not select another item.

I suppose the problem is the "ItemIndex" property ?

I have join the complete code of the project.

Thanks for your help.

Hello,

Unfortunately I don't have UniDAC. Do you have demo sample without it?

Thank you

Update: I wrote my demo sample with filling items  and selecting ItemIndex after it in OnShow event. And it works fine. So please, provide another sample without UniDAC.

Hello,

I wrote a simple demo with my problem and some screenshot in the Pdf.

Thank you.
