C#WPF双向复选框绑定未更新

从我的代码开始：

这也没有解决问题。

实现

INotifyPropertyChanged

，然后让您的属性引发事件以实现这一点

比如：

public class MyData : INotifyPropertyChanged
{
    private bool isChecked;
    public bool IsChecked 
    { 
        get { return isChecked; } 
        set
        {
           if (isChecked != value)
           {
              isChecked = value;
              OnPropertyChanged("IsChecked");
           }
    }
    protected void OnPropertyChanged(string name)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
        {
            handler(this, new PropertyChangedEventArgs(name));
        }
    }
}

在

MyData

类中实现

INotifyPropertyChanged

怎么样？这是每个WPF员工都应该知道的最基本的事情。我所要做的就是添加：INotifyPropertyChanged到MyData。我将不得不阅读这篇文章，因为我对WPF和C#基本上还是新手。谢谢！！！：]嗯，你需要用你所有的财产做那些无聊的事情（否则你可能会有类似的问题），但你得到了要点：-）

public partial class MainWindow : Window
{
    ObservableCollection<MyData> MyItems = new ObservableCollection<MyData>();

    public MainWindow()
    {
        datGrid.ItemsSource = MyItems;
        MyItems.Add(new MyData { IsChecked = false, Username = "apetecca", FirstName = "Anthony", LastName = "Petecca", Email = "apetecca@email.com"});
        MyItems.Add(new MyData { IsChecked = true, Username = "jhalls", FirstName = "Jake", LastName = "Halls", Email = "jhalls@email.com" });

    }

    public class MyData
    {
        public bool IsChecked { get; set; }
        public string Username { get; set; } 
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string Email { get; set; }
    }

    private void headerCheckBox_Checked(object sender, RoutedEventArgs e)
    {
        foreach (var item in MyItems)
        {
            item.IsChecked = true;
        }
    }

public class MyData
{
    private bool _isChecked;
    public bool IsChecked
    {
        get { return _isChecked; }
        set 
        { 
            _isChecked = value;
            OnPropertyChanged("IsChecked");
        }
    }
    public string Username { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Email { get; set; }

    private void OnPropertyChanged(string propertyName)
    {
        if (PropertyChanged != null)
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
    }

    public event PropertyChangedEventHandler PropertyChanged;
}

public class MyData : INotifyPropertyChanged
{
    private bool isChecked;
    public bool IsChecked 
    { 
        get { return isChecked; } 
        set
        {
           if (isChecked != value)
           {
              isChecked = value;
              OnPropertyChanged("IsChecked");
           }
    }
    protected void OnPropertyChanged(string name)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
        {
            handler(this, new PropertyChangedEventArgs(name));
        }
    }
}
