If your CheckBox is an ItemRenderer, each instance will have access to the
data for the entire row. Depending on the scope of your var dsplValue and var
dataValue, you should easily be able to add a "change" event handler on the
checkbox that calls a function to set these values: inline example stub
<mx:DataGridColumn....>
<component>
<mx:CheckBox change="setVals()" selected="{data.CBColumnVar}">
<mx:Script>
<![CDATA[
private function setVals():void{
if ( this.selected ){
ModelLocator.getInstance().dsplValue = data.dsplValueColumnVar;
//or however you reference your VARs
