If the user makes an Ajax callback and there is no internet connection, the Ajax failed event will fire after the Ajax callback times out. It can take quite a few seconds before the Ajax callback times out. It would be preferable to let the user know that Ajax callbacks are not possible before they try to make a callback. Also, in disconnected mobile applications, you might want to prevent the user from tying to synchronize data if the connection is poor.

In this video we show how this can be done.
