NotificationsController.CustomProcessNotifications Event

Occurs before XAF invokes a notification window.

Namespace: DevExpress.ExpressApp.Notifications

Assembly: DevExpress.ExpressApp.Notifications.v24.1.dll

NuGet Package: DevExpress.ExpressApp.Notifications

Declaration

C#

public event EventHandler<NotificationItemsEventArgs> CustomProcessNotifications

VB.NET

Public Event CustomProcessNotifications As EventHandler(Of NotificationItemsEventArgs)

Event Data

The CustomProcessNotifications event's data class is NotificationItemsEventArgs. The following properties provide information specific to this event:

Property	Description
Handled	Gets or sets a value that indicates whether the event handler has completely handled the event or whether the system should continue its own processing. Inherited from HandledEventArgs.
NotificationItems	Gets the list of INotificationItem objects to be processed.

Remarks

Handle the CustomProcessNotifications event to apply custom processing to the notification list received from the Notifications Service. To suppress the default logic, set the Handled property to true and call the NotificationsController.RefreshNotifications method to display the notification list after XAF runs your custom logic.
