【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
