TLVOwnerDataHintEvent is the type of a list view's OnDataHint event handler.
TLVOwnerDataHintEvent = procedure (Sender: TObject; StartIndex, EndIndex: Integer) of object;
(Sender: TObject; StartIndex, EndIndex: Integer) ( TLVOwnerDataHintEvent)();
StartIndex is the first item in the range for which the OnData event may occur.
EndIndex is the last item in the range for which the OnData event may occur.
Use the index information to update the items in the range before the OnData event occurs.
