Comentários

A MembershipProvider propriedade identifica o provedor de associação usado para verificar as informações do usuário inseridas no PasswordRecovery controle.

Os provedores de associação são definidos no arquivo Web.config na <membership> seção .

Definir a MembershipProvider propriedade alterará o provedor usado. Se você não definir a MembershipProvider propriedade, ela sempre retornará Empty.

Essa propriedade não pode ser definida por temas ou temas de folha de estilos. Para obter mais informações, consulte ThemeableAttribute e ASP.NET Temas e Peles.
