Here's another way:
<mx:DataGrid id="mygrid" dataProvider="{initDG}" >
<mx:columns>
<mx:DataGridColumn id="grant_year" dataField="grant_year"/>
<mx:DataGridColumn id="cashoutshares" dataField="cashoutshares">
<mx:itemRenderer>
<mx:Component>
<mx:Canvas>
<mx:Script>
<![CDATA[
override public function set
data(value:Object):void
{
super.data = value;
if (value != null)
{
myCheckBox.selected =
data.cashoutshares;
myCheckBox.visible =
data.grant_year == '1995' ? true : false; // your logic
super.invalidateDisplayList();
}
]]>
</mx:Script>
<mx:CheckBox id="myCheckBox"
click="data.cashoutshares=myCheckBox.selected"/>
</mx:Canvas>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
</mx:columns>
</mx:DataGrid>
This works because the data property in an itemRenderer contains all of
the fields for a row in a dataGrid's dataProvider.
