Hello, I spent about two hours looking into this, and I couldn't find a decent solution. I did come across these three posts: http://forums.lhotka.net/forums/p/6210/43595.aspx http://forums.lhotka.net/forums/t/5131.aspx http://forums.lhotka.net/forums/p/2672/13793.aspx There seems to be a lot of work you need to do to enable this. And it seems like it should be simple and handled by CSLA. I took a look and I think the best spot to handle setting this would be in the Lists AddNewCore. protected override object AddNewCore() { Admission item = CSLATest.Business.Admission.NewAdmission(); bool cancel = false; OnAddNewCore(ref item, ref cancel); if (!cancel) { // Check to see if someone set the item to null in the OnAddNewCore. if(item == null) item = CSLATest.Business.Admission.NewAdmission(); // Pass the parent value down to the child. Patient patient = this.Parent as Patient; if (patient != null) item.PatientMember = patient; Add(item); } return item; } You would also need to think about what happens if you are not using a List... In the scenario above, I had set a setter on the collection like so: internal set { PatientID = value.PatientID; LoadProperty(_patientMemberProperty, value); } I really don't like this setup and I'm not happy with it. Apart from this, it leads you into a StackOverflow when you try to call Save(). If someone can look into this and supply a working sample in code that handles serialization, children and children collections. I would have no problem opening this back up and implementing. For more information with a test solution and database, please take a look at the Google code issue here. Thanks -Blake Niemyjski
In CSLA 4 the Parent properties are public on the base types, so a child shouldn't need to maintain a reference to objects higher in the graph - it can just walk up the graph with this.Parent.Parent.Parent or whatever.
Hello,
Yeah, I looked into this, the problem we are having is that we have a child object (parent -> list -> grand child -> Child property or Parent -> child -> child property that could be pointing back to the parent via a fk relationship etc... We want to set this to have a reference back to the parent.
Thanks
