Event Data

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

Property Description
Cancel Gets or sets whether the event should be canceled. Inherited from CancelRoutedEventArgs.
Handled Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs.
OriginalSource Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs.
RoutedEvent Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs.
Source Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs.
TriggeredReminders Provides access to a collection of reminders which are due.
ViewModel Provides access to the View Model for the invoked window. Inherited from WindowShowingEventArgs<T>.
Window Gets or sets the window to which the event is raised. Inherited from WindowShowingEventArgs<T>.

The event data class exposes the following methods:

Method Description
InvokeEventHandler(Delegate, Object) When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs.
OnSetSource(Object) When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs.


The RemindersWindowShowing event fires after the Reminder Controller adds a reminder which is due, to a SchedulerControl.TriggeredReminders collection and before the default Reminders Window is invoked. You can specify a window for display using the WindowShowingEventArgs<T>.Window property, or not display any window at all by setting the CancelRoutedEventArgs.Cancel property to true.


View Example

private void Scheduler_RemindersWindowShowing(object sender, DevExpress.Xpf.Scheduling.RemindersWindowShowingEventArgs e) {
    if (e.TriggeredReminders.Any(r => r.Appointment.Subject.Contains("test"))) {
        DevExpress.Xpf.Scheduling.Visual.RemindersWindow reminderWindow = new DevExpress.Xpf.Scheduling.Visual.RemindersWindow();
        reminderWindow.DataContext = new DevExpress.Xpf.Scheduling.VisualData.RemindersWindowViewModel(scheduler);
        e.Window = reminderWindow;
