There’s an official sample for SemanticZoom control, but it’s overly difficult to learn with complicated data struct. So this sample will show you how to bind simple data to a SemanticZoom control. Besides, this sample is based on Matt Small’s blog:
You can find more code samples that demonstrate the most typical programming scenarios by using Microsoft All-In-One Code Framework Sample Browser or Sample Browser Visual Studio extension. They give you the flexibility to search samples, download samples on demand, manage the downloaded samples in a centralized place, and automatically be notified about sample updates. If it is the first time that you hear about Microsoft All-In-One Code Framework, please watch the introduction video on Microsoft Showcase, or read the introduction on our homepage http://1code.codeplex.com/.
