WPF: how to use 2 converters in 1 binding?

This is what I did:

public class CombiningConverter : IValueConverter
{
    public IValueConverter Converter1 { get; set; }
    public IValueConverter Converter2 { get; set; }

    public object Convert(
        object value, Type targetType, object parameter, CultureInfo culture)
    {
        object convertedValue =
            Converter1.Convert(value, targetType, parameter, culture);
        return Converter2.Convert(
            convertedValue, targetType, parameter, culture);
    }

    public object ConvertBack(
        object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

and I call it like this:

<converters:CombiningConverter
    x:Key="negatedBoolToVisibilityConverter"
    Converter1="{StaticResource NegatedBooleanConverter}"
    Converter2="{StaticResource BoolToVisibilityConverter}" />

A MultiValueConverter might also be possible I think. Maybe I’ll try that later.
