Use Regular Expressions to validate such specific input validation needs. Use this tool to test your RegExs: RegEx Validator.

Simple regex ^.*(?=.{8,})(?=.*\d)(?=.*[a-zA-Z]).*$ in custom validator

Hi,
Use the following Regular Expression to validate your TextBox.

C#

^(?=.{8,})(?=.*[a-z])(?=.*[@#$%^&+=]).*$
