How to sort the groupings ?

[GoogleCodeExporter]

Hi, I am using this row grouping so far, I like it, so everything is working 
fine, the only thing I wanted is a way to sort the grouping asc and desc..

i know I can change the sGroupingColumnSortDirection: to what ever order, but I 
will like the user to be able to change with a select drop down..

here are some infos
