I want all texts in TextBlock, Label, MenuItem.Header to be displayed in upper case.
The strings are taken from a ResourceDictionary e.g.:
<TextBlock Text="{StaticResource String1}"/>
<MenuItem Header="{StaticResource MenuItemDoThisAndThat}"/>
etc. (also for Label and other controls)
I cannot use a value converter because there is no binding. I don’t want to make the strings upper case in the dictionary itself.
You still can use a converter, just set the textvalue in the source of the binding :
