Java code

[解决办法]
没太理解楼主的用意；一般很少这么用吧
可以给Grid注册focusin事件通过选中项获取值如

Assembly code

<?xml version="1.0"?><!-- DataGrid control example. --><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">    <mx:XMLList id="employees">        <employee>            <name>Christina Coenraets</name>            <phone>555-219-2270</phone>            <email>ccoenraets@fictitious.com</email>            <active>true</active>        </employee>        <employee>            <name>Joanne Wall</name>            <phone>555-219-2012</phone>            <email>jwall@fictitious.com</email>            <active>true</active>        </employee>        <employee>            <name>Maurice Smith</name>            <phone>555-219-2012</phone>            <email>maurice@fictitious.com</email>            <active>false</active>        </employee>        <employee>            <name>Mary Jones</name>            <phone>555-219-2000</phone>            <email>mjones@fictitious.com</email>            <active>true</active>        </employee>    </mx:XMLList>    <mx:Panel title="DataGrid Control Example" height="100%" width="100%"         paddingTop="10" paddingLeft="10" paddingRight="10">        <mx:Label width="100%" color="blue"            text="Select a row in the DataGrid control."/>        <mx:DataGrid id="dg" width="100%" height="100%" rowCount="5" dataProvider="{employees}">            <mx:columns>                <mx:DataGridColumn dataField="name" headerText="Name"/>                <mx:DataGridColumn dataField="phone" headerText="Phone"/>                <mx:DataGridColumn dataField="email" headerText="Email"/>            </mx:columns>        </mx:DataGrid>        <mx:Form width="100%" height="100%">            <mx:FormItem label="Name">                <mx:Label text="{dg.selectedItem.name}"/>            </mx:FormItem>            <mx:FormItem label="Email">                <mx:Label text="{dg.selectedItem.email}"/>            </mx:FormItem>            <mx:FormItem label="Phone">                <mx:Label text="{dg.selectedItem.phone}"/>            </mx:FormItem>        </mx:Form>            </mx:Panel></mx:Application>

很简单的啦，data.MyName就可以了
[解决办法]
<mx:DataGrid   dataProvider="{taskListArr}">
<mx:columns>
<mx:DataGridColumn headerText="任务名" dataField="MyName" headerStyleName="centered"/>
<mx:DataGridColumn headerText="操作" width="70" resizable="false" headerStyleName="centered">
<mx:itemRenderer>
<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
   
}

</mx:Script> 
</mx:Button>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
</mx:columns>
</mx:DataGrid>
[解决办法]
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.
