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. |
Remarks
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.
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;
}
