Thank you, Dell. So, in general, it is possible that by modifying code in Visual Studio, from some version, you can see the group tree? Or by changing the version of Crystal SDK assemblies? I worked many years ago with Informix New Era, I was in the same office with the programmers, and from the application, we couldn't see the group tree either, only if we run .exe of the report, and they couldn't do anything, if I remember correct. I was wondering just if it's the same with Visual Studio.
