Flex DataGrid 可编辑 控制输入值的长度——maxchars

使用itemRenderer自定义，利用TextInput的maxchars。

代码如下：

<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" initialize="init()"> <mx:Script> <!--[CDATA[ import mx.collections.*; import mx.events.CollectionEvent; private var DGArray:Array = [ {Artist:'Pavement', Album:'Slanted and Enchanted', Price:11.99}, {Artist:'Hotdog', Album:'Brighten the Corners', Price:21.99}]; [Bindable] public var initDG:ArrayCollection; public function init():void { initDG=new ArrayCollection(DGArray); } ]]--> </mx:Script> <mx:DataGrid id="giftList" height="100" width="100%" dataProvider="{initDG}" > <mx:columns> <mx:DataGridColumn dataField="Artist" /> <mx:DataGridColumn dataField="Album" > <mx:itemRenderer> <mx:Component> <mx:HBox> <mx:TextInput id="amount" text="{data.Album}" width="190" maxChars="10"/> </mx:HBox> </mx:Component> </mx:itemRenderer> </mx:DataGridColumn> <mx:DataGridColumn dataField="Price" /> </mx:columns> </mx:DataGrid> </mx:Application>
