If the members are in different classes/structs and are marked as private. You will need to use the default level of internal if the classes/structs are within the same assembly.
If they are in different assemblies, then the members will need to be marked as public to be accessible.

In your code, just check the method DisplayGroupTree which you're trying to access is not private.

Please also note that you can span a single class/struct across multiple source files using the partial keyword.
