I am glad to hear you are making progress. Please also refer to our Silverlight/WPF Automation section
where you can find more information on how to search and validate Silverlight/WPF elements and how to perform actions upon them. That section also includes a sample automation scenario against simple WPF app
that should be enough to get you started.
Please go through our online documentation
and let me know if you need any assistance to cover a specific WPF automation scenario.
All the best,
the Telerik team
