Does GroupView work in the TListView in OwnerData mode?

Question

I'm trying to implement an "Arrange by" feature for a TListView in Delphi XE2. In the form designer (if I turn off OwnerData) I can get groups to show up and add items to them

However, if I try setting

 procedure TMyForm.LVData(Sender: TObject; Item: TListItem);
  Item.GroupID := 0;

None of my list items are placed in the group.

Perfunctory information you may also want to know

1. ListView is in report mode
2. Themes are enabled for application (running on Windows 7)
3. GroupView is enabled
4. Yes, I have a group with an ID of 0

Answer 1

Upon further googling, the answer is no.

The following messages are not supported under the LVS_OWNERDATA style: LVM_ENABLEGROUPVIEW, LVM_GETITEMTEXT, LVM_SETTILEINFO, and LVM_MAPIDTOINDEX.

That would be some helpful info in the Embarcadero Help file and Delphi IDE.

(maybe uncheck groupview when owner data is checked, eh?)
