Reference - Global system events

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

Before
After
Failure

BulkUpdateEventArgs

Properties

• ChangedColumns (IEnumerable<string>)
• TypeInfo (ObjectTypeInfo)
• WhereCondition (IWhereCondition)

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.

Error

Execute

EventArgs

Fires when an error occurs in the application.

SessionStart

Execute

EventArgs

Occurs when an HTTP session starts for a client.

GetVaryByCustomString

Execute

GetVaryByCustomStringEventArgs

Properties

• Result (string)
• Context (HttpContext)
• Custom (string)

Occurs when the application processes variables in custom names of output cache keys.

Prepare

EventArgs

Occurs before the request processing begins.

Begin

Execute

EventArgs

Occurs when the request processing starts.

Authenticate

Execute

EventArgs

Occurs when authenticating requests.

Authorize

Execute

EventArgs

Occurs when authorizing requests. If the application loads the response from the output cache, the life cycle skips to the End event.

PostAuthorize

Execute

EventArgs

Occurs after the request’s user is authorized.

PostResolveRequestCache

Execute

EventArgs

Occurs when ASP.NET bypasses execution of the current handler and allows a caching module to serve the request from the cache. Not used by the Kentico output caching (see the Authorize event).

The system performs URL rewriting during the event. After this event, the application can access the context of the displayed page and current page (page info).

MapRequestHandler

Execute

EventArgs

Occurs when a handler is selected to respond to the request.

PostMapRequestHandler

Execute

EventArgs

Occurs after the application has mapped the request to the appropriate event handler.

AcquireRequestState

Execute

EventArgs

Occurs when acquiring the state (for example session state) that is associated with the current request.

PostAcquireRequestState

Execute

EventArgs

Occurs after the request state (for example session state) that is associated with the current request has been obtained.

End

Execute

EventArgs

Occurs at the end of the request processing.

RunEndRequestTasks

Execute

EventArgs

Allows you to execute background tasks at the end of the 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 cleanup and release any resources used by the request. Running long tasks in this event’s handlers can negatively affect the response time of requests.

UpdateSession

Before
After
Failure

CMSEventArgs

Occurs when an HTTP session is updated.

UpdateSessionData

Execute

CMSEventArgs<SessionInfo>

Properties

• Parameter (SessionInfo)

Occurs when the data of an HTTP session is updated.
