SchedulerStorage.BeginUpdate() Method

Locks the SchedulerStorage, preventing visual updates of the object and its elements until the EndUpdate or CancelUpdate method is called.

Namespace: DevExpress.Xpf.Scheduler

Assembly: DevExpress.Xpf.Scheduler.v20.1.dll

Declaration

public void BeginUpdate()
Public Sub BeginUpdate

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.

Call the BeginUpdate method to maintain performance while applying multiple modifications to the object. After the BeginUpdate method the IsUpdateLocked property returns false to prevent other processes from modifying the object or retrieving its properties. After applying all modifications, call the EndUpdate or CancelUpdate method to finalize the update or cancel it.

Each call to BeginUpdate must be paired with a call to EndUpdate or CancelUpdate. To ensure that EndUpdate/CancelUpdate is always called even if an exception occurs, enclose them in the try...finally statement.
