WPF ListView Display Cascading information

Usually we show a list of similar data in the ListView, such as the city name. However, the datatemplate of the ListView can be modified slightly to show cascading information. For example, you need to display the city name of the province and province in the ListView. First prepare the base class,

City class:

    public class City:viewmodebase    {        private string _name;        public string Name        {            get            {                return _name;            }            Set            {                if (_name! = value)                {                    _name = value;                    OnPropertyChanged ("Name");}}}    

Province class:

    public class Province:viewmodebase    {        private string _name;        public string Name        {            get            {                return _name;            }            Set            {                if (_name! = value)                {                    _name = value;                    OnPropertyChanged ("Name");        }}} Private observablecollection<city> _citys;        Public observablecollection<city> citys        {            get            {                return _citys;            }            Set            {                if (_citys! = value)                {                    _citys = value;                    OnPropertyChanged ("Citys");        }}} Public province ()        {            _citys = new observablecollection<city> ();        }    }

Making simulation data:

        Observablecollection<province> _provinces = null;            Public MainWindow () {InitializeComponent ();            Province Provincejs = new province () {Name = "Jiangsu"};            PROVINCEJS.CITYS.ADD (New city () {Name = "nanjing"});            PROVINCEJS.CITYS.ADD (New city () {Name = "Suzhou"});            PROVINCEJS.CITYS.ADD (New city () {Name = "wuxi"});            PROVINCEJS.CITYS.ADD (New city () {Name = "Changzhou"});            PROVINCEJS.CITYS.ADD (New city () {Name = "Zhenjiang"});            PROVINCEJS.CITYS.ADD (New city () {Name = "Taizhou"});            PROVINCEJS.CITYS.ADD (New city () {Name = "Nantong"});            Province Provincezj = new province () {Name = "Zhejiang"};            PROVINCEZJ.CITYS.ADD (New city () {Name = "Hangzhou"});            PROVINCEZJ.CITYS.ADD (New city () {Name = "Ningbo"});            PROVINCEZJ.CITYS.ADD (New city () {Name = "Wenzhou"});            PROVINCEZJ.CITYS.ADD (New city () {Name = "jiaxing"});      PROVINCEZJ.CITYS.ADD (New city () {Name = "Huzhou"});      PROVINCEZJ.CITYS.ADD (New city () {Name = "Shaoxing"});            PROVINCEZJ.CITYS.ADD (New city () {Name = "Jinhua"});            PROVINCEZJ.CITYS.ADD (New city () {Name = "Quzhou"});            Province provincesd = new province () {Name = "Shandong"};            PROVINCESD.CITYS.ADD (New city () {Name = "Jinan"});            PROVINCESD.CITYS.ADD (New city () {Name = "Weifang"});            PROVINCESD.CITYS.ADD (New city () {Name = "Taian"});            _provinces = new observablecollection<province> (); _provinces.            ADD (Provincejs); _provinces.            ADD (PROVINCEZJ); _provinces.            ADD (PROVINCESD);        DataContext = _provinces; }
