Gaia Ajax Widgets is a framework built on top of the native ASP.NET server controls which means it will interact fully with the page rendering cycle. This means that you can edit properties in any widget on your page from any event handler of any widget on that same page.
Gaia Ajax Widgets is very easy to use! Gaia was built to mimic 100% the logic of conventional ASP.NET and basically this means that if you know ASP.NET you know how to use Gaia Ajax Widgets! Gaia Ajax Web Widgets does not have ANY cryptic properties or code model you need to learn before you can use Gaia effectively, almost none of our controls uses any other properties than the ones that comes with native ASP.NET so if you know your way around ASP.NET you know your way around Gaia! This can be seen from the fact that you don't need to use WebServices to e.g. populate our AutoCompleter and from the event that retrieves the AutoComplete data you can do whatever you like, including for instance making a DropDownList visible or showing a modal window.
Lightweight: Gaia Ajax Widgets mirrors the whole ASP.NET WebControl hierarchy on a demand basis meaning that the bandwidth consumed in a Gaia application will be far less than the bandwidth consumed in most other Ajax Frameworks. If you use e.g. FireBug in FireFox you will see that the stuff sent across the wire in Gaia Ajax CallBacks is in fact not HTML but rather small bursts of commands to specific objects on the client side.
