Hello Derek,
In order to set the theme to Desert, please note that
you should drag and drop the Desert theme component on your form. I am attaching a sample project to demonstrate the correct behavior. If you continue experiencing the issue, please open a new support ticket and send me a sample application which reproduces it. This will allow us to investigate the case further and to give you more accurate response.
Regarding RadRibbonBar, currently the Desert theme component does not contain a theme for this control. It will be provided in one of our next versions. I want to assure you that we are constantly expanding our theme suite in order to provide consistency in your applications' theming.
I hope this helps. If you have additional questions, feel free to contact me.
Sincerely yours,
Nikolay
