Question

我有一个带有ItemRenderer和ItemEditor的数据网格。点击，因为我的数据网格是可编辑的，我可以修改编辑单元格的值。但是，当我使用tab键验证这些更改时，例如，itemrender值与开头时相同，不会出现任何更改。

你能解释一下如何解决这个问题吗？

<mx:DataGridColumn dataField="scRub2" headerText="{sNomCol2}" 
editable="true" width="{iNomCol2}"id="dgc1" wordWrap="true"
                                                                itemRenderer="itemRenderer.MultilineHTMLRenderer"
itemEditor="itemRenderer.irHtmlText"
editorDataField="htmlModif"

// itemEditor

<?xml version="1.0" encoding="utf-8"?>

<fx:Script>
    <![CDATA[

        public var htmlModif:String;
        protected function lblData_changeHandler(event:Event):void
        {
            htmlModif = lblData.htmlText;
        }
    ]]>

我没有运行您的代码，但认为将字段 htmlModif 更改为获取功能将解决您的问题

public var htmlModif:String;
        protected function lblData_changeHandler(event:Event):void
        {
            htmlModif = lblData.htmlText;
        }

到

    public function get htmlModif():String
    {
        return lblData.htmlText;
    }
