Доброго времени суток. Сейчас пытаюсь перенести приложение с wpf на silverlight. Столкнулся с проблемой binding и Convertor. Есть такой код:
| Код |
<UserControl

</Style>
</mygrid:DataGrid.RowStyle>
</mygrid:DataGrid>
</Grid>
</my:TabItem>
</my:TabControl>
</Grid>
</UserControl>

и соответственно код:
| Код |
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Data;
using System.Globalization;
using System.Windows.Media;
using Extension;
namespace SecurigeClientWeb.Converters
{
public class LevelToColorConverterBack : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
try
{
Color col = new Color()
{
R = 255,
B = 0,
G = 69,
A = 0
};
List<int> d = new List<int>();
return (int)value == 4 ?
new SolidColorBrush(col)
: new SolidColorBrush(Colors.White);
}
catch (Exception ex)
{
ErrorLoger.Call(ex);
return new SolidColorBrush(Colors.White);
}
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
try
{
throw new Exception("The method or operation is not implemented.");
}
catch (Exception ex)
{
ErrorLoger.Call(ex);
return value;
}
}
}
}

Студия начинает ругаться на строки:
<Setter Property="Background" Value="{Binding Level, Converter={StaticResource LevelToColorConverterBack}}"/>
<Setter Property="Foreground" Value="{Binding Level, Converter={StaticResource LevelToColorConverterFore}}"/>
[BindingOperations_TargetMustBeFEOrCVS]
Аргументы:
Недоступны строки ресурсов отладки. Ключ и аргументы часто предоставляют достаточно информации для диагностики проблемы. См. http://go.microsoft.com/fwlink/?linkid=106663&Version=3.0.40818.0&File=System.Windows.dll&Key=BindingOperations_TargetMustBeFEOrCVS
