Flex dataGrid 用measureHeightOfItems 去掉竖直滚动条

当数据很多的时候

Flex Datagrid 会自动给表格加上滚动条

?

有时候我们需要去除滚动条 如何做呢？

?

添加对窗体的updateComplete 或者createComplte事件

或者对dataGrid的dataprovider添加监听事件

?

后者会占用占用稍微少一点的资源

?

然后对datagrid的高度赋值

dg.height = dg.measureHeightOfItems(0, dgDataProvider.length) + dg.headerHeight

<mx:vbox xmlns:mx="http://www.adobe.com/2006/mxml">        <mx:script>                <![CDATA[                        import mx.collections.ArrayCollection;                         [Bindable]>                   public var text:String = "";                         [Bindable]                        public var gridData:ArrayCollection;                         public function handleCreationComplete(e:Event):void                        {                                trace("finished");                                //+2 for 1 pixel border at top and bottom                                dg.height=dg.measureHeightOfItems(0,gridData.length)+dg.headerHeight+2;                        }                ]]>        </mx:script>        <mx:datagrid id="dg">                editable="true" variableRowHeight="true" width="460"                dataProvider="{gridData}" creationComplete="handleCreationComplete(event)">            <mx:columns>                <mx:datagridcolumn datafield="name" headertext="Name">                <mx:datagridcolumn datafield="phone" headertext="Phone">                <mx:datagridcolumn datafield="email" headertext="Email">            </mx:datagridcolumn>        </mx:datagridcolumn></mx:datagridcolumn></mx:columns></mx:datagrid></mx:vbox>
