Property Value

Type	Description
TimeSpan	A TimeSpan structure which is an interval before the appointment’s start time. Default is 15 minutes.

Remarks

Use the TimeBeforeStart property to specify a period of time before the appointment’s start when you should be reminded. The alert time is calculated using the following formula: ReminderBase.AlertTime = Appointment.Start - ReminderBase.TimeBeforeStart.

Changing the TimeBeforeStart property’s value raises the ReminderBase.RemindTimeChanged event.

Note

The default value of the TimeBeforeStart property is 15 minutes.
