The CreateUserWizard.QuestionAndAnswerRequired property returns a value from the membership provider set in the CreateUserWizard.MembershipProvider property specifying whether the user is required to enter a password confirmation question and answer.

If a Membership provider requires a question and answer, the CreateUserWizard.Question and CreateUserWizard.Answer controls are required and the System.Web.UI.WebControls.CreateUserWizard throws an exception if they are not found or of the wrong type. If they are not required by the Membership provider, no exception is thrown if they are not found, and if they are of the wrong type they are ignored.
