3.后台cs代码

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)
    {
        List<mydata> dt = new List<mydata>();
        for (int i = 0; i < 10; i++)
        {
            dt.Add(new mydata() { Name = i.ToString() + "key", Content = i.ToString() + "val" });
        }
        return dt;
    }
}

public class Group<S, T> : IEnumerable<T>
{
    public Group(S groupItem, IEnumerable<T> items)
    {
        this.GroupItem = groupItem;
        this.Items = new List<T>(items);
    }

    public override bool Equals(object obj)
    {
        Group<S, T> other = obj as Group<S, T>;
        return (other != null) && (GroupItem.Equals(other.GroupItem));
    }
    public override int GetHashCode()
    {
        return GroupItem.GetHashCode();
    }

    public S GroupItem { get; set; }
    public IList<T> Items { get; set; }

    public IEnumerator<T> GetEnumerator()
    {
        return Items.GetEnumerator();
    }

    System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator()
    {
        return Items.GetEnumerator();
    }
}

public class mydata
{
    public string Name { get; set; }
    public string Content { get; set; }
}
