wpf RadioButton按钮绑定数据过程

1、创建数据转换

public class RadioConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            return value == null ? false : value.Equals(parameter);
        }

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

2、视图加上

  <WrapPanel  >
            <TextBlock >品牌:</TextBlock>
            <RadioButton  IsChecked="{Binding Path=FBrand,Mode=TwoWay ,Converter={StaticResource RadioConverter}, ConverterParameter=0}">test1</RadioButton>
            <RadioButton  IsChecked="{Binding Path=FBrand,Mode=TwoWay ,Converter={StaticResource RadioConverter}, ConverterParameter=1}">test2</RadioButton>
            <RadioButton  IsChecked="{Binding Path=FBrand,Mode=TwoWay ,Converter={StaticResource RadioConverter}, ConverterParameter=2}">test3</RadioButton>
            <RadioButton  IsChecked="{Binding Path=FBrand,Mode=TwoWay ,Converter={StaticResource RadioConverter}, ConverterParameter=3}">test4</RadioButton>
        </WrapPanel>

3、viewModel绑定

FBrand=“0”//FBrand="1"//FBrand="2"//FBrand="3"
