I believe you wish to create a wizard with RadWindow. Please, use the resources posted earlier in this thread to see an example of how this can be done.
Please note, however, that this is an old example and RadPage, RadFrame and RadFrameContainer are no longer supported. Instead, you can use the Silverlight 4 Navigation framework which provides paged navigation for the same purposes. Please, check this helpful MSDN article
on the topic.
I believe switching to Silverlight 4 navigation will be easy enough. However, if you need more help on this subject, let me know.
