Do you know any? I'm just porting my brain to asp.net and one thing I was wondering is that each control, from differente resellers, in particular ajax controls, each has his sets of js code... if you put 3-4 ajax controls from different vendors in a single page, you will end up having tons of js code doing the same things... right? I was wondering if there are ajax controls around, from different vendors, using common libraries like mootools or the like.
I don't know about different ajax controls from different vendors all sharing the same common code, I've never seen anything like that. But if you code them yourself than you can just have them all use the same shared library.
