DevExpress delivers the best collection for Winform components. Apart from a few missing functions (and naturally a few bugs) the collection is complete, the documentation clear and detailed. It contains many examples, which show you the many ways it can be used. The support and newsgroups are helpful as well, with (mostly, but not always) fast replies from DevExpress or other users. Especially when comparing the collection with competing products, no other manufacturer comes anywhere close to this quality. Only the ASP.NET components are not complete yet. The most important GUI elements (Grid and general editors) have not been converted to the new concept yet and the old Grid component is not particularly good. But I am sure that the next version will also be excellent. Up until now DevExpress has always managed to release a small update in an approx. 4 week cycle, as well as large updates with new features 3-4 times a year. Have fun with it, Holger
