Maybe:
override public function set data(value:Object):void
{
if(value != null)
{
super.data = value;
selected = ( value.label == "true" ? true: false);
}

Subject: [flexcoders] Re: Center Checkbox in DG Column
I dont know what I am missing, but still not working for me.
Here is my code:
import flash.events.Event;
import mx.controls.*;
import mx.controls.dataGridClasses.DataGridColumn;
import mx.controls.listClasses.IDropInListItemRenderer;
public class checkBoxGrid extends CheckBox implements
IDropInListItemRenderer
{
public function checkBoxGrid()
{
super();
addEventListener("change", onClick);
}
override public function set data(value:Object):void
{
if(value != null)
{
super.data = value;
selected = value.label;
}
}
//called by click of the checkbox
private function onClick(e:Event):void
{
var dataFieldName:String = DataGrid
(listData.owner).columns[listData.columnIndex].dataField;
data[dataFieldName] = String
(selected); //set the checkbox state into the dataProvider
}
}
mxml implementation:
<mx:DataGridColumn headerText="Include into Report"
dataField="includeintoreport" width="40"
textAlign="center">
<mx:itemRenderer>
<mx:Component>
<modulecode:checkBoxGrid/>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
Data sample: Fragment
vendors>
<ccompany>
A. FEIBUSCH CORP.
</ccompany>
<includeintoreport>
false
</includeintoreport>
<cvendno>
ZIPPER
</cvendno>
</vendors>
When I run it all chckboxes come checked despite false in
includeintoreport field. So, when I click on a checkbox nothing is
changed, it keeps checked status.
Hope, someone can help.
