Invalidates the rendering of the element, and forces a complete new layout pass. OnRender is called after the layout cycle is completed.
Public Sub InvalidateVisual
Dim instance As UIElement instance.InvalidateVisual()
public void InvalidateVisual()
public: void InvalidateVisual()
public function InvalidateVisual()
You cannot use methods in XAML.
This method calls InvalidateArrange internally.
This method is not generally called from your application code. The WPF framework-level layout system does its own handling of changes in the visual tree of an element, and would be calling the equivalent of this method when necessary already. Calling this method is necessary only for advanced scenarios. One such advanced scenario 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 layout when it changes.
