AJAX events define an interaction sequence between a client and the server.
Typically, javascript will trigger the AJAX event which executes code and updates a region on the page.
For example, ticking a box might send data to the server, and depending on it's value, show or hide additional content on the page.
Any javascript event on an Oncord control can trigger an ajax event.
Just specify the native event name, suffixed by ajax.
For instance: onclickajax="..." and onchangeajax="...".
