See the Custom Animations Overview for information about extending animation classes.
The following code example demonstrates how to use the derived ColorAnimationUsingKeyFrames class using Extensible Application Markup Language (XAML).

LinearColorKeyFrame creates a smooth, linear animation between values. --> <LinearColorKeyFrame Value="Red" KeyTime="0:0:2" /> <!-- In the next half second, go to yellow. DiscreteColorKeyFrame creates a sudden jump between values. --> <DiscreteColorKeyFrame Value="Yellow" KeyTime="0:0:2.5" /> <!-- In the final 2 seconds of the animation, go from yellow back to green. SplineColorKeyFrame creates a variable transition between values depending on the KeySpline property. In this example, the animation starts off slow but toward the end of the time segment, it speeds up exponentially.--> <SplineColorKeyFrame Value="Green" KeyTime="0:0:4.5" KeySpline="0.6,0.0 0.9,0.00" /> </ColorAnimationUsingKeyFrames.KeyFrames> </ColorAnimationUsingKeyFrames> </Storyboard> </BeginStoryboard> </EventTrigger> </Border.Triggers> <TextBlock> This example shows how to use the ColorAnimationUsingKeyFrames to create an animation on the BorderBrush property of a Border. </TextBlock> </Border> </StackPanel> </Page>
