I have had to do some work on Data List Views recently after migrating from 2007 to 2010 since DataFormWebParts don't really work as they should in 2010, especially when it comes to the DispForm.aspx, for example, especially because (at least I found this) it would not open the DispForm.aspx page in Modal Dialog mode. Plus the New and Edit forms would not open in Modal Dialog either. So I have found a few excellent videos by Laura Rogers that helped me a lot. Basically XSLT Views Rock!

Laura provides a lot of information so please replay the videos as you will pick up more and more as you put her advise to practice.

Hope this helps someone out there! I know it helped me a great deal.
