Property Value

Type	Description
DateTime	A DateTime value that is the normalized appointment start time.

Remarks

The QueryStart and QueryEnd properties allow you to specify the correct interval when querying the collection of appointment source objects. The use of the DxSchedulerAppointmentItem.Start and DxSchedulerAppointmentItem.End properties is not recommended because you can miss the appointment pattern and lose appointment exceptions.

The QueryStart property return values are dependent on the appointment type, as shown in the following table:

Appointment Type	QueryStart Value
OneTime	The DxSchedulerAppointmentItem.Start value
Pattern	The Start value of the first appointment in the series.
ChangedOccurrence	The Start value of an original occurrence before modification (as if an occurrence is restored from the exception).
DeletedOccurrence	The Start value of an original occurrence before modification (as if an occurrence is restored from the exception).
