Question

I have coded a model binder to return a simple model. I want to bind this model to every controllers without change any controller action parameters. Is there anyway to do it?

Thanks!

Answer 1

A model binder is usually associated to a given type. So in your Application_Start:

ModelBinders.Binders.Add(typeof(SomeViewModel), new SomeModelBinder());

This will register the SomeModelBinder model binder to all controller actions which take a SomeViewModel as parameter. For example:

public ActionResult Foo(SomeViewModel model)
{
    ...
}
