在单击填充我的数据网格时，我有一个“获取数据”按钮。我想同时用数据网格的列名填充组合框。在生成调用时，结果将存储在最后一个结果中，然后我将其存储到数组中。

<fx:Script>
    <![CDATA[
        import mx.collections.ArrayCollection;
        import mx.controls.Alert;
        import mx.events.FlexEvent;
        import mx.events.ListEvent;
        import mx.rpc.events.ResultEvent;

        import services.ServiceManager;

        import spark.events.IndexChangeEvent;


        [Bindable] public var ArrColl_selectOptionComboBox:ArrayCollection = new ArrayCollection;
        [Bindable] public var SelectOption:ArrayCollection = new ArrayCollection;

        [Bindable] public var mainArrColl:ArrayCollection = new ArrayCollection;
        [Bindable] public var DGDataProvider:ArrayCollection = new ArrayCollection;
        [Bindable] public var DGDataProvider1:ArrayCollection = new ArrayCollection;

        public function clear():void
        {
            DGDataProvider = new ArrayCollection;
        }

        //clicking on the Get Data button to retrieve from the Jiraissue
        protected function button_clickHandler(event:MouseEvent):void
        {
            getAllJiraissueResult2.token=jiraissueService1.getAllJiraissue();


        }

        protected function getAllJiraissueResult2_resultHandler(event:ResultEvent):void
        {
            mainArrColl = getAllJiraissueResult2.lastResult as ArrayCollection;
            DGDataProvider = mainArrColl;



        }









    //protected function Combobox_Option_changeHandler(event:ListEvent):void
        //{

                //myLabel.text = "You selected: " +  ComboBox(event.target).selectedItem.label;

                    //Value.prompt="Select Value";
                    //Value.selectedIndex=-1; // reset so prompt shows





        //}

        ]]>

如果我正确理解了您的问题，您只想在获取数据后使用 datagrid 的列名填充您的组合框。如果是这样，您可以使用网格的“列”属性作为组合框的数据提供者。“labelField”属性应设置为“headerText”。清除网格后，将 cb 的 dataprovider 设置为 null。

这是一个简单的代码：

<?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;
        import mx.events.CollectionEvent;

        [Bindable]private var dp:ArrayCollection = new ArrayCollection([
            {artist:"Pavement",         album:"Slanted and Enchanted",  year:"2010",    price:39.1},
            {artist:"ABBA",             album:"Ring Ring",              year:"1973",    price:45.2},
            {artist:"The Betles",       album:"Please Please Me",       year:"1963",    price:29.1}]);

        private function onBtnLoad():void
        {
            myGrid.dataProvider = dp;

            cbCategories.dataProvider = myGrid.columns;
            cbCategories.labelField = "headerText";
        }

        private function onBtnReset():void
        {
            myGrid.dataProvider = null;

            cbCategories.selectedIndex = -1;
            cbCategories.dataProvider = null;
        }
