I am using Slider control for audio player in silverlight 3.0 application. I can do forward and backward the slider.The problem is the slider is not moving automatically even the audio is playing. How to get it??

Sounds to me that you don't have TwoWay binding set up. In you binding statement, use Mode=TwoWay. Maybe I'm not completely understanding your question, but that's the first thing I would look at.
