a labelfunction will do the calculations as you tab through the fields
or as change rows on the grid.
I use this to do some calculations and it works great.
private function calcAdjAmount(item:Object,column:DataGridColumn):String {
var adjustedAmt:Number;
var emptyField:String = "";
if (item['Num_Cases_Claimed'] != null) {
adjustedAmt = item['Num_Cases_Claimed'] *
Number(removeFormatting.format(item['Net_Promo_Amt']));
return
basicCurrencyFormat.format(adjustedAmt.toString());
}
else {
return emptyField;
}
}
