Hi,

I'm afraid that EPiServer does not have any API to support this. I think possible workaround solution could be the attribute system. You can set an attribute named something like clubID for each NewsBlog whenever it was created, then retrieve the Club that the NewsBlog belongs to by that attribute later.

I think Tien is wrong, at least when it comes to recent versions of Community/Relate.

Try this:

IEntity ownerEntity = ((IOwnable)blog).OwnedBy.Entity;
if (ownerEntity is EPiServer.Community.Club.Club) { ... }
