Can I use MVC validation attributes within a custom model binder?

Question

I have lots of MVC validation attributes on my model. Everything works great when the defaultModelBinder binds my model on submit. But, I need to create a custom modelbinder. I'd like to continue using my validation attributes. Can I? If so, how?

Answer 1

I'm not sure whether this is possible or not, but one thing I can say is that if it is possible then the extension points for default model binder don't make it very discoverable. I spent several hours one day trying to get this to work to no avail.

In lieu of getting this to work, you can use the Controller's TryValidateModel() methods.
