How can I outline the row or column of the current cell with special formatting?

See the DbfBrows sample (dbfbrvw.cpp).  DbfBrows provides an example how to outline the cells of the current row.  The current row will be outlined with a special background color and text color.  When the end-user moves through the grid, the cells of the previous row will be reset to their default appearance and the new row will be highlighted.
