I\'m using jQuery UI\'s draggable and droppable libraries in a simple ASP.NET proof of concept application. This page uses the ASP.NET AJAX UpdatePanel to do partial page up
If you would like to fix the minified/compressed .js file for jQuery version 1.4.2, replace:
var d=b.getBoundingClientRect(),
with
var d = null;
try { d = b.getBoundingClientRect(); }
catch(e) { d = { top : b.offsetTop, left : b.offsetLeft } ; }
(note that there is no comma after the closing brace now)
