Joe, It's not the only way, but it certainly is the quickest way as without using classes you would have to long hand code each textbox or use copy/paste in the designer once you got one field working. The great thing about using a class is that it is a one step cures all solution with one point for the "bespoke" validation coding i.e in the class itself.
Many people are initially put off by the thoughts f rolling their own classes but once you have done it once you'll appreciate the flexibility of being able to subclass even your bespoke classes to any level if required.

I have never fully understood the process off defining my own classes. I thought in this case I could simply use an existing class but could not figure out how to set the Valid function. Do I understand correctly that the only way to control such functions is to define my own class?
