In order to customize the font size and style of our controls, I'd recommend using an implicit styles approach
. Specifically, you can use the ResourceDictionaries
we provide with our assemblies and create custom styles based on the default styles as described in the Basing Styles
section of this tutorial.
Also in case you're using Windows8
themes you can take a look at this article
describing how to change the fonts of the Telerik controls.
Let me know if this information helps and if I can further assist you.
