How to add ASCII char to regex validation annotation?

Question

I want to validate textbox is it only text. But I need some special chars for Eastern Europe such as

č,ć,š,đ,Č,Ć,Š,Đ,ž,Ž (ASCII is for e.g: & #269;)

I have this validation which is just fine but it not supports my special chars:

 [RegularExpression(@"^[a-zA-Z]+$", ErrorMessage = "Use letters only please")]

I've tried to add like this but I failed:

 [RegularExpression(@"^[a-zA-Z]+$&#269", ErrorMessage = "Use letters only please")]

If you know way around I would appreciate it.

Why put them outside the character class? Use [RegularExpression(@"^[a-zA-Z\u010D]+$", ErrorMessage = "Use letters only please")] or use literals: [RegularExpression(@"^[a-zA-ZčćšđČĆŠĐžŽ]+$", ErrorMessage = "Use letters only please")] — Wiktor Stribiżew

You should put them inside the character class.

Use something like (and add hex values with \u notation):

[RegularExpression(@"^[a-zA-Z\u010D]+$", ErrorMessage = "Use letters only please")]

or use literals (easier and more maintainable):

[RegularExpression(@"^[a-zA-ZčćšđČĆŠĐžŽ]+$", ErrorMessage = "Use letters only please")]
