why do u throw exceptions if properties not found.
espacialy on usercontrols... datacontext null -> property not found -> exception ?
it sucks especially with #22. if i want to make my datacontext changeable :/
BuildingWrapperControl e_26 = new BuildingWrapperControl();
-> e_20.Children.Add(e_26); -> throwing exception !?!??!
common it dont has even a chance to get a datacontext?!
