wpf DataGrid行背景色绑定

1、创建BgROW类

    public class BgROW : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {

            if (value.ToString()=="true")
            {
                return new SolidColorBrush(Color.FromRgb(46, 170, 231));
            }
            else
                return new SolidColorBrush(Color.FromRgb(229, 73, 54));
        }
        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

2、在xaml中引入BgRow，然后在<ResourceDictionary>中加入<Bg:BgROW x:Key="bgRow"/>，最后添加<Setter Property="Background" Value="{Binding IsErr, Converter={StaticResource bgRow}}"/>对行背景色进行绑定

        <DataGrid x:Name="dgProduct" Grid.Row="1" Margin="50,30,50,30" Background="
