public partial class MainPage : PhoneApplicationPage
{
    // Constructor
    public MainPage()
    {
        InitializeComponent();
        Loaded += new RoutedEventHandler(MainPage_Loaded);
        LongList.SelectionChanged += new SelectionChangedEventHandler(LongList_SelectionChanged);
    }

    void LongList_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        if (LongList.SelectedItem != null)
        {
            var d = LongList.SelectedItem as mydata;
            if (d != null)
            {

            }
        }
    }

    void MainPage_Loaded(object sender, RoutedEventArgs e)
    {
        List<Group<string, mydata>> dt = new List<Group<string, mydata>>();
        for (int i = 0; i < 10; i++)
        {
            dt.Add(new Group<string, mydata>(i.ToString(), getContent(i)));
        }
        LongList.ItemsSource = dt;
    }

    IEnumerable<mydata> getContent(int k)
    {

        for (int i = 0; i < 10; i++)
        {

        }
        return dt;
    }
}

public class Group<S, T> : IEnumerable<T>

    }

    public override bool Equals(object obj)

    public IEnumerator<T> GetEnumerator()
    {

    }

    System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator()

public class mydata
