C#: listview, how to sort items with subitem

C#

I have a listview with items - everything fine.
But in some cases, these items could have "child" items.

If you check the screenshot attached you can see that still, everything is fine. (child items has the pie diagram.)

My main problem starts when I want to use the column header to sort the items.
When I do so, the sub/child items won't be under the parent item anymore.

Is there a relatively easy solution for this?

What I have tried:

- tried to create a treeview in the listview, but that wasn't really the result I waited for as I need the child items also clickable as the main items...
