Like this:
Code: Select all
ParentObject po = new ParentObject();
ChildObject co = new ChildObject();
po.Childobjects.add(co);
db.ParentObjects.insertOnSubmit(po);
db.SubmitChanges();But that doesnt't work, i cannot add a childobject to a parentobject.
My workaround at the moment is the following:
Code: Select all
childobject.insertonsubmit(co);
parentobject.insertonsubmit(po);
db.submitchanges();
