flex 4 在datagrid中 添加了一个checkbox 如何获取所选行的值

public class InitData
{
public function getColumnsArray():Array
{
var columnsArray:Array = null;
var _checkBoxCloumn:CheckBoxColumn = new CheckBoxColumn();
_checkBoxCloumn.dataField = "isSelected";
_checkBoxCloumn.headerRenderer = new ClassFactory(CheckBoxHeaderRenderer);
_checkBoxCloumn.itemRenderer = new ClassFactory(CheckBoxItemRenderer);
_checkBoxCloumn.width = 30;
_checkBoxCloumn.sortable = false;
_checkBoxCloumn.draggable = false;

var _nameColumn:DataGridColumn = new DataGridColumn();
_nameColumn.headerText = "姓名";
_nameColumn.dataField = "name";

var _telColumn:DataGridColumn = new DataGridColumn();
_telColumn.headerText = "电话";
_telColumn.dataField = "phone";

var _emailColumn:DataGridColumn = new DataGridColumn();
_emailColumn.headerText = "邮件";
_emailColumn.dataField = "email";

columnsArray =new Array(_checkBoxCloumn,_nameColumn,_telColumn,_emailColumn);
return columnsArray;
}

public function getDataArray():ArrayCollection
{
var dataArray:ArrayCollection = new ArrayCollection;
dataArray.addItem({isSelected:false,name:'Christina Coenraets',phone:'555-219-2270',email:''});
dataArray.addItem({isSelected:false,name:'Joanne Wall',phone:'555-219-2012',email:''});

dataArray.addItem({isSelected:false,name:'God Win',phone:'555-219-2005',email:'godwin@fictitious.com'});
return dataArray;
}

可以在 <mx:DataGrid id="dg" x="10" y="0" width="524" height="236">
<mx:DataGridColumn headerText="内容"
dataField="message" />
</mx:columns>
获取，dg.selecteditem.message
