currentAudio = event.target.selectedItem as AudioItem;
mediaPlayer.source = currentAudio.source;
This works fine, however what I don't know how to do, is dispatch a change event in response to an event other than the mouse event, as shown above. For starters, I'd like to dispatch an event in response to the VideoPlayer's "complete" event, which will increment the selectedIndex by one, in which case I imagine a variation of the code above will work to achieve the desired effect and play the next item. Some advice on approaching this type of change event would be greatly appreciated.
