Nadya,
The best we can do now is to create your own little builder for your class. Check Ken Levy's and Doug Hennig's websites for info on builder builders.
>When we define a new property for our class in design time is there a way that for this property we can choose from combobox (for example, True, False) like we can choose for default properties?
