Occurs before the notification window is shown.

Namespace: DevExpress.ExpressApp.Notifications

Assembly: DevExpress.ExpressApp.Notifications.v22.2.dll


public event EventHandler<NotificationItemsEventArgs> CustomProcessNotifications

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.


Handle the CustomProcessNotifications event to apply custom processing to the notification list received from the Notifications Service. If you do not need to use the default logic in this event, set the Handled property to true and call the NotificationsController.RefreshNotifications method to display the notification list after your custom logic is performed as shown below.

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Notifications;
using DevExpress.Persistent.Base.General;
public class MyController : WindowController {
    protected override void OnActivated() {
        controller.CustomProcessNotifications += Controller_CustomProcessNotifications;
    private void Controller_CustomProcessNotifications(object sender, DevExpress.Persistent.Base.General.NotificationItemsEventArgs e) {
        foreach(INotificationItem item in e.NotificationItems) {
        e.Handled = true;
