GridColumn and dataProvider update

Hello,

in a Spark GridColumn, how to detect if the DataGrid.dataProvider has been
updated ?

/<s:DataGrid id="dg" x="100" y="48" selectionMode="multipleRows"
requestedRowCount="4">
	<s:columns>
		<s:ArrayList>
			<s:GridColumn dataField="myBoolean">
				<s:itemRenderer>
					<fx:Component>
						<s:GridItemRenderer>
							<fx:Script>
								
							</fx:Script>
							<s:CheckBox id="cb" label="" horizontalCenter="0"
change="data.myBoolean=cb.selected;"/>
						</s:GridItemRenderer>
					</fx:Component>
				</s:itemRenderer>
			</s:GridColumn>
                <s:GridColumn dataField="dataField1" headerText="Column
1"></s:GridColumn>
                <s:GridColumn dataField="dataField2" headerText="Column
2"></s:GridColumn>
                <s:GridColumn dataField="dataField3" headerText="Column
3"></s:GridColumn>
		</s:ArrayList>
	</s:columns>
	<s:typicalItem>
		<fx:Object dataField1="Sample Data" dataField2="Sample Data"
dataField3="Sample Data"></fx:Object>
	</s:typicalItem>
	<s:ArrayCollection>
		<fx:Object dataField1="data1" dataField2="data1"
dataField3="data1"></fx:Object>
		<fx:Object dataField1="data2" dataField2="data2"
dataField3="data2"></fx:Object>
		<fx:Object dataField1="data3" dataField2="data3"
dataField3="data3"></fx:Object>
		<fx:Object dataField1="data4" dataField2="data4"
dataField3="data4"></fx:Object>
	</s:ArrayCollection>
</s:DataGrid>/

thanks

Hello,

You should be able to add a "collectionChange" event handler to your ArrayCollection.

https://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/mx/collections/ListCollectionView.html#event:collectionChange

For example:

--------------------------------------------------------------------------------------------------------------

<s:ArrayCollection collectionChange="collectionChangeHandler (event)">

--------------------------------------------------------------------------------------------------------------

private function collectionChangeHandler(event:CollectionEvent):void
{
	// See changes here. There will be a "kind" property in the event object to tell you which kind of change has occurred.
}

--------------------------------------------------------------------------------------------------------------
