Adding multiple Prefixes to DefaultModelBinder MVC2

Question

I've looked at most of the ModelBinding examples but can't seem to glean what I'm looking for.

I'd like:

<%= Html.TextBox("User.FirstName") %>
<%= Html.TextBox("User.LastName") %>

to bind to this method on post

public ActionResult Index(UserInputModel input) {}

where UserInputModel is

public class UserInputModel {
    public string FirstName {get; set;}
    public string LastName {get; set;}
}

The convention is to use the class name sans "InputModel", but I'd like to not have to specify this each time with the BindAttribute, ie:

public ActionResult Index([Bind(Prefix="User")]UserInputModel input) {}

I've tried overriding the DefaultModelBinder but can't seem to find the proper place to inject this tiny bit of functionality.

Answer 1

The BindAttribute can be used at the class level to avoid duplicating it for each instance of the UserInputModel parameter.

======EDIT======

Just dropping the prefix from your form or using the BindAttribute on the view model would be the easiest option, but an alternative would be to register a custom model binder for the UserInputModel type and explicitly looking for the prefix you want.
