WPF RadioButton 绑定boolean值

article 2024/10/3 15:35:59

<RadioButton
    Margin="5"
    Content="替换"
    IsChecked="{Binding CorrectionOption.ReCorrectionMode}" />
<RadioButton
    Margin="5"
    Content="平均"
    IsChecked="{Binding CorrectionOption.ReCorrectionMode, Converter={StaticResource ReCorrectionModeToBooleanConverter}}" />

切记:RadioButton 不能有GroupName属性

public class ReCorrectionModeToBooleanConverter : IValueConverter
{

    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value is bool booleanValue)
        {
            return !booleanValue; // 取反
        }
        return value;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value is bool booleanValue)
        {
            return !booleanValue; // 取反
        }
        return value;
    }
}
