[Omid reza]

i want to create a ranking panel for a race , but when in first time i bind my collection to my radtileview it's work correctly , but after it , if i change one of the attributes , like name , position and etc , does not make any change in radtileview.

public class pool
    {
        public string _name;
        public string name
        {
            get{return _name;}
            set { _name = value; }
        }
        public int _position;
        public int position
        {
            get { return _position; }
            set { _position = value; }
        }
    }

    public partial class MainPage : UserControl
    {
        ObservableCollection<pool> p;
        public MainPage()
        {
            InitializeComponent();

            p = new ObservableCollection<pool>();
            for (int i = 0; i < 100; i++)
            {
                pool pn = new pool();
                pn.name = "name: " + i.ToString();
                p.Add(pn);
            }
            tile1.ItemsSource = p;
            tile1.Height = 30 * 102;
            p[2].position += 7;
        }

        private void Button_Click(object sender, System.Windows.RoutedEventArgs e)
        {
            p[2].position += 4;
        }
    }

Hi Omid reza,

 You should make your classes implement the INotifyPropertyChanged interface in order to update the UI automatically.
