ThicknessAnimationBase Class
Visual Studio 2008
Abstract class that, when implemented, animates a Thickness value.
Assembly: PresentationFramework (in PresentationFramework.dll)
Notes to Inheritors:
See the Custom Animations Overview for information about extending animation classes.
The following code example demonstrates how to use the derived ThicknessAnimationUsingKeyFrames class in Extensible Application Markup Language (XAML).
