Ms Flexgrid Ordering

Hello everybody,

I got a problem ordering data in a msflexgrid control. Let's say that we have a flexgrid like the one below

Date |Head1|Head2|Head3|Head4|Head5
2011 |0 |300 |40 |0 |200

i want to reorder it in a new msflexgrid like this

Date |Head2|Head5|Head3|Head1|Head4
2011 |300 |200 |40 |0 |0

from the maximum value to the minimum.

any idea ... I am stuck on this ???
