Great suite of controls - used for several years now, But the help and support so severely lacking its almost useless. I use CSLA.NET so binding to ILists is important for me and most of the examples bind to a dataset (who uses datasets in serious application development anyway). Hours and hours of searching through KB articles and forums are sometimes required to find information and then you give up and spend hours and hours using test harnesses. You cannot seem to be able to control databinding in anyway. Why can't dev express have an attribute that can be applied to prevent binding on a given property (they may already have it but the help and support is so poor I've never been able to find it). The help and examples stop short at anything more than a simple desktop application - anything involving N-Tiers and your on your own, Must be a serious market for a decent book to be written on this suite. In summation any product is only as good as its help and support so I can only give three stars - a shame for an otherwise excellent product.
