Testimonials

We have used DevExpress tools for almost 8 years. I have seen the improvement and hard work the DevExpress team has put into meeting expectations. I really appreciate it, and all the support provided by the DevExpress support team in recent years with a quick turnaround.

I recently started using the Dev Express XtraGrid and was having problems using a hierarchical grid. I submitted a support ticket and I got a very prompt reply from the DevExpress Support team requesting additional information in the form of the application I was struggling with. We exchanged comments back and forth several times until my problem was resolved in the way that I wanted to do it. I was also pointed towards some very helpful articles which showed different ways of achieving the same thing and given advice on the pros and cons of each method. I wanted to display potentially very large amounts of data in the Dev Express XtraGrid and I was pointed toward the Server Mode as an efficient method. At all times the support team was polite and courteous and above all, in my case, extremely patient.

I am definitely using the WPF tools, and specifically the Data Grid. It is awesome. We are targeting Windows 7 desktop client development, so we will use WPF, rather than WinForms or any of the Web stuff. I have already adapted your "Live Data" demo in GridDemo.sln to get the data by calling a servlet on our Java mid-tier and using Google's protobuf to shoot the Java objects across and interpret them as .NET objects in the client. It works great!

In 2005 an astronomy program of mine started to become more research/hobby and I needed to handle large volumes of data in a grid. I looked at two other offerings unsuccessfully, so I tried Developer Express. The ExpressQuantumGrid has taken everything thrown at it. Excellent performance, easy to get going, good look and feel - its group, filter and sort function is great. This lets me get on with programming the internals - which are mathematically "interesting" and at times challenging. Next month the data volumes will increase to 800000 rows. No problem. Developer Express provides a first rate support service and their knowledgebase has already answered most of my questions. The few questions that I have asked have been promptly and courteously answered. The user interface has really impressed everyone who has seen it!

I just wanted to thank you and all of your team for making my life easier and for producing a most remarkable suite of software that in my opinion is un-paralleled anywhere. I have been using your VCL components since 2001 and my application has grown with your new releases. I recently have moved over to ASP.NET and the first thing I insisted on was a full DevExpress subscription and yet again I was not disappointed. I feel without any exaggeration that DevExpress is the pinnacle of software development companies.

You are the best!. I tried ASP NET controls from some of your competitors, But you are incredible. We will buy very soon learning's videos for ASP solutions!

Managers like reports, programmers control and end users, usability. From a programmer's point of view, the vast majority of time is spent coding business rules and data-interaction, but without a good vision of how the information should be presented, or how the user will interact with your application, designing a whole solution can easily bottle-neck at the UI. DevExpress has bridged a major gap in this realm. The controls are well designed, fast performing and bring a modern edge to even the simplest of mockups. Furthermore, if you cannot discern a solution from the documentation or forums, their support staff is consistent in getting back to you within a working a day. I've been using DevExpress controls for over 5 years now, and their products are the foundation for much of what I do, even when the data is not bound to a data-source.

I am a long-time DevExpress user (used VCL suite for Delphi back in 1999) and have been an ardent fan of the products and more importantly, the excellent support they have always provided consistently. Migrating from VCL to C# ASP.NET, I still get amazed (as a little kid) on discovering the potential of the products. Amazing suite, with support parallel-to-none!

Thanks to DevExpress I have been able to significantly improve my clients applications. Since turning to DevExpress from a competitor I have been easily able to upgrade my clients systems, and provide features that were previously virtually impossible. With the 90-odd controls available in ASP.net as well as theming I am now able to create the kind of systems that are beautiful as well as functional.

Thanks DevExpress for your great product and the excellent support you have given me thus far!

Amanda, thanks for being such a great host on those videos which I enjoy watching very much. They give me a great impression on how to do things and how easy they actually are using the right tools. I have used other libraries but am hooked to DevExpress, you guys are really great! Keep up the good work and God bless from Germany.
