Multi column sorting

Question

I am wondering if it is possbile to sort data grids in multi
columns?? For example lets say the data grid simply looks like
this:
Name
Date
Art 10/29/06
Chris 12/02/04
Bob 02/21/07
Bo 08/08/05
And i want to sort it in abc order first then within that
sort(abc order) have does be sorted again by date so that A's will
stay together, B's and so on...Is this possible and if so how?
Thanks for all the help

Answer 1

here is what i have...it crashes after the first click....
rivate function ctrlCheck(ke:KeyboardEvent):void // checks to
see if the ctrl key is pressed to do a multicolumn sort.
if( ke.keyCode == 17) ctrlChecker =true;
else ctrlChecker = false;
private function resortColumns(le:ListEvent):void //if there
is more than one page of results resort the columns and requery,
else just resort
colSortedOn = new String("");
var sortDirection:String = new String("");
var s:Sort=new Sort();
var count:int=0;
var arr:Array=new Array();
if(le.rowIndex == 0)//get the column sorted on and attach
that to the query and requery
if(ctrlChecker==true)
while(ctrlChecker==true)//while the user is still holding
the ctrl key
colSortedOn =
DataGridColumn(datagrid1.columns[le.columnIndex]).dataField.toString();
if(DataGridColumn(datagrid1.columns[le.columnIndex]).sortDescending)
sortLoadDirection = true;
else
sortLoadDirection = false;
arr[count]=new SortField(colSortedOn, true,
sortLoadDirection)
count ++;
for(var i:int =0; i<arr.length; i++)
s.fields
=arr
datagrid1.dataProvider.sort= s;
datagrid1.dataProvider.refresh();
else //there is no sort order taking place, the item click
was something else entirely
parentDocument.sortCheck = 1;
}
