【WPF】值是枚举的RadioButton 绑定问题

源

1、RadioButton

2、IValueConverter

3、枚举

xaml实现

<RadioButton Content="单打热身" GroupName="wramupType" IsChecked="{Binding TrainType, Converter={StaticResource RadioButtonConverter},ConverterParameter=0}"/>
<RadioButton Content="双打热身" GroupName="wramupType" IsChecked="{Binding TrainType, Converter={StaticResource RadioButtonConverter},ConverterParameter=1}" />

Converter实现

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
    MatchTrainType s = (MatchTrainType)value;
    return s == (MatchTrainType)int.Parse(parameter.ToString());
}

public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
    bool isChecked = (bool)value;
    if (!isChecked)
    {
        return null;
    }
    return (MatchTrainType)int.Parse(parameter.ToString());
}

注意：Converter带参数和枚举的顺序
