What I can suggest in order to style the Events calendar view is to select and apply one of the available skins which you can on review the following link
from the RadScheduler documentation. In order to set the desired skin, please edit the events widget which renders the calendar and edit the calendar template and change the Skin property of the RadScheduler control to the desired skin .
The other option is to inspect the markup and the applied styles and css classes using Firebug (For Firefox) or DevTools (Chrome) or Developer Tools (IE) and then apply your custom css styles using the !important
clause in order to override the built-in css styles and make sure that your own style will be applied.
You can use the CSS widget
in order to add the custom css styles to the page where you display the events calendar.
I hope that you will find the suggestions useful.
