This is a great tool for developers who want quick and efficient results without the hassles of low level coding. It has been my companion for years and I don't think I will drop it anytime soon.

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.

ComponentOne products are among the few components I can actually rely on in a production environment. I can trust them like I trust my own code. I use a number of ComponentOne components (ActiveX, WinForms and WebForms) and all are very stable & mature. The few bugs I've encountered over the years have been fixed promptly. While other companies are happy to sit on their existing code and react to market changes as they occur, ComponentOne has consistently remained ahead of the curve by improving their products and offering new ones early enough for developers to release them "on time". They are an early-adopter's dream and I wish every company was as forward-thinking. On a scale of 1 to 5, I give ComponentOne a 5.

I found the ComponentOne TrueData controls too buggy and unreliable. My code was filling up with 'fixes' to work around problems so their controls would work properly. After converting a DAO project to ADO, I found the ADO versions of the controls crashing all over the place. Maybe it was my computer, but I suspect not. No other controls that I use cause ADO crashes. Anyway, that was as much as I was prepared to put up with, so I dumped TrueData and I'm now using Janus GridEx for grids, plus went back to intrinsic dropdown controls. I haven't had any more ADO problems. My code is signficantly smaller, I've been able to add more features due to better interaction with the control (including sub-classing) and I've found GridEx to be extremely reliable, despite it not having had any updates for a while. TrueData would be good if it was reliable, but despite lots of fixes, I've not seen any improvements. Please note that ComponentOne VSFlexGrid does NOT suffer from these problems and is a good, reliable control. If you want a nice, easy to use grid, although not with all the binding methods of TrueData, then try Janus GridEx. I haven't found a good multi-column combo to replace TrueDBCombo (which I liked, except for it's reliability), so I built one using GridEx.
