TUniComboBox in Runtime problem

[Francisco Neto]

TUniComboBox created at runtime does not correctly capture the ItemIndex property, only the value initially defined.

Exemple:

var Combo := TUniComboBox.Create(Form);

with Combo do
begin
  Name := 'CtPageSize_Combo';
  Style := csDropDownList;
  OnChange := OnPageSizeChange;

  BeginUpdate();
  Clear();
  Items.Add('5');
  Items.Add('10');
  Items.Add('25');
  Items.Add('50');
  Items.Add('75');
  Items.Add('100');
  EndUpdate();
  ItemIndex := 2;
end;

procedure OnPageSizeChange(Sender: TObject);
begin
  var ComboBox := (Sender as TUniComboBox);

  // Error, returns '25' value
  var Value := StrToInt(ComboBox.Text);
  
  // Same Error, returns ItemIndex = 2  
  var Value2 := StrToInt(ComboBox.Items[ComboBox.ItemIndex]);
end;

Hello,

ItemIndex is zero-based, so ItemIndex = 2 correctly refers to the 3rd item ('25').

Yes, but he always returns 2.

 

The problem I'm having is that it always returns the same value even when selecting a different one.

Which version of uniGUI are you using? And could you create a simple test case?

I resolved..

The problem occurs when trying to use the component within the grid via the PagingBarAuxControl property; if there is no parent component, it does not update the ItemIndex value.
