C#

Hi to all..

I am trying to develop a desktop application for a small restaurant. This consist of two applications, one for the cashier or front and the other is for the kitchen.

Here's the scenario:

If the customer comes and give their orders based on the menu, the Cashier will input their order to the application or system and it will automatically be displayed in Kitchen Application.

My problem is that, I want to make a warning or blinking thing in my Kitchen display application (i am using the datagridview for the displaying of orders or menus) so that the ones who is monitoring the newly ordered menus can easily know that there are new orders?

I hope you can help me through this because I am only a novice for this kind of development.

Thank you all.. God bless..
