Ol=E1 F=E1bio, tudo bem?


No Flex 2.0 n=F3s temos os itemRenderers e os itemEditors. O primeiro
apenas apresenta a informa=E7=E3o e o segundo permite mud=E1-la. Pelas
informa=E7=F5es que voc=EA sugeriu suponho que voc=EA esteja querendo usar =
um
itemRenderer como itemEditor. Neste caso algumas "regras" devem ser
seguidas:

1=2E O seu dataGrid deve ter a propriedade editable=3Dtrue
2=2E A sua coluna que tem o combo deve ter a propriedade
rendererIsEditor=3Dtrue
3=2E A sua coluna que tem o combo deve ter a propriedade editorDataField
definida
4=2E O seu itemRenderer deve prover uma forma de configurar a
propriedade informada no editorDataField

Veja o exemplo:
<?xml version=3D"1.0" encoding=3D"utf-8"?>
<mx:Application xmlns:mx=3D"http://www.adobe.com/2006/mxml"
layout=3D"vertical">

	<mx:Array id=3D"col3Data">
		<mx:String>col1.3.1</mx:String>
		<mx:String>col1.3.2</mx:String>
		<mx:String>col1.3.3</mx:String>
	</mx:Array>

	<mx:DataGrid editable=3D"true">

		<mx:dataProvider>
			<mx:Object col1=3D"col1.1" col2=3D"col1.2" col3=3D"{col3Data}"/>
			<mx:Object col1=3D"col2.1" col2=3D"col2.2" col3=3D"{col3Data}"/>
			<mx:Object col1=3D"col3.1" col2=3D"col3.2" col3=3D"{col3Data}"/>
			<mx:Object col1=3D"col4.1" col2=3D"col4.2" col3=3D"{col3Data}"/>
			<mx:Object col1=3D"col5.1" col2=3D"col5.2" col3=3D"{col3Data}"/>
			<mx:Object col1=3D"col6.1" col2=3D"col6.2" col3=3D"{col3Data}"/>
			<mx:Object col1=3D"col7.1" col2=3D"col7.2" col3=3D"{col3Data}"/>
			<mx:Object col1=3D"col8.1" col2=3D"col8.2" col3=3D"{col3Data}"/>
			<mx:Object col1=3D"col9.1" col2=3D"col9.2" col3=3D"{col3Data}"/>
			<mx:Object col1=3D"col10.1" col2=3D"col10.2" col3=3D"{col3Data}"/>
		</mx:dataProvider>

		<mx:columns>
			<mx:DataGridColumn dataField=3D"col1"/>
			<mx:DataGridColumn dataField=3D"col2"/>
			<mx:DataGridColumn dataField=3D"col3" rendererIsEditor=3D"true"
editorDataField=3D"selectedItem">
				<mx:itemRenderer>
					<mx:Component>
						<mx:Canvas>
							<mx:Script>
								<![CDATA[
									[Bindable]
									public var selectedItem:Object;
								]]>
							</mx:Script>
							<mx:ComboBox id=3D"cb" dataProvider=3D"{data.col3}"
								change=3D"selectedItem=3Dcb.selectedItem"/>
						</mx:Canvas>
					</mx:Component>
				</mx:itemRenderer>
			</mx:DataGridColumn>
		</mx:columns>

	</mx:DataGrid>

</mx:Application>


Espero ter ajudado!
