The RoleGroup type exposes the following members.

Public methodRoleGroupInitializes a new instance of the RoleGroup class.

Public propertyContentTemplateGets or sets the content template associated with this role group.
Public propertyRolesGets or sets the roles associated with this role group.

Public methodContainsUserIndicates whether the specified user is a member of any of the roles in the role group.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a comma-separated list of the roles associated with this role group. (Overrides Object.ToString.)

You can use the LoginView control to define a set of content templates that contain the content that is displayed to Web site users based on the role assigned by Web site administrators. The RoleGroup class is used by the LoginView control to associate a content template with a set of roles.

To dynamically assign a template to the role group, set the ContentTemplate property to a reference to an object that implements the ITemplate interface.

You must configure role management to use the RoleGroup class. For more information, see Understanding Role Management.

The following code example assigns a custom template to the ContentTemplate property.
