title: Show reminder as floating popup/alert
body: <p>I need to show a reminder as floating popup/alert in my asp.net mvc (C#) application.</p>
  
  <p>When the user has any information from the admin that should be notified at particular time, i need to show it as floating popup/alert in the user's screen.</p>
  
  <p>For ex.: When the admin sets an alert "Payment due last date is 15-Oct-2009" to notify the user on "12-Oct-2009 10:00 AM". Then it should show the alert to the user on "12-Oct-2009 10:00 AM" as "Payment due last date is 15-Oct-2009".</p>
  
  <p>Is there any simple way to do this?</p>
