I have a geographic "Region" Row Group that uses a "Recursive parent" field to generate a recursive hierarchy. I set the Group's ToggleItem to the group's textbox to enable drill-down within the group as shown below. However I also want to be able to Toggle rows using cells in the Parent "Risk" Row Group. How can I setup this Tablix so that the entire Recursive Hierachy Group under a parent row can be collapsed and expanded by its parent value, without losing the ability to toggle within the Region group?
