Notification - Outlook Mail

Isolate this demo as a stand-alone application
  • About this demo
  • C#
  • VB

The RadNotification in this demo is configured to make a callback to the server at every 3000 milliseconds. It checks whether there is a new message and if so—exposes the data to the client and pops up. If there is no new message, nothing happens (just a silent check in the background). Checking with a callback provides better performance compared to using AJAX in this scenario.
