title: How to display a waiting image on page load in asp net
body: <p>I want to show a waiting image/progress bar on page load event. In page load event, some code is being processed for displaying a report which takes 1/2 minutes to display on the aspx page, meanwhile the aspx is being empty and nothing is displyed, this is not so userfriendly. So, I want to show an image indicating page is being processed. 
  I tried searching in google and found some code samples but couldnt achieve my target. How to implement this. 
  Requirement is nothing but: Display an image/progress bar until the report is processed.</p>
  
  <p>Any help in this :) Thanks in advance.</p>
