Question

My model is like this

public class MyModel
{
   string ID {get;set;}
   string Title {get;set;}
   MyOtherModel Meta {get;set;}
}

How to define custom model binder for type (MyOtherModel) so when default binder binds MyModel it calls custom model binder for ‘Meta’ property.
I registered it in App start like:

 ModelBinders.Binders[typeof(MyOtherModel)] = new MyCustomBinder();

but this doesn’t work. Any idea or any good article with more infor regarding to model binders?

There is an article about collections that touches a bit the complex type mapping stuff:

Collections and a bit about complex types

In the other hand this article could give you some useful tips:

I suggest you as a workaround to use a model binder for MyModel class, it’s not a perfect solution but you can refactor it easily once you discover a better solution. : )
