1、设计思路
（1）新建一个DataGrid，在其中最后一列加入三个按钮：新增、修改和删除；
（2）点击新增按钮，可以将表格新增一行；
（3）单击“修改”按钮，可以修改表格中该行的一些属性；
（4）单击“删除”按钮，会将表格中该行删除。
2、实现步骤
（1）新建一个应用程序，DataGrid.mxml
DataGrid.mxml：
复制代码 代码如下:
?xml version="1.0" encoding="utf-8"?>
s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
s:layout>
s:BasicLayout/>
/s:layout>
fx:Declarations>
!-- 将非可视元素（例如服务、值对象）放在此处 -->
/fx:Declarations>
fx:Script>
![CDATA[
import mx.collections.ArrayCollection;
[Bindable]
//表格数据源绑定
private var grid:ArrayCollection = new ArrayCollection([
{number:"2014010101",name:"张三",sex:"男",age:"19"},
{number:"2014010102",name:"李思",sex:"女",age:"20"},
{number:"2014010103",name:"蔡华",sex:"男",age:"21"},
{number:"2014010104",name:"牛耳",sex:"女",age:"22"},
{number:"2014010105",name:"兆司",sex:"男",age:"18"},
{number:"2014010106",name:"胡柳",sex:"女",age:"19"},
{number:"2014010107",name:"刘斯",sex:"男",age:"20"},
{number:"2014010108",name:"孙阳",sex:"女",age:"22"},
{number:"2014010109",name:"郑武",sex:"男",age:"21"},
{number:"2014010110",name:"王雪",sex:"女",age:"20"},
{number:"2014010111",name:"胡柳",sex:"女",age:"19"},
{number:"2014010112",name:"刘斯",sex:"男",age:"20"},
{number:"2014010113",name:"孙阳",sex:"女",age:"22"},
{number:"2014010114",name:"郑武",sex:"男",age:"21"},
{number:"2014010115",name:"王雪",sex:"女",age:"20"}
]);

（2）新建一个新增窗口组件，ChildWindow.mxml
ChildWindow.mxml：
复制代码 代码如下:
?xml version="1.0" encoding="utf-8"?>
s:TitleWindow xmlns:fx="http://ns.adobe.com/mxml/2009"

close="closeHandler(event)" title="新增窗口">
s:layout>
s:BasicLayout/>
/s:layout>
fx:Script>
![CDATA[
import mx.events.CloseEvent;
import mx.managers.PopUpManager;
/*关闭按钮函数*/
protected function closeHandler(event:CloseEvent):void
{
PopUpManager.removePopUp(this);
}
/*取消按钮函数*/
protected function cancelHandler(event:MouseEvent):void
{
PopUpManager.removePopUp(this);
}
]]>
/fx:Script>
fx:Declarations>
!-- 将非可视元素（例如服务、值对象）放在此处 -->
/fx:Declarations>
mx:VBox width="100%" height="100%" horizontalAlign="center">
mx:Form borderStyle="solid" borderColor="#CCCCCC" width="100%">
mx:FormHeading label="新增界面" fontSize="14"/>
mx:FormItem label="学号：">
s:TextInput id="stuNo" width="200"/>
/mx:FormItem>
mx:FormItem label="姓名：">

/mx:FormItem>
mx:FormItem label="性别：">
s:TextInput id="stuSex" width="200"/>
/mx:FormItem>
mx:FormItem label="年龄：">

/mx:FormItem>
/mx:Form>
mx:HBox width="100%" height="25">
s:Label width="60"/>
s:Button label="新增"/>
s:Label width="48"/>
s:Button label="取消" click="cancelHandler(event)"/>
/mx:HBox>
/mx:VBox>
/s:TitleWindow>
（3）新建一个修改界面组件，UpdateWindow.mxml
UpdateWindow.mxml：
复制代码 代码如下:
?xml version="1.0" encoding="utf-8"?>
s:TitleWindow xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300"
close="closeHandler(event)" title="修改窗口">

import mx.events.CloseEvent;
import mx.managers.PopUpManager;

protected function closeHandler(event:CloseEvent):void
{
PopUpManager.removePopUp(this);
}
/*取消按钮函数*/
protected function cancelHandler(event:MouseEvent):void
{
PopUpManager.removePopUp(this);
}
]]>
/fx:Script>
fx:Declarations>
!-- 将非可视元素（例如服务、值对象）放在此处 -->

3、设计结果
（1）初始化时
