Conditional Model Binding with ASP.net MVC 2

Question

I am using model binding (with a strongly typed partial view) for my validation of a search form.

For a "live" search I require city, date, time and other things, but for a "city" I only require city.

Is there a way to set the required attribute on my model conditionally, based on whether a hidden input "searchtype" is set?

Or is model binding, not going to work in this situation?

Answer 1

Out of the box, there isn't any kind of RequiredIfAttribute, but MVC FoolProof validation has these plus many other useful validation attributes.
