How to make all text upper case / capital?

Question

I want all texts in TextBlock, Label, MenuItem.Header to be displayed in upper case. The strings are taken from a ResourceDictio

This does not strictly answer the question but does provide a trick to cause the same effect.

I believe many finding their way here are looking how to do this with a style. TextBlock is a bit tricky here because it is not a Control but a FrameworkElement and therefore you can not define a Template to do the trick.

The need to use all uppercase text is most likely for headings or something like that where use of Label is justified. My solution was:

<!-- Examples of CaseConverter can be found in other answers -->

<ControlTemplate x:Key="UppercaseLabelTemplate" TargetType="{x:Type Label}">
    <TextBlock Text="{TemplateBinding Content, Converter={StaticResource CaseConverter}}" />
</ControlTemplate>

<Style x:Key="UppercaseHeadingStyle"
       TargetType="{x:Type Label}">
    <Setter Property="FontSize" Value="20" />
    <Setter Property="FontWeight" Value="Bold" />
    <Setter Property="Template" Value="{StaticResource UppercaseLabelTemplate}" />
</Style>

<!-- Usage: -->
<Label Content="Header" Style="{StaticResource UppercaseHeadingStyle}" />

Note that this does disable some of the default behavior of Label, and works only for text, so I would not define this as default (no one probably wants all labels uppercase anyway). And of course you must use Label instead of TextBlock when you need this style. Also I would not use this inside of other templates, but only strictly as a topic style.
