我有三个单选按钮和三个组框，根据单选按钮的选择，组框应该是可见或折叠的，但这里似乎没有任何效果。我的构造函数的代码被执行，但似乎事情仍然相互重叠。

这是转换器的代码

    namespace Finance.MainUI.Common.Converters
    {
    public class BoolToVisibilityConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            return (bool) value ? Visibility.Visible : Visibility.Collapsed;
        }

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

Visibility将绑定更改为：

<GroupBox Grid.Row="7" Grid.Column="1" 
    Visibility="{Binding 
        RelativeSource={RelativeSource FindAncestor, 
            AncestorType={x:Type UserControl}}
        Path=DataContext.IsMonthlyInterestChecked, 
        UpdateSourceTrigger=PropertyChanged, 
        Converter={StaticResource  VisibilityConverter}}" >

然后将属性添加IsMonthlyInterestChecked到您的ViewModel并绑定RadioButton到它：

<RadioButton Grid.Column="0" x:Name="rdbMonthlyInterest"  
    Content="Monthly Interest" 
    Style="{StaticResource RadioButtonWhite}" 
    IsChecked="{Binding IsMonthlyInterestChecked}"/>
