It should be available in the sample folder installed along the components by the installation package.
Under XP, it should be here (if you have not chosen another folder at installation) :
C:\Program Files\Xceed Components\Xceed Grid for .NET <version>\Samples\CSharp\Extensibility
Under Vista, it should be here (again if you have not chosen another folder at installation):
C:\Xceed Component Samples\Xceed Grid for .NET <version>\Samples\CSharp\Extensibility
