You are viewing documentation for the legacy WPF Scheduler control. If you’re starting a new project, we strongly recommend that you use a new control declared in the DevExpress.Xpf.Scheduling namespace. If you decide to upgrade an existing project in order to switch to the updated scheduler control, see the Migration Guidelines document.
Handle the RecurrenceFormShowing event to perform any actions before the Appointment Recurrence form is shown. For instance, a custom form can be substituted in place of the standard one (the FormShowingEventArgs.Form property). If you use your own custom Edit Appointment form and it is required to invoke the default Appointment Recurrence dialog from this form, handle the RecurrenceFormShowing event and set the RecurrenceFormEventArgs.Controller property to the appointment editing form’s controller.
The Appointment Recurrence form can be invoked either by an end-user or via the SchedulerControl.ShowRecurrenceForm method.
This example demonstrates how to replace the standard Appointment Recurrence form with a custom one via the SchedulerControl.RecurrenceFormShowing event.
Set the FormShowingEventArgs.Form property to the instance of a class specifying the custom recurrence form with the passed AppointmentFormController controller of the Edit Appointment form (RecurrenceFormEventArgs.ParentForm) from which the Appointment Recurrence form is invoked.
