System.Web.Security Namespace
.NET Framework version 2.0
Provides event data for the ValidatingPassword event of the MembershipProvider class.
The ValidatingPassword event is raised when the CreateUser, ChangePassword, or ResetPassword method of a membership provider is called.
You can handle the ValidatingPassword event to validate password formats and values for membership users.
You can cancel the current CreateUser, ChangePassword, or ResetPassword 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.
