ObjectEvents

Namespace: CMS.DataEngine

Contains events that occur for all types of objects in the system. See also: Handle object events

Important

Use the following classes to access the object events in the API:

ObjectEvents – events triggered for all object types
<name>Info.TYPEINFO.Events – events triggered only for a specific object type, for example: UserInfo.TYPEINFO.Events

Event	Event types	Handler parameters	Description
Insert	Before After Failure	ObjectEventArgs Properties Object (BaseInfo)	Occurs when a new object is created. To reliably handle all possible object creation events, you may also need to assign a matching handler to the BulkInsert event. The system triggers the BulkInsert event instead of Insert in certain cases, particularly for operations that can affect multiple objects.
Update	Before After Failure	ObjectEventArgs Properties Object (BaseInfo)	Occurs when the data of an existing object is updated. To reliably handle all possible object update events, you may also need to assign a matching handler to the BulkUpdate event. The system triggers the BulkUpdate event instead of Update in certain cases, particularly for operations that can affect multiple objects.
Delete	Before After Failure	ObjectEventArgs Properties Object (BaseInfo)	Occurs when an object is deleted. To reliably handle all possible object deletion events, you may also need to assign a matching handler to the BulkDelete event. The system triggers the BulkDelete event instead of Delete in certain cases, particularly for operations that can affect multiple objects.
BulkInsert	Before After Failure	BulkInsertEventArgs Properties InsertedObjects (IEnumerable<IInfo>) TypeInfo (ObjectTypeInfo)	Occurs when the system performs object creation operations that can affect multiple objects. To reliably handle all possible object creation events, assign matching handlers to both the BulkInsert and Insert events.
BulkUpdate	Before After Failure	BulkUpdateEventArgs Properties ChangedColumns (IEnumerable<string>) TypeInfo (ObjectTypeInfo) WhereCondition (IWhereCondition)	Occurs when the system performs object update operations that can affect multiple objects. To reliably handle all possible object update events, assign matching handlers to both the BulkUpdate and Update events.
BulkDelete	Before After Failure	BulkDeleteEventArgs Properties TypeInfo (ObjectTypeInfo) WhereCondition (IWhereCondition)	Occurs when the system performs object deletion operations that can affect multiple objects. To reliably handle all possible object deletion events, assign matching handlers to both the BulkDelete and Delete events.
Sort	Before After Failure	ObjectSortEventArgs Properties Object (BaseInfo) Ascending (bool) OrderColumn (string) NameColumn (string)	Occurs when sorting of objects is requested.
ChangeOrder	Before After Failure	ObjectChangeOrderEventArgs Properties Object (BaseInfo) NewOrder (int) RelativeOrder (int) OrderColumn (string)	Occurs when a change in the order of objects is requested.
GetData	Before After Failure	ObjectDataEventArgs Properties Data (DataSet) Query (IObjectQuery) TotalRecords (int)	Occurs when the system retrieves object data using the ObjectQuery API. The Before event type is suitable, for example, when you want to retrieve data from an external source. Assign the external data into the Data property of the handler’s ObjectDataEventArgs parameter, which is empty by default in the Before event. Use the After event type if you need to edit the data retrieved from Xperience in the Data property. The Total Records property provides a number of total records in case paging is used. Use -1 to use the rows count of the Data property.

ContentItemEvents

Namespace: CMS.ContentEngine

Contains events that occur when changes are made to content items.

Event	Event types	Handler	Handler parameters	Description
Create	Before After Failure	Advanced handler	CreateContentItemEventArgs	Occurs when a new content item (not a language variant) is created.
CreateLanguageVariant	Before After Failure	Advanced handler	CreateContentItemLanguageVariantEventArgs	Occurs when a new language variant of an existing content item is created.
UpdateDraft	Before After Failure	Advanced handler	UpdateContentItemDraftEventArgs	Occurs when a draft is updated.
Publish	Execute	Basic handler	PublishContentItemEventArgs	Occurs when an item is published. Also triggers when the system publishes an item that was scheduled to be published. The scheduling action itself triggers the `UpdateLanguageMetadata` event for the item.
Unpublish	Execute	Basic handler	UnpublishContentItemEventArgs	Occurs when an item is unpublished. Also triggers when the system unpublishes an item that was scheduled to be unpublished. The scheduling action itself triggers the `UpdateLanguageMetadata` event for the item.
Delete	Execute	Basic handler	DeleteContentItemEventArgs	Occurs when an item is deleted.
UpdateMetadata	Before After Failure	Advanced handler	UpdateContentItemMetadataEventArgs	Occurs when an item’s metadata is updated (e.g., security settings).
UpdateLanguageMetadata	Before After Failure	Advanced handler	UpdateContentItemLanguageMetadataEventArgs	Occurs when an item’s language variant-specific metadata is updated (e.g., administration display name). This metadata includes the time when an item is scheduled to be published or unpublished. As a result, scheduling an item to be published or unpublished (or canceling a scheduled publish action) triggers the `UpdateLanguageMetadata` event, not `Publish` or `Unpublish`. These events are triggered when the system actually publishes or unpublishes the item.

