SchedulerDataStorage.ReminderAlert Event

Occurs when a reminder alert is invoked.

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

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type ReminderEventArgs containing data related to this event.

The following ReminderEventArgs properties provide information specific to this event.
Property Description
AlertNotifications Gets any reminders currently triggered.

Expanded Remarks

The XtraScheduler control supports reminders for appointments. A reminder can be invoked a specific time period before an appointment's start time. When the reminder alerts, the ReminderAlert event fires. Handle this event to perform specific actions when a reminder is activated. For instance, play a sound or post specific data to a database server, etc.

Note that multiple reminders can raise at the same time. To get these reminders use the event's DevExpress.XtraScheduler.ReminderEventArgs.AlertNotifications parameter. It holds a collection of notifications represented by DevExpress.XtraScheduler.ReminderAlertNotification objects. Each notification refers to the associated reminder and has a DevExpress.XtraScheduler.ReminderBaseAlertNotification.Handled property. Setting the Handled property to true indicates that this particular reminder is handled and that no default processing is required. For instance, you can postpone a reminder via the DevExpress.XtraScheduler.ReminderBase.Snooze method and then set the Handled property to true. In this case, the reminder will not be affected after completion of your event handler processing. If the Handled property is false, the reminder will be automatically switched off via the DevExpress.XtraScheduler.ReminderBase.Dismiss method.

If the DevExpress.XtraScheduler.SchedulerOptionsBehaviorBase.ShowRemindersForm property is true, a notification form is displayed when a reminder is invoked. Before the form is displayed, the SchedulerControl.RemindersFormShowing event is raised, and this allows you to display a custom form instead of a standard one.

Expanded Example

The following example demonstrates how to manually handle reminders and perform a custom action when the DevExpress.XtraScheduler.SchedulerStorageBase.ReminderAlert event is fired.
