Business Validation Logic Code Smell

Question

Consider the following code:

partial class OurBusinessObject {
    partial void OnOurPropertyChanged() {
        if(ValidateOurProperty(this.OurProperty) ==          


        

Answer 1

It's hard to say without knowing the context or business rules. Generally speaking though, you should just validate at time of input, and maybe once more before persistence, but the way you're doing it won't really allow you to validate since you're not allowing a property to contain an invalid value.
