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

Implement a custom converter.

using System.Globalization;
using System.Windows.Data;
// ...
public class StringToUpperConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value != null && value is string )
        {
            return ((string)value).ToUpper();
        }

        return value;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return null;
    }
}

Then include that in your XAML as a resource:

And add it to your binding:

Converter={StaticResource StringToUpperConverter}
