LMD 2007 - Validator Controls

The LMD Validator framework introduces a set of components which allow implementation of professional-level client-side validation in an elegant and simple way without writing much code (often without any code at all).
The two main tasks of client-side validation are:
- to check for validity a value entered by a user into some input control;
- to provide feedback about validation results (e.g. to indicate an error) in some way.
Consequently, there are three types of components involved into the most typical validation setup :
- input control being validated;
- validator component which encapsulates some validation logic;
- error provider component which implements some way of error indication.
Check LMD Validator Tutorial for an introduction into this interesting technique.
