My class diagram:

BaseContentClass

• Page inherits BaseContentClass
• Tab inherits BaseContentClass
• ...

If I do this

ModelBinders.Binders.Add(typeof(BaseContentObject), new BaseContentObjectCommonPropertiesBinder());

then when in controller action parameter of type Tab appears, custom model binder is not fired.

It gets fired if I do this:

ModelBinders.Binders.Add(typeof(Tab), new BaseContentObjectCommonPropertiesBinder());

But I don't want to go writing "n" number of Add statements in my global.asax.cs to associate all the derived classes with my custom model binder, do I? I don't know if I have any other option.
