We are currently developing a new version of RadCoverFlow that supports UIElements, Images and Videos out of the box.
For example, you will be able to set the ItemsSource to a collection of Videos, or Images that will be loaded and played by the RadCoverFlow automatically. Moreover, we have simplified the use of the control, thus its API will be significantly changed. Due to the major changes introduced in the new control, we plan to release a beta version of the control along with several other new controls that are being developed right know. Unfortunately I cannot share any information concerning these new controls. The beta version should be available until the end of September. However, it's possible to postpone it and to release final version of these new controls for Q3.
Thank you for contacting us and we look forward to answering more of your questions.
