Oh... So in that case I can't do what I want. Except if I create a Form with a PropertyGrid control inside, which will popup in Design Time, when user click on specific Property on Properties Window? Is than an option? Can I do something like that?

I agree!!! CustomBackColor and CustomFont was fake property names, just for example!!!
