Currently Jun 2014, when saving new data on hierarchy (parent/child) grid, there is no possible way to save the header data, get the pk of the header and pass the pk to child data and save the child data. I suggest to add a feature to auto save both parent and child data when user click save button when creating new data. Basically do ajax save for the parent, on success pass header's pk to do ajax save for child.
Hello,
If you have a self-referencing hierarchy data I would suggest using the TreeList component instead of Grid.

That said, if you would like to save all hierarchy levels in a Grid with a single button you can utilize the approach demonstrated in the Knowledge Base article below. It is using the jQuery widget, however the relevant SaveAll JavaScript method is applicable also for the MVC wrappers.
