Unsort a DataGrid Column

Question

short version:
Is there a clever way to "un-sort" a datagrid column so the
Column and Grid will go back to the original pre-sorted state?--not
just remove the ability to sort.
long-winded background:
I'm using a ComboBox to toggle between report views (which
are displayed in a DataGrid). I have 2 views: the All View and the
Grouped View. The trouble I'm having is that once a column in my
DataGrid gets sorted by a User (which is desirable) in the All
View, then when the User toggles to the Grouped View the sort is
still in place for the column (not desirable). Upon toggle (via
ComboBox change event), I first clear out the DataProvider of all
data, then I'm setting the "sortable" property of the individual
columns and the DataGrid to be 'false' and then I'm repopulating
the DataProvider with fresh data. The result is that the ability to
sort the datagrid is indeed taken away from the User, but the new
data still appears sorted by the column.
dataAC.removeAll(); // ArrayCollection DataProvider to my
DataGrid
// Grouped View
for (var j:int=0;j<graphDG.columns.length;j++) {
var dgc: DataGridColumn = graphDG.columns[j] as
DataGridColumn;
dgc.sortable = false;
graphDG.sortableColumns = false;
...// refill dataAC

Hello feldt12,
This will clear the sort:
ListCollectionView(dataGrid.dataProvider).sort = null;
ListCollectionView(dataGrid.dataProvider).refresh();
Thanks,
Philip
