CollectionView.NeedsRefresh Property

Definition

Namespace:

System.Windows.Data

Assembly:

PresentationFramework.dll

Gets a value that indicates whether the view needs to be refreshed.

public:
 virtual property bool NeedsRefresh { bool get(); };

public virtual bool NeedsRefresh { get; }

member this.NeedsRefresh : bool

Public Overridable ReadOnly Property NeedsRefresh As Boolean

Property Value

Boolean

true if the view needs to be refreshed; otherwise, false.

Remarks

This property indicates if the internal state of the view has changed and requires a Refresh method call. The typical scenario is if a SortDescription or similar has been added to the view while the view is in a deferred refresh cycle (see DeferRefresh). In this scenario, no explicit call to Refresh is needed; as soon as the deferred refresh cycle ends, the view calls refresh automatically.
