其实就和平时给列附值一样

mx:DataGrid x="0" y="0" id="myDG" dataProvider="{_AppData}"  width="100%" height="100%" itemClick="datagrid1_itemClickHandler(event)">
					<mx:columns>
						<mx:DataGridColumn headerText="河段" dataField="sHeDuan" />
						<mx:DataGridColumn headerText="目标" dataField="sMuBiao" />
						
						<mx:DataGridColumn headerText="现状" width="260">
							<mx:itemRenderer>
								<mx:Component>
									<mx:HBox paddingTop="6" horizontalScrollPolicy="off" verticalScrollPolicy="off">
									<mx:Image source="images/{data.sXIanZhuangImg}">
									</mx:Image>
									</mx:HBox>
								</mx:Component>
							</mx:itemRenderer>
						</mx:DataGridColumn>
						
						<mx:DataGridColumn headerText="达标">
						<mx:itemRenderer>
							<mx:Component>
								<mx:HBox horizontalAlign="center" paddingTop="6" horizontalScrollPolicy="off" verticalScrollPolicy="off">
									<mx:Image source="images/{data.sDaBiaoImg}">
									</mx:Image>
								</mx:HBox>
							</mx:Component>
						</mx:itemRenderer>
						</mx:DataGridColumn>
						
						<mx:DataGridColumn headerText="主达标项" width="130" dataField="sZHaoBiaoXiang"/>
						<mx:DataGridColumn headerText="图表" dataField="sMuBiao" width="80">
							<mx:itemRenderer>
								<mx:Component>
									<mx:HBox horizontalAlign="center" horizontalScrollPolicy="off" verticalScrollPolicy="off">
									<mx:Button useHandCursor="true" buttonMode="true" click="button1_clickHandler(event)" upSkin="@Embed(source='../images/chart_line.png')" overSkin="@Embed(source='../images/chart_line.png')" downSkin="@Embed(source='../images/chart_line.png')">
										<mx:Script>
											<![CDATA[
												protected function button1_clickHandler(event:MouseEvent):void
												{
													//trace(outerDocument.myDG.selectedItem.sId);
													//弹出对话框
													outerDocument.btnClick_Fun();
												}
											]]>
										</mx:Script>
									</mx:Button>
									</mx:HBox>
								</mx:Component>
							</mx:itemRenderer>
						</mx:DataGridColumn>
						
						
						
					</mx:columns>
				</mx:DataGrid>

我一般这么用：

import mx.collections.ArrayCollection;
import mx.controls.ComboBox;
import mx.events.FlexEvent;

public class ComboBoxItemRender extends ComboBox
{
private var _data:Object;
public function ComboBoxItemRender()
{
super();
this.width = 100;
this.addEventListener(FlexEvent.VALUE_COMMIT,valueCommitHandler);
}

override public function get data():Object
{
return _data;
}

override public function set data(value:Object):void
{
this._data = value;
}

private function valueCommitHandler(event:FlexEvent):void{

}
}

然后在设置 itemRenderer="包名.ComboBoxItemRender"
