Andy Beaulieu demonstrates how to use PathListBox for some interesting effects.
The PathListBox control is a cool new addition to the Blend 4 SDK, and allows the elements inside a ListBox to lay out along any Path control shape. You’ll need to install the Blend 4 SDK to get access to the PathListBox control, but note that this is available outside of Expression Blend 4 (you don’t need to purchase or install Blend 4).
One of the neat bonus features of the PathListBox is that you can animate the Path that it is bound to, and the items will follow the animation! This gives Silverlight functionality similar to the AnimationUsingPath class that WPF has had since .NET 3.0, and provides basic Motion Path Animation.
