Flex/actionscript:在AdvancedDataGrid上使用dataDescriptor

层次结构数据有一个childrenField属性,您可以使用该属性“告诉”控件在何处查找分支。

从Adobe live docs on AdvancedDataGrid示例中,可以看到可以将AdvancedDataGrid的dataProvider设置为GroupingCollection实例,以便为数据创建一些组。沿着类层次结构往下看,有层次结构数据,在AdvancedDataGrid上设置dataProvider时需要使用这些数据。示例(很抱歉使用数组而不是一个XML):

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical">
    <mx:Array id="dianaSerfes">
        <mx:Object name="geen" surname="zod" />
    </mx:Array>
    <mx:Array id="xySerfs">
        <mx:Object name="sdf" surname="sdfsdgd" />
    </mx:Array>
    <mx:Array id="johnSerfs">
        <mx:Object name="jack" surname="the ripper" />
        <mx:Object name="diana" surname="bloom" serfs="{dianaSerfes}"/>
    </mx:Array>
    <mx:Array id="myData">
        <mx:Object name="xy" surname="zzz" serfs="{xySerfs}" />
        <mx:Object name="blue" surname="zed" />
        <mx:Object name="John" surname="smith" serfs="{johnSerfs}" />
    </mx:Array>
    <mx:AdvancedDataGrid width="100%" height="100%">
        <mx:dataProvider>
            <mx:HierarchicalData id="hd" source="{myData}" childrenField="serfs" />
        </mx:dataProvider>
        <mx:columns>
            <mx:AdvancedDataGridColumn dataField="name" />
            <mx:AdvancedDataGridColumn dataField="surname" />
        </mx:columns>
    </mx:AdvancedDataGrid>
</mx:Application>
