Is there any way to ignore some properties (on a POCO) when validating a form in ASP.NET MVC3?

Question

i\'ve got a sign up wizard for new user registration. When I try to goto the 2nd page, I get validation errors because my User object hasn\'t been fully populated,

I was just messing with validation forms and ModelState and found out a very easy solution to your problem without writing any new method, overrides etc.

ModelState.Where(m => m.Key == "Avatar").FirstOrDefault().Value.Errors.Clear();
// At  this point ModeState will have an error for that Key,
// by applying Clear it remove the error so modelstate becomes valid again

if (!ModelState.IsValid) {
    return View("User", model);
} else {     
    try  {
        // do something
    } catch {
        TempData["errorMessage"] = "something went wrong";
    }
}
