I am showing a movie on my application, and i want the application to only play it once. And when its done playing i want to enable some buttons (play, rewind, watch again etc...) but is there any way i can get an event when the movie has finished - or anything that would accomplish this scenario?
Cheers,
The MediaElement.MediaEnded event should help you
