  <p>I'm looking for general guidance on how to implement an "auto-save" feature in ASP.NET 4.0. I have an application with a tabbed interface (AJAX Control Toolkit) and a user can make changes in a variety of fields and tabs at any given time. I need to create an auto-save for (1) every time changes are made to fields and (2) save everything every 3 seconds (or what not).</p>
  
  <p>I've never implemented something like this and I'm looking for guidance one it. Obviously, I'm assuming that there's some AJAX involved, I just don't know how to go about it.</p>
