WPF绑定复杂对象

我有一个模型实现如下所示的INotifyPropertyChanged。将名称和城市绑定到标签很容易。但是我在将玩家绑定到数据网格时遇到了问题。有没有人有任何提示？（这是所有只读信息。）WPF绑定复杂对象

public class Team : INotifyPropertyChanged 
{ 
    private string _name; 
    private string _city; 
    private List<Player> _players; 

    public string Name 
    { 
     get { return _name; } 
    } 

    public string City 
    { 
     get { return _city; } 
    } 

    public List<Player> Players 
    { 
     get { return _players; } 
    } 

} 
public class Player 
{ 
    public int ID {get; set;} 
    public string FirstName {get; set;} 
    public string LastName {get; set;} 
}

请为你的'DataGrid'显示你的XAML代码。你有什么尝试？ – devuxer

你无法编译这个，我编辑了你的代码，看到我的答案 – Coding4Fun

谁知道我以为我在做什么。但它现在正在工作。这里是的ItemSource：

ItemsSource="{Binding Path=Players}"

改变你的团队类，则必须执行INotifyPropertyChanged这样的：

public class Team : INotifyPropertyChanged 
    { 
     private string _name; 
     private string _city; 
     private List<Player> _players; 

     public string Name 
     { 
      get { return _name; } 
     } 

     public string City 
     { 
      get { return _city; } 
     } 

     public List<Player> Players 
     { 
      get { return _players; } 
      set { 
       _players =value; 
       RaisePropertyChanged("Players"); 
      } 
     } 


     #region INotifyPropertyChanged 

     internal void RaisePropertyChanged(string prop) 
     { 
      if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(prop)); } 
     } 
     public event PropertyChangedEventHandler PropertyChanged; 

     #endregion 

    } 
    public class Player 
    { 
     public int ID { get; set; } 
     public string FirstName { get; set; } 
     public string LastName { get; set; } 
    }

在组类设置你的主窗口的DataContext的由一个实例是这样的：

public partial class MainWindow : Window 
    { 
     public MainWindow() 
     { 
      InitializeComponent(); 
      DataContext = new Team 
      { 
       Players = new List<Player>() 
       { 
        new Player{ ID=1, FirstName="Mohammed", LastName="Ali" }, 
        new Player{ ID=2, FirstName="Paul", LastName="Oshain" }, 
       } 
      }; 
     } 
    }

并最终在您的XAML（您的MainWindow）中做出很好的约束;像这样：

<Window x:Class="WpfApplication4.MainWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     Title="MainWindow" Height="350" Width="525"> 
    <Grid> 
     <DataGrid ItemsSource="{Binding Players}" AutoGenerateColumns="False" > 
      <DataGrid.Columns> 
       <DataGridTextColumn Header="Id" Binding="{Binding ID}"/> 
       <DataGridTextColumn Header="First Name" Binding="{Binding FirstName}"/> 
       <DataGridTextColumn Header="Last Name" Binding="{Binding LastName}" /> 
      </DataGrid.Columns> 
     </DataGrid> 
    </Grid> 
</Window>
