Remarks

The SchedulerStorageBase.AppointmentCollectionAutoReloading and SchedulerStorageBase.ResourceCollectionAutoReloading events occur before a SchedulerStorage starts to automatically reload appointments or resources data after changes have been made to the bound datasource. Since in some cases, such reloading can be time-consuming it can be cancelled by setting the CancelListChangedEventArgs.Cancel property to true.

An instance of the CancelListChangedEventArgs class with appropriate settings is automatically created and passed to the corresponding event’s handler.
