Change Source in MediaElement (SILVERLIGHT)

Question

I would like to change song on my MediaElent from track1.mp3 to track2.mp3. And here is the code:

MyMediaElement.Stop();
Uri u = new Uri("track2.mp3", UriKind.Relative);
MyMediaElement.Source=u;
MyMediaElement.Play();

The MediaElement change the source but just wont start. What could possibly be wrong with this code?

Answer 1

You don't appear to be doing anything wrong. Here are a couple of diagnostics I would try:-

Specify track2 as the initial file does that work?

Attach to the MediaFailed event, does that get fired?

Bind a TextBlock to the CurrentState property to observe how the CurrentState has changed.

Answer 2

Try setting MyMediaElement.AutoPlay to true, as soon as the source changes it should play. You could also investigate using the MediaElement.SetSource() method which takes a stream rather than a uri.

Answer 3

I had the same problem. I could set autoplay and the source in the XAML and it would work, but if I changed source in the code it would just do nothing.
I captured the MediaOpened event of the control.
The problem is that it hits Play() right after you changed the source, so the current state is closed. It takes a few clock cycles to change the state. So, if you put Play(); inside that event handler it will work.
