Is there a way to change the TNxComboBoxItem ItemIndex property by code.

I just have try this:
TNxComboBoxItem(myItem).Editor.AsInteger := 1;
myItem.ItemIndex := 1;

but the ComboBox didn't change...

Hi,

you can find a demo here: https://dl.dropbox.c...900180/demo.zip

PROBLEM 1
1. run the demo;
2. click on "insItem1.ItemIndex := 1;" button -> you can see the "insItem1" change item;
3. click on "insItem2.ItemIndex := 1;" button (insItem2 is not visible);
4. click on "insItem2.Visible := True;" button (insItem2 is not visible); -> the item is NOT changed!

PROBLEM 2
1. run the demo;
2. select "Item 1";
3. click on "insItem1.ItemIndex := 1;" button -> the "Item 1" don't change item on ComboBox;

thanks

@array81 in your demo app is a mistake

procedure TForm1.NxButton2Click(Sender: TObject);
begin
insItem1.ItemIndex := 1;
end;
procedure TForm1.NxButton4Click(Sender: TObject);
begin
insItem1.ItemIndex := 1;
end;


I know only a problem when you want change the selected item, then it is not correct displayed,
but here is a workaround....

before you change a property per code

NextInspector1.EndEditing();
NxComboBoxItem1.ItemIndex := 1;

Hi,

Please sorry for delay, again.

Yes, there is a type error in demo. All worked fine.

2) If Item is in edit mode, then you need to act to Editor itself, not to Item.

Best regards
