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,

Answer 1

I had a reference entity that wasn't supposed to be validated.

Removed it from validation at the beginning of the action:

[HttpPost]
public async Task Post([FromBody] Contact contact)
{
  var skipped = ModelState.Keys.Where(key => key.StartsWith(nameof(Contact.Portfolios)));
  foreach (var key in skipped)
    ModelState.Remove(key);
    //ModelState doesn't include anything about Portfolios which we're not concerned with

  if (!ModelState.IsValid)
    return BadRequest(ModelState);

  //Rest of action
}
