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

Question

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

<TextBlock Name="tbAbc"
           FontSize="12"
           TextAlignment="Center"
           Text="Channel Name"
           Foreground="{DynamicResource {x:Static r:RibbonSkinResources.RibbonGroupLabelFontColorBrushKey}}" />

The strings are taken through Binding. I don't want to make the strings uppercase in the dictionary itself.

Answer 1

Or use

Typography.Capitals="AllSmallCaps"

in your TextBlock definition.

See here: MSDN - Typography.Capitals

EDIT:

This does not work in Windows Phone 8.1, only in Windows 8.1 ...

Answer 2

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:

<local:StringToUpperConverter  x:Key="StringToUpperConverter"/>

And add it to your binding:

Converter={StaticResource StringToUpperConverter}
