Excellent, however...

Firstly, this is great work a lot of hardwork involved here.

Secondly, in my experience any DTHML widgets etc tend to be too CPU intensive especially in IE. I notice if i sort say 1000 items, you'll notice the whole machine (XP admittedly) hang for a while. Is it just me experiencing this? Even scrolling up and down is too intensive.

Cheers

Yes, you are right – DHTML applications today are still very limited, mostly because of the script and rendering performance. Your example is probably on the edge or beyond this performance limit. However as average CPU power still doubles each year – you can do many nice things today and will be able to do more tomorrow. Pushing application state through client-server round-trips is a huge pain for the developers and annoying for the end-users, and this is where ‘rich’ DHTML client can help. I am not saying you can move everything into the browser – but in many cases by moving some functionality into the front-end you can achieve better user experience and better separation between GUI and business logic, especially if you like the idea of web services etc. So you still need to use your experience and sense of reality to decide if this technology is good enough for your particular task (don’t take literally my front page ads :-).
