I have a "Slide-Show" application that displays both images (Ads) and video (commercials). I use an Image control and a MediaElement control to show the content. Both are controlled with storyboards to animate in and out of each image or video. I saw the RadTransitionControl and I liked what I saw but am not quite sure how to use it in this scenario. Can I have the two controls in the DataTemplate? If so how does it know which one to show at the moment? Or do I need to change "Opacity" or "Visibility" on the individual controls in the TransitionControl before the animation fires?
