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

Assembly:  PresentationFramework (in PresentationFramework.dll)

public virtual bool NeedsRefresh { get; }
You cannot set this property in XAML.

Property Value

Type: System.Boolean
true if the view needs to be refreshed; otherwise, false.

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.
