Question

I have a class with a property which has a range attribution on it.

        [Required]
        [Range(5, 9999)]
        public double Price { get; set; }

Which is respected at all times and on any user input.

But on one specific code path, where i am automating some entries, i want to be able to set the Price to 0. So i want to programmatically tell this model class to ignore this requirement.

Is it possible? If so how?

This seems like a duplicate of this question, but maybe I’m not completely understanding your requirements.

For your scenario I might try implementing the IValidatableObject interface so that way you can control the validation logic rather than using a declarative validation pattern.
