Custom Required attribute - property required depending of parent model value

Question

I have a model ProductModel which has: * bool IsNew property * ProductDetailsModel Details property

public class ProductModel
{
    public bool IsNew { get; set; }
    public ProductDetails Details { get; set; }
}

public class ProductDetails
{
    public string Code { get; set; }
    public string Type { get; set; }
    public string Description { get; set; }
    public int Number { get; set; }
}

ProductDetails has some other properties eg. Code, Type, Description, Number

I would like to make Description and Number property of ProductDetailsModel required only if IsNew of ProductModel is set to true.

How to do it?

BTW I have more properties of custom types within ProductModel and I can't move their properties into single ProductModel.

This is more 'business logic' rather than something that should be done inside a model. — Jamie Rees, Jul 14 '15 at 15:32

I found the answer here ASP.NET MVC Conditional validation

It seems the easiest way to do it to implement validation in the Product model.
