Web2: weblistbox sortcolumn: how to set the sort yourself?

Hi guys, Hi @Greg_O_Lone ,
in the webdatasource class intertface, in the rowdata event, or in the sortedprimarykey event, you have a parameter sortcolumn. it tells you the sort column choosen by the user .
how can I set this sortcolumn at first opening or shown ?
I have a default sort, that is displayed correctly, but at next refresh the sort is scrambled by this sortcolumn that is not the right sort displayed.
is this even possible ?
