Hi,
Please see following code,
            private function doubleClickHandler(event:MouseEvent):void
                var item:Object = event.currentTarget.selectedItem;// if you know id for grid you can provide that also,
                var index:int = event.currentTarget.selectedIndex;
                Alert.show("Double Clicked item index:" + index);// you have provided it after return so it wont come always!
                if (item != null || index == -1)
                      return ;
                else
                    Alert.show("locations : " + item.@locations);
Hope this will work for u.
Thanks.
