The Server Control API section explains the methods and properties available in code behind for Ektron's CMS400.NET Server Controls. 

Ektron CMS400.NET’s server controls let you insert many standard methods and properties within a Visual Studio environment. This means that you can see the effect of your changes in real time -- you don’t have to modify a page then compile a sample project to see the results.
