WPF : 6. RadioButton의 IsChecked프로퍼티와 Enum타입 바인딩하는 법

• Enum 타입

public enum FilterType { None, Size, Perent }

• Converter 정의

class EnumToBooleanConverter : IValueConverter
{
    public object Convert(object value, Type targetType, 
                          object parameter, CultureInfo culture)
    {
        return value.Equals(parameter);
    }

    public object ConvertBack(object value, Type targetType, 
                              object parameter, CultureInfo culture)
    {
        return value.Equals(true) ? parameter : Binding.DoNothing;
    }
}

• xaml 바인딩

<RadioButton IsChecked="{Binding FilterOption,    
                         ConverterParameter={x:Static service:FilterType.NONE}, 
                         Converter={StaticResource EnumToBoolean}}" .../>

<RadioButton IsChecked="{Binding FilterOption,    
                         ConverterParameter={x:Static service:FilterType.Size}, 
                         Converter={StaticResource EnumToBoolean}}" .../>

<RadioButton IsChecked="{Binding FilterOption,    
                         ConverterParameter={x:Static service:FilterType.Perent }, 
                         Converter={StaticResource EnumToBoolean}}" .../>
