If you're using 3.5 SP1, you can use the StringFormat property on the binding:

Otherwise, use a converter:

With StringFormatConverter being an IValueConverter:

[ValueConversion(typeof(object), typeof(string))]
public class StringFormatConverter : IValueConverter
{
    public string StringFormat { get; set; }

    public object Convert(object value, Type targetType,
                          object parameter, CultureInfo culture) {
         if (string.IsNullOrEmpty(StringFormat)) return "";
         return string.Format(StringFormat, value);
    }


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

That'll do the trick.
