I think my problems are something to do with the difference between

TCustomRVData and TCustomRVFormattedData. The pointer I have to the

RVData is a TCustomRVData; however, SetSelectionBounds seems to be a

method of TCustomRVFormattedData. Could you explain the difference? I

can cast RVData to a TCustomRVFormattedData, but the SetSelection

doesn't seem to work.

Thanks,

Martin
