Hi, I am unable to populate the chapters using code-behind. What am I doing wrong? Playlist gets created but without chapters.

           var items = e.Result;
            ObservableCollection<RadMediaItem> itemsSource = new ObservableCollection<RadMediaItem>();

            foreach (OnlineTraining item in items)
            {
                RadMediaItem media = new RadMediaItem();
                media.Source = new Uri(item.FileName, UriKind.RelativeOrAbsolute);
                media.Title = item.Title;
                media.Description = item.Description;
                media.ImageSource = new System.Windows.Media.Imaging.BitmapImage(new Uri(item.ImageSource, UriKind.RelativeOrAbsolute));
                ObservableCollection<RadMediaChapter> mediachapter = new ObservableCollection<RadMediaChapter>();
                RadMediaChapter chapter = new RadMediaChapter();
                chapter.Position = "00:00:05";
                chapter.Title = "test";
                mediachapter.Add(chapter);

                 chapter = new RadMediaChapter();
                chapter.Position = "00:10:00";
                chapter.Title = "test2";
                mediachapter.Add(chapter);

                chapter = new RadMediaChapter();
                chapter.Position = "00:20:00";
                chapter.Title = "test2";
                mediachapter.Add(chapter);

                chapter = new RadMediaChapter();
                chapter.Position = "00:30:00";
                chapter.Title = "test2";
                mediachapter.Add(chapter);

                chapter = new RadMediaChapter();
                chapter.Position = "00:40:00";
                chapter.Title = "test2";
                mediachapter.Add(chapter);

                chapter = new RadMediaChapter();
                chapter.Position = "00:50:00";
                chapter.Title = "test2";
                mediachapter.Add(chapter);

                media.Items.Add(mediachapter);
                itemsSource.Add(media);

            }
            RadMediaPlayer1.ItemsSource = itemsSource;

Hello Martin,

The problem is where you say media.Items.Add(mediachapter); It means that you are adding a collection(ObservableCollection<RadMediaChapter> mediachapter) to the Items of media. Instead you should add each chapter to the Items of the media item:

foreach (OnlineTraining item in items)

{

RadMediaItem media = new RadMediaItem();

media.Source = new Uri(item.FileName, UriKind.RelativeOrAbsolute);

media.Title = item.Title;

media.Description = item.Description;

media.ImageSource = new System.Windows.Media.Imaging.BitmapImage(new Uri(item.ImageSource, UriKind.RelativeOrAbsolute));

RadMediaChapter chapter = new RadMediaChapter();

chapter.Position = "00:00:05";

chapter.Title = "test";

media.Items.Add(chapter);
