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.
public class StaticResourceToUpperExtension : StaticResourceExtension
{
public override object ProvideValue(IServiceProvider serviceProvider)
{
var resource = base.ProvideValue(serviceProvider);
if (resource is string str)
return str.ToUpper();
return resource;
}
public StaticResourceToUpperExtension() : base() { }
public StaticResourceToUpperExtension(object resourceKey) : base(resourceKey) { }
}
<Grid>
<FrameworkElement.Resources>
<sys:String x:Key="String1">any text</sys:String>
</FrameworkElement.Resources>
<TextBlock Text="{local:StaticResourceToUpper String1}"/>
</Grid>
