Namespace: DevExpress.Xpf.Scheduling

Assembly: DevExpress.Xpf.Scheduling.v21.2.dll


public TimeSpan AppointmentSearchInterval { get; set; }

Property Value

Type Description

A TimeSpan value, specifying the search range.


If the current view enables using the navigation buttons (the SchedulerViewBase.NavigationButtonsVisibility is set to NavigationButtonVisibility.Auto or NavigationButtonVisibility.Always), the search for the nearest appointment may create the following problem. 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 the recurrence end date, the search operation results in an endless loop, which hangs the application.

Specify the AppointmentSearchInterval property or use the SchedulerControl.LimitInterval property to solve this problem.

The default value for the AppointmentSearchInterval property is 730 days (2 years). Therefore, by default, appointments older than 2 years won’t be recognized by Navigation Buttons.
