A while back I was looking at the AJAX toolkit page (http://ajax.asp.net/ajaxtookit) and I was really not impressed with anything I saw.
Things like the “Confirm” button, which is basically a button with 10 seconds of javascript coding built into it isn’t a big deal, IMO.
But their list of controls has really grown and there are some really interesting things in that toolkit.
It still boggles my mind that they don’t have an autocomplete dropdown list where your selections are LIMITED to the choices from the list.
