无法确定何时选择子行，以及如何获取所选数据

I have dragged a WebHierarchicalDataGrid to the page and have told it not to autogenerate bands or autogenerate columns. Enable Ajax is unchecked. Via codebehind, I manually created the columns on the grid for both the parent and child tables. I have double clicked on RowSelectionEvent to test to see if the event ever fires. When I select a row from a child table, the event never fires. Is there a child row selection event that I am not aware of? If not can someone show me the correct way to get field data from a child row that was selected. I have been working on this for several days and I am pretty frustrated that there seems to be no easy way to accomplish this task. Any help is GREATLY appreciated.
