From TCheckListBox to TcxCheckListBox with an exception? - delphi

Question

I use this code with TCheckListbox (lbServices) and it works fine. But with TcxCheckListBox from Devexpress it raise exception.
procedure TMaintenanceForm.AfterConstruction;
var
i: Integer;
ActionObj: TAction;
begin
inherited;
for i := 0 to ServiceActionList.ActionCount-1 do
begin
ActionObj := ServiceActionList.Actions[i] as TAction;
lbServices.Items.AddObject(ActionObj.Caption, ActionObj);
end;
end;
procedure TMaintenanceForm.btnStopClick(Sender: TObject);
begin
fContinue := False;
end;
procedure TMaintenanceForm.cmdExecuteSelectedClick(Sender: TObject);
var
i: Integer;
begin
Screen.Cursor := crHourGlass;
try
for i := 0 to lbServices.Count -1 do
if lbServices.Selected[i] then
(lbServices.Items.Objects[i] as TAction).Execute; // Exception here!!!!
finally
Screen.Cursor := crDefault;
end;
end;
If I debug the code lbServices.Count = 12.
lbServices.Items.Objects[i] is nil for all items in the list. What is wrong here ?

Answer 1

Use the following code instead:
var
AItem: TcxCheckListBoxItem;
begin
AItem := cxCheckListBox1.Items.Add;
AItem.ItemObject := Action1;
AItem.Text := Action1.Caption;
end;
...
var
I: Integer;
begin
for I := 0 to cxCheckListBox1.Items.Count - 1 do
if cxCheckListBox1.Items[I].Checked then
(cxCheckListBox1.Items[I].ItemObject as TACtion).Execute;
end;

There is no Objects property of TcxCheckListBox.Items
