Xceed Input Validator for .NET v.1.0

Features galore. Form-level or control-level validation, Fully customizable and localizable error messages, validate with regular expressions (many included), regular expression tester, wide variety of validation operators and options, and more.
With or without code. Don't like to set properties at design time or use configuration dialogs? Do you want to change validation behavior dynamically at runtime? No problem. It even provides classes designed to be extensible so you can expand its capabilties.
Example. Need to limit a textbox's input to a value between 4 and 42? Select the textbox, and click the 'Configure Validation' verb to set it up. Now, when an invalid value is entered, a warning icon flashes next to the textbox, and hovering the mouse over the icon pops-up an explanation of the problem.
Unique capabilities. How about restricting the values entered in a combo box to a set of predefined values? Or comparing the value contained in one input component with another. Just as easy!
