Public Property RemindersCheckInterval As Integer
| Type | Default | Description |
|---|---|---|
| Int32 | 15000 |
An integer value which represents the time interval between checks of the reminder’s alert.

By default all reminder alerts are checked by the scheduler storage every 15 seconds (15000 milliseconds), but your reminders can be checked more or less frequently. Set the RemindersCheckInterval property to another time interval value.
The following example demonstrates how to manually handle reminders and perform a custom action when the SchedulerStorageBase.ReminderAlert event is fired.
// Handle this event to perform a custom action when a reminder alert is fired.
schedulerStorage1.ReminderAlert += SchedulerStorage1_ReminderAlert;
// Specify the interval at which the reminder is polled for alert.
schedulerStorage1.RemindersCheckInterval = checkInterval * 1000;
// Hide the reminder alert window.
schedulerControl1.OptionsBehavior.ShowRemindersForm = false;
private void SchedulerStorage1_ReminderAlert(object sender, ReminderEventArgs e) {
// Create a new appointment.
Appointment app = schedulerStorage1.CreateAppointment(AppointmentType.Normal);
app.Subject = "Created on alert from appointment w/Price = " + e.AlertNotifications[0].ActualAppointment.CustomFields["CustomPrice"];
app.Start = e.AlertNotifications[0].ActualAppointment.Start.AddHours(2);
app.Duration = TimeSpan.FromHours(4);
schedulerStorage1.Appointments.Add(app);
// Modify the appointment for which the alert is triggered.
e.AlertNotifications[0].ActualAppointment.LabelKey = 3;
// Prevent the event from being fired one more time.
e.AlertNotifications[0].ActualAppointment.Reminder.Dismiss();
}
' Handle this event to perform a custom action when a reminder alert is fired.
AddHandler schedulerStorage1.ReminderAlert, AddressOf SchedulerStorage1_ReminderAlert
' Specify the interval at which the reminder is polled for alert.
schedulerStorage1.RemindersCheckInterval = checkInterval * 1000
' Hide the reminder alert window.
schedulerControl1.OptionsBehavior.ShowRemindersForm = False
Private Sub SchedulerStorage1_ReminderAlert(ByVal sender As Object, ByVal e As ReminderEventArgs)
' Create a new appointment.
Dim app As Appointment = schedulerStorage1.CreateAppointment(AppointmentType.Normal)
app.Subject = "Created on alert from appointment w/Price = " + e.AlertNotifications(0).ActualAppointment.CustomFields("CustomPrice").ToString()
app.Start = e.AlertNotifications(0).ActualAppointment.Start.AddHours(2)
app.Duration = TimeSpan.FromHours(4)
schedulerStorage1.Appointments.Add(app)
' Modify the appointment for which the alert is triggered.
e.AlertNotifications(0).ActualAppointment.LabelKey = 3
' Prevent the event from being fired one more time.
e.AlertNotifications(0).ActualAppointment.Reminder.Dismiss()
End Sub
