I have a WinApp with a Form in which I'd like to let the user edit a list of Entities in a DataGridView; meaning changing existing, adding new ones and deleting newly added or existing entities. But the user should be able to discard all "his work" or save it. Lates version of NHibernate 2 by the way.
Based on secion 10.4.1 "Long session with automatic versioning" in the manual(http://www.hibernate.org/hib_docs/nhibernate/1.2/reference/en/ html_single/#transactions-optimistic), I do the following when opening the Form: - open a session with ISessionFactory.OpenSession() and store it in a class property - load all data with Session.Load(...) - disconnect the session with Session.Disconnect() - bind the list of entities to the a BindingSource bound to my DataGridView Editing the entities in the list is no problem. But unfortunately I can't find a way to add/attach new entity to the session without getting them immediately writen to the database. I just want a new entity to add/attache to the session, so I can let NHibernate do the required INSERT und UPDATE queries when I flush/commit the changes to the database on button_OK. Session.Merge and Session.Save throw an error saying that the session is not connected. And if I do so (what I actually don't want at this stage) then the new records are directly written to the database. Setting Session.FlushMode to FlushMode.Commit did not work. Any ideas how to do that? Thank in advance Daniel --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "nhusers" group.
