Namespace: DevExpress.Xpf.Scheduling

Assembly: DevExpress.Xpf.Scheduling.v20.2.dll

NuGet Packages: DevExpress.WindowsDesktop.Wpf.Scheduling, DevExpress.Wpf.Scheduling

Declaration

C#

public DateTime QueryEnd { get; }

VB.NET

Public ReadOnly Property QueryEnd As Date

Property Value

Type	Description
DateTime	A DateTime value that is the end of the appointment.

Remarks

The SchedulerItemBase.QueryStart and QueryEnd properties allow you to calculate the correct interval for use in a SELECT query for SchedulerControl.VisibleIntervalsChanged, DataSource.FetchAppointments, and DataSource.FetchTimeRegions event handlers. The use of the SchedulerItemBase.Start and SchedulerItemBase.End properties is not recommended in this scenario, because their values do not take recurrences into consideration.

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

Appointment Type	QueryEnd Value
AppointmentType.Normal	The SchedulerItemBase.End value.
AppointmentType.Pattern	The End value of the latest Occurrence, ChangedOccurrence or DeletedOccurrence.
AppointmentType.ChangedOccurrence	The QueryEnd value of the pattern.
AppointmentType.DeletedOccurrence	The QueryEnd value of the pattern.
