Testimonials

We have been using DevExpress since 2009 and we use it to build our WinForms and Web applications. The online resources: FAQs, Foruns, Webinar and Videos are fantastic and help us a lot. Another great aspect is the evolution of the product. We are always receiving great new features.

Thanks DevExpress for your great product!

Today is impossible for our developers team to imagine how it would be to develop without the DevExpress controls. We use it to build our WinForms and Web applications and our clients love the appearance and the possibility to change themes and colors of the controls. It's seems like it does not matter for the product, but sometimes is what the costumer likes the most. Besides that, on the development side, it is really easy and reliable to design and create with the DevExpress controls. It takes developing software to another level, bringing powerful and easy to use tools to the developer. Adding to that, it has a great documentation and an even better support center.

While planning for our application development we looked out for 3rd party tools which shall not only help us develop application speedily, but also not compromise on Flexibility, features and Excellence of Design. DevExpress tools merges all these features into one. Regular DevExpress Updates provide us latest and faster technology without much efforts on our part. Thanks a lot for Providing us an opportunity to use your products. DevExpress is a market leader in product quality and we trust them for our application.

We have been using DevExpress for a long time and it helps us save so much time in development and now we can not imagine our products without using DevExpress Controls. As DevExpress is present in most of our development enviroment, sometimes we need support and this is another thing that counts in DevExpress, because we have quick and effective answers to our questions whenever we need it.

Thank you! You make amazing suites, with a full range of controls, data display and analysis, ORM tools and so much more! They are very easy to use. Thanks to the DevExpress suites, I do much better in my project development with less work.

I purchased the WinForms course and in just a few hours I learned the equivalent of months of researching on my own.
Thank You!

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!
