Reminder.DstBehavior Property

Sets the reminder behavior if it falls on the Daylight Saving Time shift. Use the SchedulerStorageBase.ReminderDstBehaviorType property instead.

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

Note: This API is now obsolete. Use the SchedulerStorage.ReminderDstBehaviorType property instead

Expanded Syntax

Property value

Type: DstBehaviorType
One of the DstBehaviorType enumeration values.

Expanded Remarks

This property enables you to correct the reminder's behavior for a series of recurring appointments if an occurrence in a series falls in a DST shift (in the United States, it is the interval between 2:00:00 and 2:59:59 local time on the Daylight Saving Time start date, the time interval that actually doesn't exist). By default, the property is set to DstBehaviorType.AlertAfterDstShift and if the alert time falls in the DST shift, an alert is invoked at the end of the DST shift, i.e. at 3 AM in the United States.

To invoke the reminder alert at the specified time before the actual start of an appointment, set the DstBehavior property to the DstBehaviorType.Update value. The alert time will be updated as required.

To dismiss the reminder when it falls in the DST shift, use the DstBehaviorType.Dismiss property value.

Consider two scenarios with different settings for the DstBehavior property.

Scenario 1:

Appointment.Start = 2:05, ReminderBase.TimeBeforeStart = 6 min.

Value Behavior
DstBehaviorType.Dismiss the reminder will be dismissed
DstBehaviorType.AlertAfterDstShift the alert will be triggered at 3:00 AM.
DstBehaviorType.Update the alert will be triggered at 1:59 AM.

Scenario 2:

Appointment.Start = 2:30, ReminderBase.TimeBeforeStart = 6 min.

Value Behavior
DstBehaviorType.Dismiss the reminder will be dismissed
DstBehaviorType.AlertAfterDstShift the alert will be triggered at 3:24 AM.
DstBehaviorType.Update the alert will be triggered at 3:24 AM.
