Instant validation, no code! Simply drag and drop it onto any Windows Form and it will add validation properties directly to all compatible controls.

For most controls, a warning icon can flash next to them when a validation error occurs. Hover the mouse over the icon for an explanation of the rule.

Form-level or control-level validation, fully customizable and localizable error messages, validation with regular expressions (many included), regular expression tester, wide variety of validation operators and options, and more.
