下面是一个在datagrid中设置超链接的一个小例子：

DataGridLink.mxml

<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" preinitialize="preinit();" creationComplete="creationComplete();" viewSourceURL="srcview/index.html"> <mx:XMLList id="employees"> <employee> <name>Christina Coenraets</name> <phone>555-219-2270</phone> <email>ccoenraets@fictitious.com</email> </employee> <employee> <name>Joanne Wall</name> <phone>555-219-2012</phone> <email>jwall@fictitious.com</email> </employee> <employee> <name>Maurice Smith</name> <phone>555-219-2012</phone> <email>maurice@fictitious.com</email> </employee> <employee> <name>Mary Jones</name> <phone>555-219-2000</phone> <email>mjones@fictitious.com</email> </employee> </mx:XMLList> <mx:Script>  </mx:Script> <mx:DataGrid top="5" left="5" right="5" bottom="5" dataProvider="\{employees\}" id="queryDataGrid"> </mx:DataGrid> </mx:Application>

LinkButtonDynamicEvent.as

UrlLinkRenderer.as
