Check out this 7 minute video on how to use CodeCentral. To learn a new product or tool, I find one of the best ways is to play with sample source code. CodeCentral is your portal to search, download and run tons of sample source code. To get started, just install a small tool direct from the website and then run our samples in your local Visual Studio.
CodeCentral’s main purpose is to be a learning tool. A good tutorial is almost like a cheat code for a game. It can help raise you to a new level in a short time. CodeCentral is kind of like cheat codes but without the guilt. 
What’s in DevExpress CodeCentral?
Sample projects with source code of our ASP.NET Tutorials and also the many support issues which contain samples for our other products (including WinForms).
Does it cover all DevExpress components?
Yes, however there are more ASP.NET samples at the moment.
Is it only DevExpress components?
Yes. Though some samples show you how to integrate with other technologies like Microsoft Ajax.
Is it available to anyone or just DevExpress customers?
It’s available to everyone. No need to sign in.
Is it free?
Yes!
Does it work with the trial?
Yes. Our trial is fully functional.
Do you need to have Visual Studio Professional, Enterprise, or Team System to see the code?
Not necessarily. You can also use the free Visual Studio Express Editions.
What about Delphi?
Sorry, we're aiming to get .NET fully supported before we look at VCL.
What about browsing the code?
Yes, you can browse many of the samples online. Though, it’s to browse on a local system where you can execute and step into source code.
Are these DevExpress written samples, user samples or both?
Both but for the most part, they’re written by the support and R&D teams.
