The idea is to start with a set of predefined user controls so that you don't have to recreate the whole functionality from scratch. The user controls can be found in the folder of your local installation of Telerik.Web.UI suite -> Live Demos\Scheduler\Examples\AdvancedFormTemplate.
If you use these user controls, the advanced template will look exactly like the default advanced form, but you will be able to edit the user controls as per your need.
All the best,
the Telerik team
