>Technically, I agree. Practically, I disagree. In most cases, I will store tel, zip fields with formatting because then I can just drop the field on a report, or drag it onto a form and it will display correctly. Otherwise every end use of this field requires formatting. eeuw.
But then why not have a PhoneNoTextBox class and use it wherever you need it? Though, I'd just love it if I could use it on a report as well.
