在WPF中将单选按钮组绑定到属性

让我们想象我有:





然后在我的数据源类中有:




public bool RadioButton1IsChecked { get; set; }
public bool RadioButton2IsChecked { get; set; }
public enum RadioButtons { RadioButton1, RadioButton2, None }
public RadioButtons SelectedRadioButton
{
    get
    {
        if (this.RadioButtonIsChecked) 
            return RadioButtons.RadioButton1;
        else if (this.RadioButtonIsChecked) 
            return RadioButtons.RadioButton2;
        else 
            return RadioButtons.None;
     }
}





我能否直接将我的单选按钮绑定到SelectedRadioButton属性？我只需要RadioButton1IsChecked和RadioButton2IsChecked属性来计算所选的单选按钮。

\n


public enum RadioButtons { RadioButton1, RadioButton2, None }
public RadioButtons SelectedRadioButton {get;set;}
 public class EnumBooleanConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            var ParameterString = parameter as string;
            if (ParameterString == null)
                return DependencyProperty.UnsetValue;
            if (Enum.IsDefined(value.GetType(), value) == false)
                return DependencyProperty.UnsetValue;
            object paramvalue = Enum.Parse(value.GetType(), ParameterString);
            return paramvalue.Equals(value);
        }
        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            var ParameterString = parameter as string;
            var valueAsBool = (bool) value;
            if (ParameterString == null || !valueAsBool)
            {
                try
                {
                    return Enum.Parse(targetType, "0");
                }
                catch (Exception)
                {
                    return DependencyProperty.UnsetValue;
                }
            }
            return Enum.Parse(targetType, ParameterString);
        }
    }

声明一个类似于以下枚举的枚举类型：




enum RadioOptions {Option1, Option2}





XAML：











转换器类：




public class EnumBooleanConverter : 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 ((bool)value) ? parameter : Binding.DoNothing;
    }
}
