Do NOT be put off by the early reviews of this product, the current versions of the controls or at least from 2007 v1 have been significantly improved. The inclusion of the Ribbon tool, the UI styling. Flexgrid is extremely efficient, trueDBgrid with it's simple sorting and grouping facility is essential for rapid development. I have used many of the controls for one purpose or another and I have not had reason to purchase another toolset. I have found my development process improved with the ease of use the controls. I haven't as yet used the WPF toolset so cannot comment on those particular tools. Thumbs up from me.
