How to gain control over model binding?

Question

I started using MVC recently and I\'m getting little disappointed. Instead of helping me, the framework is getting in my way.

I\'m trying to write a controller actio

You can leverage IModelBinder interface and write a complete custom model binder. Here it is explained well. Essentially, this interface exposes a method "BindModel", where you can control model binding behavior along with validation.

However, this might complicate the matter and you might get in spaghetti code. I would suggest a simple "Action per model", if it suites you. So you can write something like this :

ActionResult SaveA(long id, AViewModel)
{
      //.... Action to be conducted in case it is form A.
}
ActionResult SaveB(...., BViewModel)
{
       //... Action to be conducted in case it is form B.
}


// Your view models can be structured for code reuse as well.
class AViewModel {  ...  }
class BViewModel : AViewModel {  ...  }
