I followed the techique ASP.NET MVC 2: Model Validation from Scott Gu. (http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx).

However I am building a localised web site. How can I localized the error string?

I tried the following by replacing the following:

[RegularExpression(@"\d{4}",ErrorMessage="Must be a 4 digit year")] public Nullable YearOfWork { get; set; }

With the following: [RegularExpression(@"\d{4}",ErrorMessage=Resources.SharedStrings.search_error1)] public Nullable YearOfWork { get; set; }

but I get a complilation error: An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type

Please help!
