    Angry regular expression validator

    I have a small problem. I have a form called customer master. I have a textbox control which is supposed to accept the phone number. The phone number can accept hyphen , but not at the beginning. It can begin with + at the beginning. Other than these two it should accept only numbers. I want to know how to validate this at run time not at design time.

    can anyone help me with this.

    Thanking you,

    Sai abhiram Bandhakavi.

    Use this as the ValidationExpression property:
    (\+\d{3}-\d{3}-\d{4}|\d{3}-\d{3}-\d{4})

    Don't forget to set your ControlToValidate property

    This tool might help you out in future - it allows you to test your regular expressions quickly. Also there is a search facility for existing regular expressions.