General information

Events are not cancelable. If you try to cancel an event, an exception is thrown instead. You can also throw exceptions to stop the corresponding operation. For example, an exception thrown from an event while creating an object will roll back the transaction.

Event handlers

Advanced handler

Events handled by advanced handlers expose property setters in their event args that can be used to further modify the item before it is stored in the database. Content type-specific data can be updated via the ContentItemData property, if present.

Basic handler

Events handled by basic handlers are only used for notification.

UpdateLanguageMetadata	Before After Failure	Advanced handler	UpdateWebPageLanguageMetadataEventArgs	Occurs when a page’s language variant-specific metadata is updated (e.g., administration display name). This metadata includes the time when a page is scheduled to be published pr unpublished. As a result, scheduling a page to be published or unpublished (or canceling the scheduled publish action) triggers the `UpdateLanguageMetadata` event, not `Publish` or `Unpublish`. These events are triggered when the system actually publishes or unpublishes the page.

Event types

Handler parameters

Description

MoveToStep

Execute

WebPageWorkflowMoveToStepArguments ContentItemWorkflowMoveToStepArguments HeadlessItemWorkflowMoveToStepArguments

Occurs when a page/content item/headless item is moved from one workflow step to another.

The event arguments allow you to access the name of the current and original workflow step, the user who changed the step, and also properties of the given page, content item or headless item (ID, name, content type, language, etc.).

The event is not triggered when an item is published or scheduled to be published. For publish transitions, you need to handle the Publish or UpdateLanguageMetadata event of WebPageEvents, ContentItemEvents or HeadlessItemEvents.

Example: Set up custom workflow notifications

Application events

Xperience provides a set of events that you can use to customize the global behavior of the application.

ApplicationEvents

Namespace: CMS.Base

Contains events related to the application life cycle.

The following table lists the events that occur once in the application’s life cycle, in order of execution:

Event	Event types	Handler parameters	Description
PreInitialized	Execute	EventArgs	Occurs when the application finishes pre-initialization (preparation of things unrelated to the database). Handlers need to be assigned in the PreInit method of custom modules.
Initialized	Execute	EventArgs	Occurs when the application finishes initialization and starts (including all modules and the database connection). Handle this event to perform standard application start events.
PostStart	Execute	EventArgs	Occurs at the end of the first application request. Allows you to perform asynchronous tasks needed for application startup. Running long operations within this event’s handlers can negatively affect the response time of the first request when starting the application.
End	Execute	EventArgs	Occurs when the application ends.

The following events occur as needed during the application life cycle:

Event	Event types	Handler parameters	Description
Error	Execute	EventArgs	Fires when an error occurs in the application.

RequestEvents

Namespace: CMS.Base

Contains events related to the handling of requests.

The following table lists available events in the order they are invoked by the application:

Event	Event type	Handler parameters	Description
Prepare	Execute	EventArgs	Occurs before request processing begins.
Begin	Execute	EventArgs	Occurs when request processing starts.
PreSendRequestHeaders	Execute	EventArgs	Occurs just before ASP.NET sends HTTP headers to the client. Note: Added delegates are invoked during HttpResponse.OnStarting.
End	Execute	EventArgs	Occurs at the end of request processing.
RunEndRequestTasks	Execute	EventArgs	Allows you to execute background tasks at the end of request processing. Running long tasks in this event’s handlers can negatively affect the response time of requests.
Finalize	Execute	EventArgs	Occurs when the request is finalized. Use to clean up and release any resources used by the request. Running long tasks in this event’s handlers can negatively affect the response time of requests.
