我有一个带有 ItemRenderer 和 ItemEditor 的数据网格。单击时,由于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 值与开始时相同,没有出现任何更改。
你能告诉我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"
// 项目编辑器
<?xml version="1.0" encoding="utf-8"?>
<fx:Script>
<![CDATA[
public var htmlModif:String;
protected function lblData_changeHandler(event:Event):void
{
htmlModif = lblData.htmlText;
}
]]>
</fx:Script>
<mx:TextArea id="lblData" top="0" left="0" right="0" bottom="0"
htmlText="{dataGridListData.label}" preinitialize="initTA()"
change="lblData_changeHandler(event)">
<fx:Script>
<![CDATA[

override public function get listData():BaseListData

return _listData;

override public function set listData( value : BaseListData ) : void
{
_listData = value;
}
private function onChange(event:Event):void
{
this.data[ (listData as DataGridListData).dataField ] = lblData.htmlText;
}
public function initTA():void {
addEventListener("dataChange", handleDataChanged);
}
public function handleDataChanged(event:Event):void {
// Cast listData to DataGridListData.
var myListData:DataGridListData =
DataGridListData(listData);
// Access information about the data passed
// to the cell renderer.
trace("row index: " + String(myListData.rowIndex) +
" column index: " + String(myListData.columnIndex));
}

谢谢
