一部の列が編集可能なデータグリッドがあります。available_quantity、sales_quantity、return_quantity の 3 つの列があり、そのうち sales_quantity と return_quantity は編集可能です。私が欲しいのは、ユーザーが sales_quantity と return_quantity を入力すると、合計が available_quantity よりも大きい場合、すぐにアラートが表示されるはずです。これを処理するためにkeyupイベントを書きました..

protected function dataGrid_keyUpHandler(event:KeyboardEvent):void
        {
            // TODO Auto-generated method stub
            var avail_qty:int=parseInt(dataGrid.selectedItem.available_qty);
            var return_qty:int=parseInt(dataGrid.selectedItem.return_qty);
            var sales_qty:int=parseInt(dataGrid.selectedItem.sales_qty);
            var total:int=return_qty + sales_qty;
            if(total>avail_qty)
             Alert.show("hi");
        }

but the problem is first time when i edit the value sales_quantity and return_quantity it does not show me alert even there total is greater than available_quantity. If i click any one of the column again and press backspace then it shows me "hi" in alert. which event should b used to handle this. Keypressed event is not available in datagrid

私はこのイベント「itemEditEnd」を聞きます:)
