My team develops most of the business logic into a dll and calls necassary objects directly from an aspx file. We found that if we implemented code behind, then we would be moving html into "Servlet, perl script"-like methods. Didn't we progress away from that with introducing ASP, and JSP in the first place. I wouldnt want a ton of write("") calls in my classes. To us it seems like Code-behind is a step backwards in technology. If you have an html error somewhere on your page, now instead of quickly going through your document you have to eyeball through tons and tons of server side controls and god for bid you want to make a style change that wasnt implemented. I would really like to see how everyone overcomes this.
