示例中,在实际应用中,有时候ListBox item可能是不同的,
比如日程管理小程序,如果用一个ListBox item表示一天的日程,那一个item可能有一个日程安排,有可能有多个日程安排,也有可能是没有日程安排。
这时候我们可以用ItemsControl作为ListBox item,
即列表中嵌入列表。

首先,我们在页面放置一个ListBox,通过ListBox.ItemTemplate,设置每一个item的visual样式。
这里ListBox的Item是一个ItemsControl,ItemsContol顾名思义,它类似ListBox,也是一个列表。

在我们示例中,通过ObservableCollection<ShowDataList> showDatas为ListBox提供数据。
通过ShowDataList为ItemsControl提供数据,通过Data绑定为ItemsControl中每一个Item提供数据。
具体实现代码如下:
Code:
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;

namespace PhoneApp2
{
    public partial class MainPage : PhoneApplicationPage
    {
        public ObservableCollection<ShowDataList> showDatas { get; set; }

        // 构造函数
        public MainPage()
        {
            InitializeComponent();

            showDatas = new ObservableCollection<ShowDataList>
            {
                new ShowDataList()
                { 
                    DataList= new List<Data>
                    {
                    new Data{date = "星期2 7月21号", name = "abd", image = "/Interface;component/Images/Show/default_2.jpg", detail= "ddsssss"},
                    new Data{date = "星期2 7月21号", name = "ccv", image = "/Interface;component/Images/Show/default_2.jpg", detail= "gssde"}
                    }
                },
                new ShowDataList()
                {
                    DataList= new List<Data>
                    {
                    new Data{date = "星期3 7月21号", name = "abd", image = "/Interface;component/Images/Show/default_2.jpg", detail= "ddsssss"},
                    new Data{date = "星期3 7月21号", name = "ccv", image = "/Interface;component/Images/Show/default_2.jpg", detail= "gssde"},
                    new Data{date = "星期3 7月21号", name = "ccv", image = "/Interface;component/Images/Show/default_2.jpg", detail= "gssde"}
                    }                
                }
            };

            mainList.ItemsSource = showDatas;
        }
    }

    public class ShowDataList
    {
        public List<Data> DataList { get; set; }
    }

    public class Data
    {
        public String date { get; set; }
        public String image { get; set; }
        public String name { get; set; }
        public String detail { get; set; }
    }

}
