一、DataGrid分组

　　在Silverlight的表格中可能需要对某一些数据进行分组以方便客户查看，我们使用PagedCollectionView集合作为数据源，然后通过设置其GroupDescriptions属性值，添加需要分组的实体集合属性，注意：如果需要两层分组则添加两个属性即可。

　　Xaml代码：

　　Xaml.cs代码如下：

PagedCollectionView view = new PagedCollectionView(CityInfo.GetInfo());            //此处根据AddrName属性分组            view.GroupDescriptions.Add(new PropertyGroupDescription("AddrName"));            //如果需要多重分组，则取消以下注释            //view.GroupDescriptions.Add(new PropertyGroupDescription("CityName"));            this.ShowCityList.ItemsSource = view;

　　实体数据源函数如下：

public static List
      
        GetInfo()        {            var list = new List
       
        ();            list.Add(new CityInfo() { AddrName = "北京", CityName = "北京市", TelNum = "010" });            list.Add(new CityInfo() { AddrName = "上海", CityName = "上海市", TelNum = "020" });            list.Add(new CityInfo() { AddrName = "广东", CityName = "广州市", TelNum = "021" });            list.Add(new CityInfo() { AddrName = "广东", CityName = "深圳市", TelNum = "0210" });            list.Add(new CityInfo() { AddrName = "四川", CityName = "成都市", TelNum = "028" });            list.Add(new CityInfo() { AddrName = "四川", CityName = "内江市", TelNum = "0832" });            list.Add(new CityInfo() { AddrName = "四川", CityName = "自贡市", TelNum = "0831" });            return list;        }

　　效果如下：

二、模拟合并单元格

　　在本实例中我们通过对数据源进行构造，然后在DataGrid控件上设置DataGridTemplateColumn的模板方式模拟合并单元格。

　　Xaml代码：

　　Xaml.cs代码：

this.ShowCity.ItemsSource = CityInfo.GetInfoList();

　　实体数据源函数如下：

public static List
      
        GetInfoList()        {            var list = new List
       
        ();            list.Add(new CityInfo() { AddrName = "北京", CityNames = new List
        
         () { "北京市" },                TelNums = new List
         
          () { "010" } });            list.Add(new CityInfo() { AddrName = "上海", CityNames = new List
          
           () { "上海市" },                TelNums = new List
           
            () { "020" } }); list.Add(new CityInfo() { AddrName = "广东", CityNames = new List
            
             () { "广州市", "深圳市" }, TelNums = new List
             
              () { "021","0210" } }); list.Add(new CityInfo() { AddrName = "四川", CityNames = new List
              
               () { "成都市", "内江市","自贡市" }, TelNums = new List
               
                () { "028","0832","0831" } }); return list; }

　　效果如下：

三、实体类如下：

///     /// 城市信息的实体类    ///     public class CityInfo    {        private string _AddrName;        private string _CityName;        private string _TelNum;        public string AddrName        {            get { return _AddrName; }            set { _AddrName = value; }        }        public string CityName        {            get { return _CityName; }            set { _CityName = value; }        }        public string TelNum        {            get { return _TelNum; }            set { _TelNum = value; }        }        private List
      
        _CityNames;        public List
       
         CityNames        {            get { return _CityNames; }            set { _CityNames = value; }        }        private List
        
          _TelNums;        public List
         
           TelNums        {            get { return _TelNums; }            set { _TelNums = value; }        }}
