Retrieving Key from array

Question

Hi
I need a dynamic way of retrieving all the "keys" from a array.
Found this which is exactly what I need but doesn't work as expected in my case:
var myObject:Object = {key1:"value1",key2:"value2"}
for (var s:String in myObject)
trace("key:",s,"value:",myObject[s]);
//key: key2 value: value2
//key: key1 value: value1
My case:
var testArray:Array = new Array()
testArray = DG1.dataProvider.toArray() // create array from dataprovider
I've tested this array and it performs "correctly" as an array but when I try the above mentioned method it traces as follows:
key: 0 value: [object Object] (key not being what I need)
What I need:
dgArr.push({partNo:event.target.data['partNo'+i],description:event.target.data['descriptio n'+i],cost:event.target.data['cost'+i]});               
trace (????) //outputs = partNo, description, cost etc...
Thanks for any help.

Answer 1

your dataprovider values are also objects.  use:
function listF(dp:DataProvider):void{
for(var i:int=0;i<dp.length;i++){
for(var s:String in dp.getItemAt(i)){
trace(s,dp.getItemAt(i)[s]);
