Hi Rob Gaudet,
Thank you for using our services.
You have noticed correctly that the Blog Calendar control is using the RadCalendar. So styling the this control is pretty much the same as styling the RadCalendar. You have several options, here - to define inline styles for the calendar, to add styling rules for the appropriate Calendar CSS classes in your theme, or to redefine the skin of the RadCalendar. The last two options will affect globally all calendar controls on your site. For more information on how to achieve them, please take a look at:
Controling RadCalendar Appearance
Controling appearance of RadControls for ASP.NET AJAX in Sitefinity
The first approach will define appearance only for the Blog Calendar. For this you will need to download the external templates for your version of Sitefinity (if you have not already done so). Then you will need to edit the ~/Sitefinity/ControlTemplates/Blogs/BlogCalendar.ascx
and add styles there. Then you will need to map the external template to your Controls Config file with the following:
<!--Provides user interface for the blog calendar control, which displays the archive of posts in a calendar view.-->
If you need more information on working with external templates for Sitefinity controls, please take a look at the following article: How to map a view to an external template, in Sitefinity 3.6 or later?
This should do the trick.
