如何选中所有复选框C#

我有几个复选框，我希望Functionality选中或取消选中all复选框。下面是class.cs和xaml代码。如何为“全部选中”或“全部取消选中”添加功能性

    public static event PropertyChangedEventHandler IsCheckedChanged;
    private bool isChecked;

    public WorkStep(string name)
    {
        Name = name;
        IsChecked = true;
    }

    public WorkStep(string name, bool isChecked)
    {
        Name = name;
        IsChecked = isChecked;
    }

    public string Name
    {
        get;
    }

    public bool IsChecked
    {
        get { return isChecked; }
        set
        {
            isChecked = value;
            OnIsCheckedChanged();
        }
    }

    private void OnIsCheckedChanged()
    {
        PropertyChangedEventHandler handler = IsCheckedChanged;
        if (handler != null)
            handler(this, new PropertyChangedEventArgs("IsChecked"));
    }

和xaml：

                                <DataGridTemplateColumn.CellTemplate>
                                    <DataTemplate>
                                        <CheckBox IsChecked="{Binding IsChecked, UpdateSourceTrigger=PropertyChanged}" HorizontalAlignment="Center"/>
                                    </DataTemplate>
                                </DataGridTemplateColumn.CellTemplate>

我将使用

INotifyPropertyChanged

界面，如下面的类所示：

public class myClass : INotifyPropertyChanged
{
    private bool _IsChecked;
    public bool IsChecked
    {
        get { return _IsChecked; }
        set
        {
            _IsChecked = value;
            OnPropertyChanged("IsChecked");
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    protected void OnPropertyChanged(string name)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name));
    }
}

然后我将属性

IsChecked

绑定到我的所有复选框，如xaml中所示：

<Grid>
    <CheckBox x:Name="checkBox1" IsChecked="{Binding IsChecked,UpdateSourceTrigger=PropertyChanged}" Content="CheckBox" HorizontalAlignment="Left" Margin="116,90,0,0" VerticalAlignment="Top"/>
    <CheckBox x:Name="checkBox2" IsChecked="{Binding IsChecked,UpdateSourceTrigger=PropertyChanged}" Content="CheckBox" HorizontalAlignment="Left" Margin="116,126,0,0" VerticalAlignment="Top"/>
    <CheckBox x:Name="checkBox3" IsChecked="{Binding IsChecked,UpdateSourceTrigger=PropertyChanged}" Content="CheckBox" HorizontalAlignment="Left" Margin="116,164,0,0" VerticalAlignment="Top"/>
    <Button x:Name="button" Content="Button" HorizontalAlignment="Left" Margin="380,235,0,0" VerticalAlignment="Top" Width="75" Click="button_Click"/>
</Grid>

我通常会列一个清单：列出我的箱子，并将箱子添加到清单中。然后我可以简单地编写代码来枚举列表。

public MainWindow()
{
    InitializeComponent();
    DataContext = MyClass;
}

myClass MyClass = new myClass();

private void button_Click(object sender, RoutedEventArgs e)
{
    if(MyClass.IsChecked)
        MyClass.IsChecked = false;
    else
        MyClass.IsChecked = true;
}
