I'm using IE 7 to run a simple test from page1 to page2 and back again wanting to see if the form data comes back on page1 for the controls.

I'm using VS 2008 and created an ASP.Net 3.5 Extensions Website. I'm storing the state in a HistoryPoint, but when I go back to page1, I don't even hit the breakpoint at the ScriptManager.Navigate event.

I have the UpdateMode set to Conditional on the UpdatePanel; a trigger set up for the ScriptManager control on the Navigate event; have EnableHistory set to True on the ScriptManager.

If I could send a zip file of this tiny project here, I would. But, I really need help with this one. I'm tearing my hair out on it. I've tried everything I can think of. I thought maybe it was my web.config file (not having the right extensions, etc), so I removed it and added a clean one.

Here is my web.config file:

Note that I'm only having a problem with the Navigate event. It is storing the state just fine. When I'm on page2 and click back, the Navigate event isn't hit.

If you need any more code in relation to this project, please let me know. I would appreciate knowing what's going on because I plan to use this concept in a business project at work. If I can't get the history to work, no use using AJAX.

Thanks so much in advance....

 How do you mean 'When I hit back', do you mean the back button in your webbrowser? I wasn't able to figure this one out because you didn't post your page2 source.
 

Yes... I meant hitting the Back button in my browser.

Page2 is really insignificant. It only consists of 3 textboxes which receive the querystring values from page1.

 I see, i thought i had a answer but i was wrong (never used the navigate event). But maybe this link can be of some help? :

 http://bytes.com/forum/thread775505.html
 

Thanks... At least someone responded. I'm so surprised that no Microsoft personnel has responded to this thread. It's a very simple problem, but with huge benefits (if it works).....

I sent an email to the person via the link you sent hoping he might be ble to respond to the link knowing what might be going on...

Does anybody have an explanation about this issue explained more in detail at the following link:

http://www.codeproject.com/KB/aspnet/ajaxhistorymanagement.aspx?msg=2514710#xx2514710xx

Hi, let me direct this to someone on our team who should be able to give some advice on this...

Thank you so much. I would really appreciate that...

If you need any other info, just let me know and I'll be glad to supply it. The way the History works now, it is just not going to "cut it" in a real world scenario.

That's because of the redirect. Why do you need to redirect?

If you're going to navigate away from the page, you don't need the Ajax history feature: you can just use the querystring to manage and restore state.

Hello. I also have strange browser history problem which can be reproduced under IE6/IE7.

You probably saw History control example: http://quickstarts.asp.net/Futures/ajax/doc/history.aspx.

 It works perfectly under IE and FireFox. But try this: copy first demo source code (http://quickstarts.asp.net/Futures/util/srcview.aspx?path=~/ajax/samples/history1.src) to newly created ASP.Net 3.5 Extensions Website. Run this example in Internet Explorer (I used IE 7.0). Click all three buttons ('1', '2', '3') with 1 second interval. Notice navigation history items, there are four of them: Current Page + three items for each button click. Now navigate to some other web site (type http://www.google.com for example in your address bar and hit enter). Look at navigation history once more, only two items are present, all  three records from our page collapsed to one which points to the last page's state. But this is not a problem. Click Back button. Collapsed record expanded back and now we have five history items. This is the behavior I expect

And now interesting part. Add to ButtonClick method next line of code

 ScriptManager.RegisterStartupScript(this, GetType(), "hmmm", "", true);  

Do all described steps from scratch. After you click Back button you'll see only two (not five) history items. Why??? What the magic is hidden inside ScriptManager.RegisterStartupScript()? It is the biggest problem with web history management inside IE which I cannot solve. I'll be very grateful for any help.

P.S. If modify web.config file and change <compilation debug="true"> to <compilation debug="false"> this will resolve described problem, but only described simple case. Such "fix" does not resolve this problem in web site which I am writing where AJAX controls extenders are present inside UpdatePanel .

I posted another comment at the following url which explains why this is happening:

http://www.codeproject.com/KB/aspnet/ajaxhistorymanagement.aspx?msg=2516760#xx2516760xx

Thanks for reply. But I still do not understand why FireFox maintain all History records after navigating to differ page and then back, and Internet Explorer forgets them. In fact I do not use MS History control, I use my own one which suffer from similar problem. Later I investigated that MS History control also has such a problem. I suppose the main reason of this 'bug' is that hidden IFRAME is used to maintain history under IE, so when we go away from our page all History Items which are owned by IFRAME disappears. They appear after I click Back and navigate to page with this hidden IFRAME - but they do not appear if ScriptManager.RegisterStartupScript() was called during SOME async postback. It is a mystery which I still do not comprehend
