ContentType attribute

This topic describes the ContentType attribute, used in Optimizely to define a set of properties needed when creating content types such as pages and blocks.

Configurable properties

The ContentType attribute is required for all content types, is located in the EPiServer.DataAnnotations namespace and has the following configurable properties.

PropertyDescriptionDefault value
AvailableInEditModeDefines whether you can create content of this type in edit view.true
DescriptionText that describes the function of the ContentType.NULL
DisplayNameThe name shown in edit view for this ContentType.NULL
OrderThe sort order used to determine the ContentType’s position in listings.100
GUIDIdentifier for the ContentType. You can match the code definition to an existing definition in the database.Guid.Empty
GroupNameName for grouping ContentTypes when you display them for selection in edit view.NULL

Access

The optional Access attribute defines which users, roles, and visitor groups have access rights to create content of a specific type in the user interface. Filtering based on this attribute is applied after ordinary access rights on content.

📘

Note

If the Access attribute is not present, any user (who has edit access) can create content of the specific type.

PropertyDescriptionBehavior if not specified
Users, Roles, VisitorGroupsDefines which users, roles, and visitor groups have access rights.No user has access to ContentType.

AvailableContentTypesAttribute

Use AvailableContentTypesAttributes to set which content types are available under a content instance; it has the following configurable properties.

PropertyDescriptionDefault value
AvailabilityDefines whether all or no content types are available. If you set none, other settings on the attribute is ignored.Availability.All
IncludeA type array of typed content to specify which content types are available under a content instance of the type with the attribute.Type[0]
ExcludeA type array of typed content to specify which content types are not available under a content instance of the type with the attribute.Type[0]
IncludeOnStates that the content with this attribute is available under the typed content in the type array.Type[0]
ExcludeOnStates that the content with this attribute is not available under any of the typed content in the type array.Type[0]

The types given on Include, Exclude, IncludeOn and ExcludeOn can be either a typed content directly or it can be the type of an interface or a base class. At registration, registered types that can be assigned to the specified type are included. For example, if an interface is specified in an Include list, then typed pages that implement the interface are included.

The following image shows how Include differs from IncludeOn and how they are mapped in admin view. 

  • Include excludes typed content except that which is specified.
  • IncludeOn does not exclude any content type for types that have all content types available.
