c# - XAML designer intellisense-like structured suggestion -

with given class (containing hundreds of constants)

public class objects {     public class cars     {         public class opel         {             public const string corsa = "some parameters";             ...         }         public class ford { ... }         ...     } } 

it easy find needed constant in code behind (talking intellisense suggestions):

var parameter = objects.cars.opel.corsa; 

when typing objects. prompted cars, after typing objects.cars. there suggestion opel, ford, etc. , after object.cars.opel there suggestion corsa (among others).

my question approach should use provide same kind of suggestion in xaml designer?

to example, if have markup extension , i'd assist programmer in choosing proper value out of list, make enum, set property of type , rest happens auto-magically:

however, when dealing hundreds of constants i'd prefer have kind of structured selection, similar described earlier intellisense support nested classes suggestion.

and struggling find nice way of how organize that. ideas?
