does page reload on back button?

[ramanaths]

Hi

I have a page that shows many thumbnail images. on load of this page i have some code that invokes a javascript which shows a message saying 'loading images'... this is hidden once all the page/images loads fully. when i navigate to some other page and then hit the back button of the browser the javascript fires and i get the 'loading images'. the images load fast (maybe from cache). but i was thinking i shouldn't be getting the 'loading images' message.

on going to a page by clicking the back button in the browser does the page reload all over again? i would think it should just go back and not do the reload. isn't that how it should work? is there a way i avoid page load (events)?

thnx.

Welcome to TSDN. Usual way is to use if not Page.IsPostBack :
If Not Page.IsPostBack

The page_load event will fire every time the page is sent to the server via a postback. If you want to show something the first time the page is accessed use the the !IsPostBack method as kenobewan mentioned. You can see this if you put a break point in your page_load event and do any of the following:

Click refresh.
Hit browser back button.
Do any type of postback event. (button click, etc..)
