Asp.net mvc2: How to add validation rules - A number field is not required but has range limitation?

Question

This question is pretty thin; if you add more detail, showing perhaps what you have and what is not working, it will be easier to answer. — Dan Davies Brackett

How can a number be optional but still have a restricted range? I'm pretty sure null is not between 1 and 10. — Robert Harvey

Using the Required attribute will not allow 0 whereas a Range attribute from 0 to 255 will. — Marc Tidd

Use the Range Attribute from DataAnnotations.

[Range(0, 255, ErrorMessage="The number must be between 0 and 255.")]
