[Solved] Media Player Ended increment Cover flow selected index

[Pawan Venugopal]

Hi ,

       I have a media player which plays when the coverflow is clicked. what i am trying to achieve is that once the video of the cover flow is ended i need to hide the video player increment the cover flow element by + 1 and start playing the next video corresponding to that cover flow element.  Can you show me a sample of how to achieve this.  this is the code which i used to increment the selected index of the cover flow element. But i am not sure how to play the video again.

        public bool IsSelected

        {

            get { return (bool)GetValue(IsSelectedProperty); }

            set { SetValue(IsSelectedProperty, value); }

        }

        public static readonly DependencyProperty IsSelectedProperty = DependencyProperty.Register("IsSelected", typeof(bool), typeof(VideoPlayer), new PropertyMetadata(OnIsSelectedChange));

        private static void OnIsSelectedChange(DependencyObject d, DependencyPropertyChangedEventArgs args)

        {

            if ((bool)args.NewValue)

            {

                (d as VideoPlayer).ShowMediaPlayer();

            }
