dynamic update data

Hi guys,

I am developing pizza ordering application. I have two forms:

1) For inserting new pizza

2) and for ordering.

Here you can see:

When I insert a new pizza and go to check on combo box (picture ordering) I can't see my new pizza in combo box. The new pizza is inserted in my databases. The pizzas in combo box are from my database.

I have one idea.  But I don't think it is good. To use

    Timer t = new Timer() {        public void run() {          //display all pizza from my database every 2 se to combobox        }      };

t.schedule(2000);

Any idea for better approach???

Thanks
