<mx:Component>
<mx:Button  fontSize="12" label="删除" click="openEditWindow(data)">
<mx:Script>
<![CDATA[
var name:String ="";
override public function set data(value:Object):void
{
super.data = value;
name = value.name;
}
private function openEditWindow(data:Object)
{
  //重写set data 方法 可以获取到你要的名字
   
}

直接data.MyName就可以了,data就是itemRenderer当前行的object,这样data.MyName也就是当前行的MyName.
