Summary

Validator for custom validation.

run\JvValidators.pas

Pascal

 run\JvValidators.pas

 TJvCustomValidator = class(TJvBaseValidator);

Description

Use a TJvCustomValidator when none of the other validators can perform the validation you need. TJvCustomValidator does not handle validate itself. Instead it delegates the validation to the OnValidate event.
Write an event handler for the OnValidate event that returns whether the validation succeeded or not. You can perform validation without assigning to the ControlToValidate property or to the PropertyToValidate property since this validator doesn't use these properties itself.
