Thank you for the question.
sets the ThemeName of all controls to one and the same value. It does not set ThemeName per control type basis.
When you create custom themes for different controls, you should load these themes in your applications by following the instruction provided in this article
. When you later set the ThemeResolutionService.ApplicationThemeName to the custom ThemeName value, all controls that have custom themes will be styled accordingly. If there are other controls which do not have custom themes defined, they will be styled in the ControlDefault theme.
I hope that this information is helpful. In case there are any specific questions about our theming mechanism, feel free to contact us back.
All the best,
