  • Flex 学习笔记 Datagrid中选中某行时光标定位

    当Datagrid数据多时会出现滚动条,设置selectedIndex位置后,滚动条并不能根据Datagrid选中行的位置进行偏移。

    这时候可使用verticalScrollPosition属性

    AS:
        protected function btn_clickHandler(event:MouseEvent):void
                {
                    dgComplaints.selectedIndex=int(txt.text);
                    dgComplaints.verticalScrollPosition=dgComplaints.selectedIndex;
                }


    MXML:
    <s:TextInput id="txt"/>
        <s:Button label="定位" id="btn" click="btn_clickHandler(event)"/>
        <mx:DataGrid id="dgComplaints" height="100">
