Remarks
Important
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.
When a Navigation Button determines its state and visibility, it searches for appointments beyond the visible interval. If the calculation algorithm encounters recurring appointments in the filtered appointment subset, it searches for the end of the recurrence chain. If the appointment does not specify a recurrence end date, the search operation results in an endless loop, which hangs the application.
To prevent this undesired behavior, use the NavigationButtonAppointmentSearchInterval property to specify a reasonable search interval.
