SchedulerStorage.AppointmentCollectionAutoReloading Event

Occurs when the data source which contains appointment records is modified, and appointments are set to be automatically reloaded.

Namespace:DevExpress.Xpf.Scheduler
Assembly:DevExpress.Xpf.Scheduler.v19.2.dll

Expanded Syntax

Expanded Event Data

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

Expanded Remarks

Important

You are viewing documentation for the legacy WPF Scheduler control. If you're starting a new project, we strongly recommend that you use a new control declared in the DevExpress.Xpf.Scheduling namespace. If you decide to upgrade an existing project in order to switch to the updated scheduler control, see the Migration Guidelines document.

In bound mode, the SchedulerStorage object is bound to a data source which contains appointment records. This data source is specified by the DataMember and DataSource properties of the AppointmentStorage object.

When the AutoReload property of the AppointmentStorage object is set to true, the data is automatically reloaded. In this case, the SchedulerStorage object reloads data from the data source each time an item in the data source is modified, added, moved or removed, a column is added, modified or deleted or multiple changes are made to the data source. The AppointmentCollectionAutoReloading event allows you to prevent data from being reloaded in specific cases. Use the event's ListChangedType parameter to get the cause of the data source changes. To prevent data from being reloaded in a specific case, set the DevExpress.XtraScheduler.CancelListChangedEventArgs.Cancel parameter to true. Otherwise, the SchedulerStorage object will reload data from the data source immediately after the event handler is completed.

The AppointmentCollectionAutoReloading event doesn't fire in unbound mode and in bound mode if the AppointmentStorage.AutoReload property is set to false.

Expanded Example

In the following example, the AppointmentCollectionAutoReloading and ResourceCollectionAutoReloading events are handled to prevent appointments and appointment Resources from being reloaded from a data source in the following cases:

  • When a data source item (row) is being moved to a new position.
  • When a column (field) is added, modified or deleted in the data source.
