Topic: Hiding combobox items ?

How can I hide combobox items on a button click?

I have two forms
Form1 with Button1 and Button2
Form 2 has a combobox with Item1, Item2, Item3, Item4. Combobox items (data) added manually in SQLiteStudio.


If Button1 clicked
Show only combobox Item1 and Item 3
If Button2 clicked
Show only combobox Item1, Item 2 and Item4


I couldn't translate the above into MVD script that works?

Hi,
This way keeps the script small but I'm sure there are other approaches.

Hi Derek,


Nice and neat solution... Thank you very much...... Truly appreciated......


Perhaps Dmitry can offer full script version within MVD only, just to have an alternative.

Another way

procedure Form1_Button2_OnClick (Sender: string; var Cancel: boolean);
begin
  form1.combobox1.dbfilter := 'id=1 or id=3';
  form1.combobox1.dbupdate;
end;

procedure Form1_Button1_OnClick (Sender: string; var Cancel: boolean);
begin
  form1.combobox1.dbfilter := 'id=1 or id=2 or id=4';
  form1.combobox1.dbupdate;
end;
