我有一个数据网格,这个网格的数据提供者是RPC调用的结果。结果集具有以下结构:
Array
[0]->Object #1
[one] => 1
[two] => 1
[three] => Object #2
[apple1] = > Object #3
[color] => red
[rate] => 20
[apple2] => Object #4 ( the number of apples is dynamic, apple3,apple4 .. and so on)
[color] => blue
[rate] => 100
等等......所以苹果对象的数量会因其动态而有所不同。如何在数据网格中显示此数据?
我看到很多关于创建“嵌套DataGridColumn”类的文章......像这样:
http://active.tutsplus.com/tutorials/flex/working-with-the-flex-datagrid-and-nested-data-structures/
这有帮助,但我的数据的问题是一些索引(如apple1,apple2等)是动态的。我如何包含这些?

我得到了这个工作。
我使用了内联项呈示器并使用foreach循环来遍历包含动态嵌套对象的对象。这是我的代码:
<mx:DataGridColumn headerText="Roles Assigned">
<mx:itemRenderer>
<fx:Component>
<mx:VBox creationComplete="box1_creationCompleteHandler()">
<fx:Script>
<![CDATA[
import com.pm.modules.events.UpdateDBEvent;
import mx.containers.HBox;
import mx.controls.Alert;
import mx.controls.Label;
import mx.controls.LinkButton;
import mx.events.FlexEvent;
protected function box1_creationCompleteHandler():void
{
for each(var temp:Object in data.roles){
var hgrp:HBox = new HBox();
hgrp.autoLayout = false;
var lbl:Label = new Label();
lbl.text = temp.rname;
var lb:LinkButton = new LinkButton();
lb.label = 'X';
lb.id = temp.rid.toString();
lb.focusEnabled = true;
lb.addEventListener(MouseEvent.CLICK,handleClick);
hgrp.addElement(lbl);
hgrp.addElement(lb);
this.addElement(hgrp);
}
}
protected function handleClick(event:MouseEvent):void{
dispatchEvent(new UpdateDBEvent(UpdateDBEvent.ON_DELETE_PRIVILEGE_ROLE_MAP,0,0,0,event.target.id,0,true));
}
]]>
</fx:Script>
</mx:VBox>
</fx:Component></mx:itemRenderer></mx:DataGridColumn>

您使用的服务器端技术是什么? BlazeDs / amfphp,还有什么?
你应该做的是将你的苹果包装在一个ArrayCollection中然后你应该没问题。
[0]->RPC Result
[one] => 1
[two] => 1
[three] => ArrayCollection
[1] = > Apple#3
[color] => red
[rate] => 20
[2] => Apple #4 ( the number of apples is dynamic, apple3,apple4 .. and so on)
[color] => blue
[rate] => 100
