Hello Diane,
The Auto Save Content example describes how the editor content can be sent to the server on a specific time interval by using an asp:Timer control. It does not explain how to save it in the database. You can see how the content is saved in external sources in the following examples.
Editor - Save in Database
Editor - Save in External File
On your second question: 2. You mentioned that I made need an 'upgrade to ASP.NET AJAX, WPF or WinForms projects'. I am using the most current version of the radeditor. Thus why would I need to upgrade these other items? - In my previous post I do not suggest upgrades of any kind. The functionality you described does not depend on the version of Telerik UI for ASP.NET AJAX because it is not present in the RadEditor control. The developer can get or set the content in the editor by using its Content property. The answers of the questions "How is the data saved to the database?" and "What 'connections' or wiring needs to be setup?" depend on the application infrastructure and are not related the the editor itself. Actually Telerik provides professional services and training for your most difficult projects. More information about this can be found here http://www.telerik.com/professional-services.
