CollectionViewSource.DeferRefresh Method

Enters a defer cycle that you can use to merge changes to the view and delay automatic refresh.

Namespace:  System.Windows.Data
Assembly:  PresentationFramework (in PresentationFramework.dll)

member DeferRefresh : unit -> IDisposable

Return Value

Type: System.IDisposable
An IDisposable object that you can use to dispose of the calling object.

The typical usage is to create a using scope with this method and then place multiple view-changing calls within the scope. This delays automatic refresh until the defer cycle is exited.
