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 :)

Hello everyone,
I would like to trigger a column sort
programmatically, as if the user
had clicked the column header. I have read many
posts, and LiveDocs
about this topic, and I did not like the solutions
presented there. My
grid has plenty of calculated display content
(labelFunctions and
custom itemRenderers), many columns require custom
sortFunctions. I
would like to use these functions exactly as they
are, just without
asking the user to click anything.
I came up with one way, which is to dispatch a
HEADER_RELEASE event (see
below utilized after a column drag), but that's a
bit like accelerating
a car by dispatching a PUSH_PEDAL event instead of
controlling the
engine directly - if that analogy makes any sense.
private function reGroup(event : IndexChangedEvent )
: void
{
dgItems.dispatchEvent(new
DataGridEvent(DataGridEvent.HEADER_RELEASE,false,false,event.newIndex));
}
What I was hoping for, would be a method like:
dataGrid.sortItemsBy(
ColumnIndex, [ASC|DESC] ) or dataGrid.sortItemsUsing
(
sortCompareFunction, [ASC|DESC] ). Some of that was
mentioned in the
early posts on this list, but it seemed to be
related to Flex 1.5
Thanks for any help, or input
