SchedulerNavigationButtonOptions.AppointmentSearchInterval Property

Specifies the time span used by Navigation Buttons to search for the nearest appointments (in days), so it is limited to a reasonable range.

Namespace: DevExpress.XtraScheduler

Assembly: DevExpress.XtraScheduler.v19.2.Core.dll


public TimeSpan AppointmentSearchInterval { get; set; }
Public Property AppointmentSearchInterval As TimeSpan

Property Value

Type Description

A System.TimeSpan value, specifying the search range.


When Navigation Buttons search for the nearest appointment, the following problem may arise. If the calculation algorithm encounters recurring appointments in the filtered appointment subset, it searches for the end of the recurrence chain. If the appointment doesn't specify the recurrence end date, the search operation results in an endless loop, which hangs the application.

To solve the problem, you may use the SchedulerControl.LimitInterval property or specify the AppointmentSearchInterval.

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