UIElement.InvalidateArrange Method

Invalidates the arrange state (layout) for the element. After the invalidation, the element will have its layout updated, which will occur asynchronously unless subsequently forced by UpdateLayout.

Namespace: System.Windows
Assembly: PresentationCore (in presentationcore.dll)

'Declaration
Public Sub InvalidateArrange
'Usage
Dim instance As UIElement

instance.InvalidateArrange
public void InvalidateArrange ()
public function InvalidateArrange ()
You cannot use methods in XAML.

Frequent calls to InvalidateArrange or in particular to UpdateLayout have significant performance consequences. Therefore, avoid calling this method unless you absolutely require precise layout state for subsequent calls to other APIs in your code. An advanced scenario where you might call InvalidateArrange is if you are creating a PropertyChangedCallback for a dependency property that is not on a Freezable or FrameworkElement derived class that still influences the arrange pass of layout when it changes.
