Hi Stefan Lorenz,
You should use a new IObjectScope instance to retrieve the object which should be updated, update its fields and commit those changes:
(IObjectScope scope = DbScopeProvider.GetNewObjectScope())
User user = scope.Extent<User>().FirstOrDefault();
//update the user instance
If you use the IObjectScope from the data binding statement, the ITransaction.Begin() method will invalidate all the data the grid is bound to. And on ITransaction.Commit() all the data will be invalided and refreshed.
Hope that helps.
