Flex AdvancedDataGrid 分层显示

AdvancedDataGrid 实际上是增强版的DataGrid，提供更强大的定制显示功能。

 

1、以树状结构显示数据

 

 

 

<?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" creationComplete="application1_creationCompleteHandler(event)">
	<s:layout>
		<s:BasicLayout/>
	</s:layout>
	<fx:Script>
		<![CDATA[
			import mx.collections.ArrayCollection;
			import mx.collections.HierarchicalData;
			import mx.events.FlexEvent;
			
			//children为array，指出DataGrid的层级关系
			public var dp:ArrayCollection = new ArrayCollection([
				{name:"jobs",email:"[e-mail]",children:[{name:"tom",email:"[e-mail]"}]}
				,{name:"marry",email:"[e-mail]"}
			]);
			
			protected function application1_creationCompleteHandler(event:FlexEvent):void
			{
				// TODO Auto-generated method stub
			
				var fd:HierarchicalData = new HierarchicalData;
				fd.source = dp;
				dd.dataProvider = fd;
				
			}

		]]>
	</fx:Script>
	<fx:Declarations>
		<!-- 将非可视元素（例如服务、值对象）放在此处 -->
	</fx:Declarations>
	
	<mx:AdvancedDataGrid id="dd">
		<mx:columns>
			<mx:AdvancedDataGridColumn dataField="name" headerText="姓名">
				
			</mx:AdvancedDataGridColumn>
			<mx:AdvancedDataGridColumn dataField="email" headerText="邮箱">
				
			</mx:AdvancedDataGridColumn>
		</mx:columns>
	</mx:AdvancedDataGrid>
</s:Application>

 2、或者数据是动态获取的，你可以这样拼凑数据

 

 

<?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" creationComplete="application1_creationCompleteHandler(event)">
	<s:layout>
		<s:BasicLayout/>
	</s:layout>
	<fx:Script>
		<![CDATA[
			import mx.collections.ArrayCollection;
			import mx.collections.HierarchicalData;
			import mx.events.FlexEvent;
			
			//children为array，指出DataGrid的层级关系
			public var dp:ArrayCollection = new ArrayCollection([
				{name:"dd",email:"[e-mail]"}
				,{name:"lp",email:"[e-mail]"}
			]);
			
			protected function application1_creationCompleteHandler(event:FlexEvent):void
			{
				// TODO Auto-generated method stub
			
				var childrens:Array = new Array();
				childrens.push({name:"ddlp",email:"[e-mail]"});
				
				dp.getItemAt(0).children = childrens;   //children 指定层级关系
				
				var fd:HierarchicalData = new HierarchicalData;
				fd.source = dp;
				dd.dataProvider = fd;
				
			}

		]]>
	</fx:Script>
	<fx:Declarations>
		<!-- 将非可视元素（例如服务、值对象）放在此处 -->
	</fx:Declarations>
	
	<mx:AdvancedDataGrid id="dd">
		<mx:columns>
			<mx:AdvancedDataGridColumn dataField="name" headerText="姓名">
				
			</mx:AdvancedDataGridColumn>
			<mx:AdvancedDataGridColumn dataField="email" headerText="邮箱">
				
			</mx:AdvancedDataGridColumn>
		</mx:columns>
	</mx:AdvancedDataGrid>
</s:Application>
