【问题描述】：

嗨，我有一个 wpf 数据网格，它有两列说

key    Value
1       abc
2       xyz
3       pqr

我有一个复选框，其值相当于列中的键。如果选中相关键，则必须选择对应的行。选中多个复选框，选择数据网格中的多行。

【参考方案1】：

Xaml：

<StackPanel>
    <DataGrid AutoGenerateColumns="False" ItemsSource="Binding List">
        <DataGrid.Columns>
            <DataGridCheckBoxColumn Header="Check" 
                Binding="Binding IsCheck, UpdateSourceTrigger=PropertyChanged"/>
            <DataGridTextColumn Header="Key" Binding="Binding Key"/>
            <DataGridTextColumn Header="Value" Binding="Binding Value"/>
        </DataGrid.Columns>
    </DataGrid>
    <CheckBox Content="1" DataContext="Binding List[0]" IsChecked="Binding IsCheck"/>
    <CheckBox Content="2" DataContext="Binding List[1]" IsChecked="Binding IsCheck"/>
    <CheckBox Content="3" DataContext="Binding List[2]" IsChecked="Binding IsCheck"/>
</StackPanel>

后面的代码：

public partial class MainWindow : Window

    public MainWindow()
    
        //fill 'List' here...
        DataContext = this;
        InitializeComponent();
    
    //List Observable Collection
    private ObservableCollection<Row> _list = new ObservableCollection<Row>();
    public ObservableCollection<Row> List  get  return _list;  

行类：

public class Row: DependencyObject

    //Key Dependency Property
    public int Key
    
        get  return (int)GetValue(KeyProperty); 
        set  SetValue(KeyProperty, value); 
    
    public static readonly DependencyProperty KeyProperty =
        DependencyProperty.Register("Key", typeof(int), typeof(Row), new UIPropertyMetadata(0));
    //Value Dependency Property
    public string Value
    
        get  return (string)GetValue(ValueProperty); 
        set  SetValue(ValueProperty, value); 
    
    public static readonly DependencyProperty ValueProperty =
        DependencyProperty.Register("Value", typeof(string), typeof(Row), new UIPropertyMetadata(""));
    //IsCheck Dependency Property
    public bool IsCheck
    
        get  return (bool)GetValue(IsCheckProperty); 
        set  SetValue(IsCheckProperty, value); 
    
    public static readonly DependencyProperty IsCheckProperty =
        DependencyProperty.Register("IsCheck", typeof(bool), typeof(Row), new UIPropertyMetadata(false));
