GridView is a great control, and out of the box it does a lot of wonderful stuff, but I haven't worked on a project yet where it did everything I needed.  "Real World GridView" is an attempt to share some of the common customizations I end up doing to GridView on a regular basis.

I finally got around to posting the second article in the series.  This article deals with tweaking GridView's inner table to add custom rows and secondly with grouping data in a GridView.
