Summary

Occurs when the custom validator needs to know if the validation is to succeed or not.

Pascal

 TJvCustomValidateEvent = procedure (Sender: TObject; ValueToValidate: Variant; varValid: Boolean) ofobject;
propertyOnValidate: TJvCustomValidateEvent;

Parameters

Parameters	Description
Valid	Set this parameter to true if the validation was successful, to false otherwise.
ValueToValidate	The value to validate.
Sender	The object that triggered the event.

Description

Write a handler for the OnValidate event to perform the validation. OnValidate is called by the Validate function and the return value from this event is returned by Validate. If you don't assign an event handler, Validate always returns true.
