PlaylistManagement [C#]

This example shows how to retrive groups playlists and medias from specific manager, and how to add a new media to playlist.

[C#]

    
   //Initialize the XAML object and retrieve group from server by login 
   public PlaylistManagement(string login, string password) 
   { 
       InitializeComponent(); 
  
       //Login and retrive group 
       List<View_Group> listResult; 
       sample.GetGroup(out listResult, login, password); 
  
       //Bind group to tree 
       treeGroup.ItemsSource = TreeNode.GetTreeNode(listResult); 
   } 


 

[C#]

    
   //Select group and retrive coresponding medias and playlist 
   private void treeGroup_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e) 
   { 
       //Get Medias for specific group 
       List<View_Media> listMediaResult; 
       sample.GetMedia(out listMediaResult, (treeGroup.SelectedItem as TreeNode).Id??0); 
  
       //Update media thumbnail path 
       listMediaResult.ForEach(x => x.ThumbnailPath = (x.ThumbnailPath != null) ? (GlobalParam.MEDIA_URL + x.ThumbnailPath) : ""); 
  
       //Bind media to List 
       gridMedia.ItemsSource = listMediaResult; 
  
  
       //Get Playlist for specific group 
       List<View_Playlist> listPlaylistResult; 
       sample.GetPlaylist(out listPlaylistResult, (new long[] {(treeGroup.SelectedItem as TreeNode).Id ?? 0}).ToList()); 
  
       //Bind playlist to List 
       gridPlaylist.ItemsSource = listPlaylistResult; 
   } 


 

[C#]

    
   //Select playlist and retrive coresponding playlist medias 
   private void gridPlaylist_SelectionChanged(object sender, SelectionChangedEventArgs e) 
   { 
       if (gridPlaylist.SelectedItem == null) return; 
  
       //Get Playlist media from selected playlist 
       List<View_PlaylistComponent> listResult; 
       sample.GetPlaylistMedia(out listResult, (treeGroup.SelectedItem as TreeNode).Id ?? 0, (gridPlaylist.SelectedItem as View_Playlist).Id); 
  
       //Update media thumbnail path 
       listResult.ForEach(x => x.ThumbnailPath = (x.ThumbnailPath != null) ? (GlobalParam.MEDIA_URL + x.ThumbnailPath) : ""); 
  
       //Bind media to List 
       gridPlComponent.ItemsSource = new ObservableCollection<View_PlaylistComponent>(listResult); 
   } 


 

[C#]

    
   //Drop media to playlist 
   private void gridPlComponent_Drop(object sender, DragEventArgs e) 
   { 
       if (gridPlaylist.SelectedItem == null) return;

       ListBox box = (ListBox)sender; 
       ObservableCollection<View_PlaylistComponent> list = (box.ItemsSource as ObservableCollection<View_PlaylistComponent>); 
        
       //Retrive media to drop 
       View_Media media = e.Data.GetData(typeof(View_Media)) as View_Media; 
  
       //Get media position 
       Point pnt = e.GetPosition(box); 
       ScrollViewer scroll = VisualTreeHelper.GetChild(VisualTreeHelper.GetChild(box, 0), 0) as ScrollViewer; 
       int position = Math.Min(list.Count, (int)(scroll.VerticalOffset + (pnt.Y / 48))); 
  
       //Create playlist media data 
       View_PlaylistComponent component = new View_PlaylistComponent() 
           { 
               //Active = media.Active, 
               //Duration = media.Duration, 
               //HideBanner = media.HideBanner, 
               ManagerIdAddedBy = media.ManagerIdAddedBy, 
               MediaId = media.Id, 
               MediaName = media.Name, 
               //MediaPath = media.MediaPath, 
               NoBanner = true, 
               Order = position, 
               //PeriodCount = media.periodCount ?? 0, 
               PlaylistId = (gridPlaylist.SelectedItem as View_Playlist).Id, 
               ThumbnailPath = media.ThumbnailPath, 
               TypeId = 1 
           }; 
  
       //Add playlist media 
       sample.AddPlaylistMedia(ref component, (treeGroup.SelectedItem as TreeNode).Id ?? 0); 
        
       //Insert result in the collection 
       list.Insert(position, component);
