flex4.5 DataGrid 列中添加Button,事件函数中获取外部的方法、属性。

外部的方法和属性必须用public，内部列函数用
outerDocument 获得。

看例子吧:

//更新

public function updateData():void { _service = new RemotingConnection(_gatewayURL); _service.call("RemotingService.PlanConfiguration.deletePlanConfigurationData", new Responder(onUpdateDataResult,onFault),dgResult.selectedItem.id); }

//删除 public function delectData():void { _service = new RemotingConnection(_gatewayURL); _service.call("RemotingService.PlanConfiguration.deletePlanConfigurationData", new Responder(onDeleteDataResult,onFault), dgResult.selectedItem.id); }

1<s:DataGrid id="dgResult" width="100%" height="100%" dataProvider="{arr}">

2 <s:columns>
3 <s:ArrayList>
4 <s:GridColumn headerText="方案编号" dataField="id" width="65"/>
5 <s:GridColumn headerText="方案名称" dataField="name" width="65"/>
6 <s:GridColumn headerText="方案类型" dataField="type" width="65"/>
7 <s:GridColumn headerText="标题" dataField="tittle" width="38"/>
8 <s:GridColumn headerText="时间" dataField="date" width="70"/>
9 <s:GridColumn headerText="地点" dataField="site" width="38"/>
