StringAnimationBase Class

Abstract class that, when implemented, animates a String value.

Namespace:  System.Windows.Media.Animation
Assembly:  PresentationCore (in PresentationCore.dll)
public abstract class StringAnimationBase : AnimationTimeline
This class is abstract; see Inheritance Hierarchy for derived non-abstract classes usable in XAML.

Notes to Inheritors:

See the Custom Animations Overview for information about extending animation classes.

The following code example demonstrates how to use the derived StringAnimationUsingKeyFrames class in Extensible Application Markup Language (XAML).

<!-- Demonstrates the StringAnimationUsingKeyFrames class. A StringAnimationUsingKeyFrames is used to
   animate the TextContent property of a Text element. -->
