Janis,
I haven't tried this in Flex, but I had a similar problem years ago
with VB, where I wanted the total of all the rows to always be the
last row displayed in the grid. As you know scrolling in the grid is
the problem.
So the easy solution is to create a second grid that has a single row,
and no headers, and position that at the bottom of your main data
grid. The columns will have the same widths as the main grid.
Hope this helps
Andrew
