TCustomAdapterMultiValueField.DoOnValidateValue Method

Validates values entered by the end-user.

Pascal
procedure DoOnValidateValue(AValue: IActionFieldValue; var AHandled: Boolean); override;
C++
virtual __fastcall DoOnValidateValue(IActionFieldValue AValue, Boolean AHandled);

DoOnValidateValue overrides TAdapterUpdateField's DoOnValidateValue method. If the OnValidateValues event handler is not nil (Delphi) or NULL (C++), it is called it to validate values. If the Required property is true, DoOnValidateValues also validates that 1 of more values have been entered by the end user. An exception will be raised to indicate a validation error.
