    you can write a if condition to check key code.

     

    //I dont know keycode is 38 or something

    if(event.keyCode.toString()=='38' || event.keyCode==Keyboard.UP)

    {

    //your business logic

    //launchSearchGrid();

    }

     

    Try this

                protected function datagrid1_keyUpHandler(event:KeyboardEvent):void
                {

    if(event.keyCode==Keyboard.DOWN || event.keyCode==Keyboard.UP)

    {


                    Alert.show("index :"+event.target.selectedIndex+"\n"+"Description :"+event.target.selectedItem.des);

    }

     

    }
