Identify that the page is displayed due to the back button click of the browser

Posted Date Unknown Lovely Manuel 8 Comments

I have two pages in my website that uses a common master page. Page1 is the start up page and contains a link to Page 2. When I am in Page 2, I want to go back to Page 1 by clicking the 'Back' button of the Browser.Then I need to refresh/reload Page 1.

Please help with a sample code. Note that these pages are using a common master page.

I belive The method is to use a web user control and reuse it in as many pages as you need it by embedding it. You can show or hide each user controls embedded in pages( or you can load it in a place holder). If you tried to implement it in a web page, tracking each page contents might be tough when you hit back button (although not impossible and can be done using session object).

use this , it will work fine for all case

protected override void OnPreRender(EventArgs e)

{

base.OnPreRender(e);

StringBuilder javaScript = new StringBuilder();

javaScript.Append(" <script language=JavaScript> ");

javaScript.Append("window.history.forward(1); ");

javaScript.Append("</script> ");

Page.RegisterClientScriptBlock("HistoryScript", javaScript.ToString());

}

Also you can disable the caching of data and it is able to track the back button press, also able to hide the back button

code example

HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);

HttpContext.Current.Response.Cache.SetNoServerCaching();

HttpContext.Current.Response.Cache.SetNoStore();

Session.Abandon();

window.history.forward(1);

document.attachEvent("onkeydown", my_onkeydown_handler);

function my_onkeydown_handler()

{

switch (event.keyCode)

{

case 116 : // F5;

event.returnValue = false;

event.keyCode = 0;

window.status = "We have disabled F5";

break;

}

</script>

this will solve the issue

I think Johnson's answer is right and I was referring to another to another scenario (as I mis understood your question) .

My commend is for this scenario

Is it possible to put a Back and next button on the web page which remembers the values when the page moves forward or backward using the web page buttons without using session variables?.

Actually I don't want to disable or hide the Back button, I want the Back button enabled. But need to reload/refresh the coming page. I got many samples and are working fine for pages without master page. But I am using master page.

Why can you try to see HTML page source when the page is rendered on the Browser with the master page and then adjust the code so that it behaves correctly. Right now it might be overlapping with some other code..

All reload revents should write on master page page load event or prerender event
