Advertisement
Hierarchical data is a structure of parent and child items.

Displaying hierarchical XML data in AdvancedDataGrid:

Hierarchical data is a structure of parent and child items. In this example we use a XMLList for providing a hierarchical data to the AdvancedDataGrid. You set the dataField property like dataField="@Course". You will import the two packages :

import mx.collections.HierarchicalData;

import mx.collections.XMLListCollection;

Example:

<?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"

<fx:Declarations>

<fx:XMLList id="student" xmlns="">
