Question

How can I annotate my model so I can allow only alphabets like A-Z in my text-box?

I know that I can use regex but can anyone show how to do that on text-box property itself using data annotation.

You could annotate your model like this:

[RegularExpression(@"^[a-zA-Z]+$", ErrorMessage = "Use letters only please")]
string TextBoxData {get; set;}

Then in your view you would use the helper

@Html.EditorFor(model => model.TextBoxData)
@Html.ValidationMessageFor(model => model.TextBoxData )
