WPF/XAML: How to make all text upper case in TextBlock?

Question

I want all characters in a TextBlock to be displayed in uppercase

Answer 1

I use a character casing value converter:

class CharacterCasingConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        var s = value as string;
        if (s == null)
            return value;

        CharacterCasing casing;
        if (!Enum.TryParse(parameter as string, out casing))
            casing = CharacterCasing.Upper;

        switch (casing)
        {
            case CharacterCasing.Lower:
                return s.ToLower(culture);
            case CharacterCasing.Upper:
                return s.ToUpper(culture);
            default:
                return s;
        }
    }

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