Remarks

The MembershipProvider property identifies the membership provider used to verify user information entered in the PasswordRecovery control.

Membership providers are defined in the Web.config file in the <membership> section.

Setting the MembershipProvider property will change the provider used. If you do not set the MembershipProvider property, it will always return Empty.

This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and ASP.NET Themes and Skins.
