Question

我有一个数据网格，其中一列调用自定义的itemEditor，如;

                    <mx:DataGridColumn dataField="city"
                                       width="150" 
                                       headerText="City" 
                                       itemEditor="components.ComboCity" 
                                       editorDataField="city"/>

我的自定义itemEditor看起来像;

    <?xml version="1.0" encoding="utf-8"?>
    <s:MXDataGridItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" 
                              xmlns:s="library://ns.adobe.com/flex/spark" 
                              xmlns:mx="library://ns.adobe.com/flex/mx" 
                              focusEnabled="true">
        <mx:ComboBox id="comboBox"/>
        <fx:Script>
            <![CDATA[
                public var myString:String;
                .
                .
                .

如何从主应用程序传递值myString？

Furher xp：

  myGrid.editedItemRenderer.data.City=myEditor(myGrid.itemEditorInstance).setCity.text;

Answer 2

对我来说最好的解决方案：

<mx:Script>
    <![CDATA[

        import mx.events.DataGridEvent;

        private function itemEditorCreateHandle(event:DataGridEvent):void
        {               
            ComboCity(DataGrid(event.target).itemEditorInstance).myString = "Put here the value";
        }   

    ]]>
</mx:Script>

<mx:DataGridColumn      
    dataField="city"
    width="150" 
    headerText="City" 
    itemEditor="components.ComboCity" 
    itemEditorCreate="itemEditorCreateHandle(event);" 
    editorDataField="city"/>

Answer 3

您始终可以通过调用“outerDocument”属性来引用itemRenderer中的父组件，例如：

myString = outerDocument.componentProperty

Flex：将参数传递给itemEditor
