I need TextBlock.Text to be retrieved from translation manager, something like

<TextBlock Text="{Binding TranslateManager.Translate('word')}" />

I don't want to set DataSource for all text blocks. The only way I found how to do this is to bind to "static" class and use converter:

<TextBlock Text="{Binding Value, 
                  Source={StaticResource Translation}, 
                  Converter={StaticResource Translation}, 
                  ConverterParameter=NewProject}" />

And these helper class

 public class TranslationManager : IValueConverter
 {
  public static string Translate(string word)
  {
     return translate(word);
  }

  // this is dummy for fake static binding
  public string Value { get; set; }

  public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
  {
     var name = parameter as string;
     return TranslationManager.Translate(name, name);
  }
 }

But, is there a better - shorter - way?
