    How to validate using RegularExpressionValidator

    Hi everyone,

    I'm using ASP.NET and i designed a page which contains many text boxes. I've used RegularExpressionValidator for validation.

    Now i want to validate a text box which should accept alphabets (a-z and A-Z), comma(,), dot(.), open bracket((), close bracket()), blank space and hypen(-) in any order.
    eg. SD.RE - (ad.sd., sd.we.,)

    To accept all these characters, how to write a expression.


    Can anyone help me.

    -haifriends.

    Thank you.

    This accepts only 3 characters, but i need expression that accepts more than 3 characters. Characters should not accept numbers(0-9), special characters such as #, @, $, %, !.....
    Should accept alphabets, space, hypen(-), dot(.), comma(,), open bracket and close bracket.

    Can anyone help me.

    I'm not sure if it works but try this simple regular expression: [A-Za-z,.()- ]*

    why dont you go to the Regex Library Website. theres literally thousands of Regex expressions catalogued and there is a regex tester, its certinally more helpful than posting messages to an unrelated forum trying to get your answers.
