Thanks! I just figured this out.

>>Is there way to detect in control's Init method code that control added in run-time? For example:
>>
>> procedure Init
>> lAddedInRuntype = ????
>> if lAddedInRuntype
>> ... special actions
>> endif
>> endproc

>At the end of your base form's Init() set a custom property lInitFinished = .T.
>Default this property to .F.
>In each control's base class (i.e., your base classes) check for form.lInitFinished = .T. - if it is, it was added at run time.
