HierarchyColumnIndex property sets the display index of the column that will expand the hierarchy. In you need to have 2nd and 3rd level ID, then this should be defined as hierarchical structure and on each level you can rely on having the ID column as hierarchy column.
As a side note, you need to consider using the RadTreeListView for displaying only homogeneous data. For more information you can check our online documentation on TreeListView.
