I'm afraid that parent/child selection will not work for this column - you will get only the behavior similar to RadGridView. Header CheckBox for select/deselect of all items and CheckBoxes for individual items selection.
I see that your scenario is more complex and I would like to suggest you to create your custom column where you can embed desired logic. For more info about custom columns you can check this demo.
All the best,
