WPF 布尔列复选框

Question

我想将 Datagrid 中“EstBonClient”单元格的布尔复选框更改为特定颜色。如果选中复选框，则单元格的背景颜色将为绿色，如果未选中复选框，则单元格的背景颜色将为红色。我希望复选框不在 Datagrid 中。

谢谢你们！

Xaml：

<Window x:Class="WpfApplication1.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"
    xmlns:local="clr-namespace:WpfApplication1"
    >
<Window.DataContext>
    <local:MyViewModel/>
</Window.DataContext>
<Window.Resources>
    <local:BooleanToTextConverter x:Key="booleanToTextConverter" />
    <local:BoolToColorConverter x:Key="booleanToColorConverter" />
</Window.Resources>
<Grid>
    <StackPanel Background="{Binding Path=IsChecked, Converter={StaticResource booleanToColorConverter}}">     
        <CheckBox IsChecked="{Binding Path=IsChecked}" Grid.Column="0">Check Me!</CheckBox>
        <TextBlock FontSize="30" HorizontalAlignment="Center" Text="{Binding IsChecked, Converter={StaticResource booleanToTextConverter}}" />
    </StackPanel>
</Grid>

C#： 视图模型：

public class MyViewModel : INotifyPropertyChanged 
{
    bool _isChecked;

    public bool IsChecked
    {
        get { return _isChecked; }
        set {
            _isChecked = value;
            OnPropertyChanged("IsChecked");
        }
    }

    protected void OnPropertyChanged(string name)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
        {
            handler(this, new PropertyChangedEventArgs(name));
        }
    }
    public event PropertyChangedEventHandler PropertyChanged;
}

转换器：

public class BooleanToTextConverter:IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return (bool)value ? "Est Bon Client" : "Est Mauvais Client";
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}
public class BoolToColorConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return (bool)value ? new SolidColorBrush(Colors.GreenYellow) : new SolidColorBrush(Colors.DarkRed);
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}
