How to: Animate an Object Along a Path (Point Animation)
This example shows how to use a xref:System.Windows.Media.Animation.PointAnimationUsingPath object to animate a xref:System.Windows.Point along a curved path.
Example
The following example moves an xref:System.Windows.Media.EllipseGeometry along a path defined by a xref:System.Windows.Media.PathGeometry. The ellipse geometry's xref:System.Windows.Media.EllipseGeometry.Center%2A property, which takes a xref:System.Windows.Point value, specifies its position; to move the ellipse geometry, you animate its xref:System.Windows.Media.EllipseGeometry.Center%2A property. The example uses a xref:System.Windows.Media.Animation.PointAnimationUsingPath to animate the xref:System.Windows.Media.EllipseGeometry object's xref:System.Windows.Media.EllipseGeometry.Center%2A property.

For the complete sample, see Path Animation Sample.
The code version of the preceding sample used a xref:System.Windows.Media.Animation.Storyboard to animate the xref:System.Windows.Media.EllipseGeometry, even though only one animation was applied. A xref:System.Windows.Media.Animation.Storyboard is often the easiest way to apply multiple animations because these animations can be controlled by the same xref:System.Windows.Media.Animation.Storyboard. However, an easier way to apply a single animation to a property when using code is to use the xref:System.Windows.Media.Animation.Animatable.BeginAnimation%2A method. For an example, see Animate a Property Without Using a Storyboard.
