WPF global font size

Question

I\'m creating a WPF app and I would like to know the best way to be able to change the font size for every element in the ui. Do I create a resource dictionary and set Style

Answer 1

FontSizeProperty is inherited from Parent Control. So you just need to change FontSize of your main window.

If you don't need dynamic behaviour this should work:

Add a style for Window to your ResourceDictionary

Apply the style to your main form (will not be applied implicit because its a derived type)

 Style = (Style)FindResource(typeof (Window));
