1.假如ArrayCollection如下

var arrDataList:ArrayCollection=new ArrayCollection();
var item:Object=new Object();
item.BANK_ABSTRACT="银行对账单余额";
item.BANK_POSTINGDATE="";
item.BANK_DOCNUM="";
item.BANK_MONEY=bankBalance;
item.BANK_REASON="";
item.COMPANY_ABSTRACT="公司银行存款账面余额";
item.COMPANY_POSTINGDATE="";
item.COMPANY_DOCNUM="";
item.COMPANY_MONEY=bookBalance;
item.COMPANY_REASON="";

2.DataGrid定义如下：

<mx:AdvancedDataGrid id="datagrid" width="100%" height="200" dataProvider="{arrDataList}"
                verticalScrollPolicy="auto" editable="true" itemEditEnd="onItemEditEnd(event)">
                <mx:groupedColumns>
                    <mx:AdvancedDataGridColumnGroup headerText="银行">
                        <mx:AdvancedDataGridColumn headerText="摘要" dataField="BANK_ABSTRACT">
                            <!--
                            <mx:itemRenderer>
                                <mx:Component>
                                    <mx:Label>
                                    <mx:Script>
                                        <![CDATA[
                                            override public function set data(value:Object):void
                                            {
                                                super.data=value;
                                                if(value.BANK_ABSTRACT=="+")
                                                {
                                                    this.text="加：企收银未收";
                                                }
                                                else{
                                                    this.text="减：企付银未付";
                                                }
                                            }
                                        ]]>
                                    </mx:Script>
                                    </mx:Label>
                                </mx:Component>
                            </mx:itemRenderer>
                            -->
                        </mx:AdvancedDataGridColumn>
                        <mx:AdvancedDataGridColumn headerText="入账日期" dataField="BANK_POSTINGDATE"/>
                        <mx:AdvancedDataGridColumn headerText="原始单据号码" dataField="BANK_DOCNUM"/>
                        <mx:AdvancedDataGridColumn headerText="金额（元）" dataField="BANK_MONEY"/>
                        <mx:AdvancedDataGridColumn headerText="未达原因" dataField="BANK_REASON"/>
                    </mx:AdvancedDataGridColumnGroup>
                    <mx:AdvancedDataGridColumnGroup headerText="公司">
                        <mx:AdvancedDataGridColumn headerText="摘要" dataField="COMPANY_ABSTRACT"/>
                        <mx:AdvancedDataGridColumn headerText="入账日期" dataField="COMPANY_POSTINGDATE"/>
                        <mx:AdvancedDataGridColumn headerText="原始单据号码" dataField="COMPANY_DOCNUM"/>
                        <mx:AdvancedDataGridColumn headerText="金额（元）" dataField="COMPANY_MONEY"/>
                        <mx:AdvancedDataGridColumn headerText="未达原因" dataField="COMPANY_REASON"/>
                    </mx:AdvancedDataGridColumnGroup>
                    <mx:AdvancedDataGridColumn headerText="操作"/>
                </mx:groupedColumns>
            </mx:AdvancedDataGrid>

3.DataGrid单元格编辑后需要获取新值，并把新值更新到ArrayCollection中，那么，DataGrid单元格编辑完成后事件方法如下：

private function onItemEditEnd(event:AdvancedDataGridEvent):void{
                 var col:AdvancedDataGridColumn=datagrid.columns[event.columnIndex];
                var newValue:String=datagrid.itemEditorInstance[col.editorDataField];
                var dsFieldName:String=event.dataField;
                arrDataList.getItemAt(event.rowIndex)[dsFieldName]=newValue;
             }
