I'm in the BO PropertyGrid trying to set the parentBO and it says this must be set in the instance. So I go to the instance and try to set the parentBO and it says I must set it in the class properties.



Catch-22



What next?



and btw, how can I switch the parent on the fly?

can i set ParentRelationship on the fly?

Yes, you can set the parent relationship on-the-fly as well.  You can either set the properties on the object returned by the ParentRelationship property or you can create a new BusinessParentRelationship object and set the ParentRelationship property to that value.
