Flex DataGrid之一（定义数据源直接赋值）

1.第一种在datagrid组件中直接赋值。<mx:DataGrid x="210" y="184" dataProvider="{myDP}">

<?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">
	
	<fx:Script>
		<![CDATA[
 
			import mx.collections.ArrayCollection;

	[Bindable]  private var myDP:ArrayCollection = new ArrayCollection([
	{Artist:'Pavement',Album:'Slanted and Enchanted',Price:'(11.99)'},{Artist:'Pavement',Album:'Crooked Rain,Crooked Rain',Price:'(10.99)'},Album:'Wowee Zowee',Price:'(12.99)'},Album:'Brighten the Corners',Album:'Terror Twilight',Price:'(11.99)'}
	]);

		]]>
	</fx:Script>

	
	<fx:Declarations>
		<!-- 将非可视元素（例如服务、值对象）放在此处 -->
	</fx:Declarations>
	<mx:DataGrid x="210" y="184" dataProvider="{myDP}">
		<mx:columns>
			<mx:DataGridColumn headerText="Artist" dataField="Artist"/>
			<mx:DataGridColumn headerText="Album" dataField="Album"/>
			<mx:DataGridColumn headerText="Price" dataField="Price"/>
		</mx:columns>
	</mx:DataGrid>
 
</s:Application>

2.第二种赋值方式：datagrid.dataProvider=myDP;

<?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"
			    initialize="init()"
			   >
	
	<fx:Script>
		<![CDATA[
 
			import mx.collections.ArrayCollection;

			
	[Bindable]  private var myDP:ArrayCollection = new ArrayCollection([
	{Artist:'Pavement',Price:'(11.99)'}
	]);
    
	function init(){
			
		datagrid.dataProvider=myDP;
	}	
			
			
		]]>
	</fx:Script>

	
	<fx:Declarations>
		<!-- 将非可视元素（例如服务、值对象）放在此处 -->
	</fx:Declarations>
	<mx:DataGrid x="210" y="184" id="datagrid" >
		<mx:columns>
			<mx:DataGridColumn headerText="Artist" dataField="Artist"/>
			<mx:DataGridColumn headerText="Album" dataField="Album"/>
			<mx:DataGridColumn headerText="Price" dataField="Price"/>
		</mx:columns>
	</mx:DataGrid>
 
</s:Application>
