Property Value
true if the current create-user, change-password, or reset-password action will be canceled; otherwise, false. The default is false.The Cancel property is used to cancel the current CreateUser, ChangePassword, or ResetPassword action. You can cancel the current action by setting the Cancel property to true during the ValidatingPassword event.
If you cancel the current action by setting the Cancel property to true, you can set the FailureInformation property to an exception that describes the reason for the password-validation failure. The calling method will throw the exception that the FailureInformation property is set to. If the FailureInformation property is a null reference (Nothing in Visual Basic), the caller will throw a generic password-validation failure exception.
The following code example shows a ValidatingPassword event that validates the format of the password for the user and cancels the action if the password does not match the required format.
