HOWTO: Move rows up/down by code

Hi;

I've a tree like report control and since built-in drag&drop does not support to rearrange rows in this mode, I want to move record up/down by code.
But I can't find out how this has to be implemented.
I tried this code to move a row up by one row:

CXTPReportRow* Row=Report_.GetFocusedRow();     Report_.GetRecords()->MoveRecord(Row->GetIndex()-1, Row->GetRecord(), TRUE);     Report_.Populate();

but nothing happens.

Any help is very welcome...

CXTPReportRow* Row=Report_.GetFocusedRow(); Report_.GetRecords()->MoveRecord(Row->GetRecord()->GetIndex()-1, Row->GetRecord(), TRUE); Report_.Populate();
