你得重写 set data方法 你新建下面这个mxml文件,用另一种格式
然后<mx:DataGridColumn headerText="执行日期" width="100" itemEditor="文件名"/>
<?xml version="1.0" encoding="utf-8"?>
<mx:DateField xmlns:mx="http://www.adobe.com/2006/mxml" formatString="YYYY.MM.DD">
<mx:Script>
<![CDATA[
import mx.controls.listClasses.BaseListData;
import mx.controls.listClasses.ListData;
import mx.events.FlexEvent;
import mx.controls.dataGridClasses.DataGridListData;

private var _data:Object;
private var _listData:BaseListData;
private var selectedDateSet:Boolean;

override public function get listData():BaseListData
{
return _listData;
}

/**
* @private
*/
override public function set listData(value:BaseListData):void
{
_listData = value;
}

override public function set data(value:Object):void
{
var newDate:Date;

_data = value;

var str:String=_data[DataGridListData(_listData).dataField];
if(str==null)
str="";
newDate = DateField.stringToDate(str,"YYYY.MM.DD");
if (!selectedDateSet)
{
selectedDate = newDate;
selectedDateSet = false;
}

dispatchEvent(new FlexEvent(FlexEvent.DATA_CHANGE));
}

override public function get data():Object
{
return _data;
}

Answer 2

方法有很多，提供一种我所使用的方法
将一行的所有元素作为一个类的属性
实例化类后，加入集合或数组将数组赋给table的dataprovide属性
然后再每一列赋予元素属性即可，flex会自动进行递归数据绑定的

已经试过好多方法了，都已经贴出全部代码了，能改好通过发出来吗，谢谢

Answer 3

flex中，在DateField上只能显示年月日，我现在想添加一个控件，使其能够显示formatString=

追问

会的话改好发出来，通过就给分，帮帮忙，其他方法就说明详细操作，编程刚接触不太懂
