Disable back button in browser

[pallavi kondapure]

Hi All,

 

I have a web page ,basically content page that is using AJAX controls(in .Net 3.5) ,Now my requirement is to disable back button in the browser .I have put

window.history.forward();

I am calling this code on onload  in javascript

window .onload

 

This  code works the first time the page is loaded.but when i click submit button a gridview is shown in the same page ,then when I click on the Back Button of the browser the following message appears

 

"Warning: Page has Expired "

 

I want to show the same page when the user clicks the browser Back button.

Kindly Suggest

 

Thanks in advance

Browser "Back Button" is not meant to go forward.......

I am trying to fully understand. I am guessing that when you click
submit that you are wanting it to update something, and continue
to "show the same page" ... i.e. the submit button is really there
to trigger the update through AJAX?

If you are sending the update through AJAX to like a handler (.ashx)
or something ... try changing the submit button to just an
ordinary button with a javascript function that triggers the AJAX.

Or, may have to give a few more details on exactly what you are
trying to do on the page ...
1. what it looks like when it loads
2. what you are wanting to do when button clicked (and is that
going through Ajax)
3. what do you want the page to look like after the button click ...
just like it did on load?

Good luck :)

P.S. All code, information, and/ or advice is for entertainment

Yeah, the best solution is don't try and disable the back button. It is defined behaviour which shouldn't be tampered with.

Method 1) Client Side Javascript

========================

<script type = "text/javascript" >
function disableBackButton()
{
window.history.forward();
}
setTimeout("disableBackButton()", 0);
</script>

 

call disableBackButton() onload of the page

 

Method 2) Codebehind

=================

Override OnPreRender and register the above script

 

Method 3) Disabling browser caching

===========================

By disabling browser caching or cache either in Page_load event or in Page_Init event
