简单的ListView数据绑定

我正在尝试显示数据ListView使用 WPF 和 C#，我对所看到的不同示例和方法感到困惑。我正在寻找一个与我的程序类似的完整工作示例，或者使其工作的先决条件列表。如果我能够仅显示我的集合中的 1 行数据，我会很高兴。目前，列表视图不显示任何内容。

C#:

public partial class MainWindow : Window
{
    public ObservableCollection<Row> Rows { get; set; }

    public MainWindow()
    {
        InitializeComponent();
        Rows = new ObservableCollection<Row>();
        Rows.Add(new Row 
        {
            ID = "42",
            Category = "cat",
            CharLimit = 32,
            Text = "Bonjour"
        });
    }
}

public class Row
{
    public string ID { get; set; }
    public string Category { get; set; }
    public int CharLimit { get; set; }
    public string Text { get; set; }
}

XAML:

<ListView ItemsSource="{Binding Path=Rows}">
    <ListView.View>
        <GridView>
            <GridViewColumn Width="200" Header="ID" DisplayMemberBinding="{Binding Path=ID}" />
            <GridViewColumn Width="200" Header="Category" DisplayMemberBinding="{Binding Path=Category}" />
            <GridViewColumn Width="200" Header="Text" DisplayMemberBinding="{Binding Path=Text}" />
        </GridView>
    </ListView.View>
</ListView>

创建一个viewmodel可以将其设置为 XAML 的数据上下文

 public class WindowsViewModel
 {
    private ObservableCollection<RowViewModel> m_Rows;

    public ObservableCollection<RowViewModel> Rows
    {
        get { return m_Rows; }
        set { m_Rows = value; }
    }

    public WindowsViewModel()
    {
        Rows = new ObservableCollection<RowViewModel>();
        Rows.Add(new RowViewModel
            {
                ID = "42",
                Category = "cat",
                CharLimit = 32,
                Text = "Bonjour"
            });
    }
}

实施班级RowViewModel按以下方式：

 public class RowViewModel:INotifyPropertyChanged
    {
      public RowViewModel()
      {
      }
      private string m_ID;
      public string ID
      { 
            get
            {
                return m_ID;
            } 
            set 
            {
                m_ID = value;
                NotifyPropertyChanged("ID");
            }
      }
      public string Category
      { 
            get; 
            set; 
      }

      public int CharLimit
      { 
        get; 
        set; 
      }

      public string Text 
      { 
        get;
        set;
      }

    public event PropertyChangedEventHandler PropertyChanged;

    private void NotifyPropertyChanged(string Obj)
    {
        if (PropertyChanged != null)
        {
            this.PropertyChanged(this,new PropertyChangedEventArgs(Obj));
        }
    }
}

在XAML后面的代码中添加以下代码：

public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            this.DataContext = new WindowsViewModel();
        }
    }

在listview节点中添加更新源触发属性：

<ListView ItemsSource="{Binding Rows, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}">
            <ListView.View>
                <GridView>
                    <GridViewColumn Width="200" Header="ID" DisplayMemberBinding="{Binding Path=ID}" />
                    <GridViewColumn Width="200" Header="Category" DisplayMemberBinding="{Binding Path=Category}" />
                    <GridViewColumn Width="200" Header="Text" DisplayMemberBinding="{Binding Path=Text}" />
                </GridView>
            </ListView.View>
