ValueConverter绑定Silverlight 5中的Polygon Fill属性

我正在尝试使用ValueConverter将Fill属性绑定到ModelView中的bool属性IsBottomSelected

这是我的xaml for polygon:

  <Polygon Name="h_bottom" Points="50,50 0,100 100,100 50,50" Stroke="Green" StrokeThickness="3"  MouseLeftButtonDown="h_bottom_MouseDown" >
        <Polygon.Fill>
            <Binding Path="IsBottomSelected">
                <Binding.Converter>
                    <view:BoolToColorConverter/>
                </Binding.Converter>
            </Binding>
        </Polygon.Fill>
    </Polygon>

这是ValueConverter:

public class BoolToColorConverter : IValueConverter
{

    object IValueConverter.Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {

        try
        {

            if (Convert.ToBoolean(value.ToString())) return new SolidColorBrush(Colors.Cyan);

        }

        catch { }

        return new SolidColorBrush(Colors.White);

    }



    object IValueConverter.ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return null;
    }

}

相同的代码在WPF中工作,在Silverlight 5中没有触发ValueConverter。
