The DevExpress .NET Products Installer installs demos for each product. Demos are divided into two types: Sample Applications (real-world applications built with a combination of DevExpress controls) and Technical Demos (which highlight the primary features of a particular product).
To see DevExpress demos in action, run the Demo Center application from the Windows Start menu (All Programs | DevExpress 19.2 | Demo Center 19.2) or via the executable file located in the directory in which DevExpress products were installed ("C:\Users\Public\Documents\DevExpress Demos 19.2\Components\Components\Bin\DevExpress.DemoCenter.v19.2.exe" by default).
In the Demo Center, click ASP.NET to view available feature-based demos.
Solution files (with C# and VB.NET source code) for technical demos are included in the installation – to demonstrate how to use DevExpress controls.
Run a solution from the corresponding directory to see the source code for a specific demo ("C:\Users\Public\Documents\DevExpress Demos 19.2\Components\...").
