MediaManagement [C#]

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

[C#]

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


 

[C#]

    
   //Select a group and retrive coresponding medias 
   private void treeGroup_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e) 
   { 
       //Get Medias for selected group 
       List<View_Media> listResult; 
       sample.GetMedia(out listResult, (treeGroup.SelectedItem as TreeNode).Id ?? 0); 
  
       //Update media thumbnail path 
       listResult.ForEach(x => x.ThumbnailPath = (x.ThumbnailPath != null) ? (GlobalParam.MEDIA_URL + x.ThumbnailPath) : ""); 
  
       //Bind media to List 
       gridMedia.ItemsSource = new ObservableCollection<View_Media>(listResult); 
   }
