As you might recall from posts last November I gave a short BOF talk on AJAX in Delphi at the last Borland Conference. As I'm looking further to make a few more experiments with this technology (along with Internet Express), I've found the time to publish that example on a brand new AJAX demo site from mine, http://ajax.marcocantu.com/.
The site offers a small collection of links, the code download (it is not easy to put all of the pieces together, though) and features a simple master/detail application with data fetched on request and browser-based XSLT processing to display it. Enjoy and let me know what you think. More will come. (BTW, notice that there are currently a couple of visualization errors in Internet Explorer, nothing big, though).
