Public Property FetchRange As TimeSpan

Type	Description
TimeSpan

A System.TimeSpan value. The default is 1 month.

Use the FetchRange to lessen the amount of database queries.

FetchAppointments and FetchTimeRegions events load items for the SchedulerControl.VisibleIntervals (the start of its earliest item and the end of its latest item) extended up to the FetchRange.

If the SchedulerControl.VisibleIntervals duration is longer than FetchRange , the FetchRange value is ignored.
