Is it possible to use ASP.NET MVC 2's DataAnnotations to only allow characters (no number), or even provide a whitelist of allowed strings? Example?
Use the RegularExpressionAttribute.
would match a-z upper and lower case and spaces.
A white list would look something like
which should only allow "white" and "list"
\D represents non numeric characters so the above should allow a string with anything but 0-9.
Regular expressions are tricky but there are some helpful testing tools online like: http://gskinner.com/RegExr/
