you could actually, by subclassing the datagrid class
and exposing the private method sortByColumn - the
method called by header release event handler in the
datagrid as class file. However, I am more inclined to
sticking with adobe's private implementation of this
class and do the sorting instead at the dataprovider
level; that way you get finer control over the sorting
process.. then update the datagrid display :)
