back button of browser compitible with asp.net application

**Frinavale** · Mar 19 '09, 03:01 PM

I thought you said that you were using the browser's back button?
That you didn't have a button on your page named "back"....?

Either way, this is just proving that there are 2 pages stored in the browser's history...

In regards to the unrecognised tag.....what .NET Framework is your application being developed for?

Please post your asp code.

The ScriptManager class is part of the System.Web.UI namespace. It belongs to the System.Web.Exte nsions assembly (in System.Web.Exte nsions.dll). Make sure that this assembly is registered in your web.config file.

In your web.config, in the <assemblies> section you should have the following entries:

Code:

<assemblies>
    <add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=...."/>
    <add assembly="System.Web.Extensions.Design, Version=3.5.0.0, Culture=neutral, PublicKeyToken=...."/>
</assemblies>

no .. in our application does not have above assembly.. how to add this assembly in my application ... and wat about the public key..? and after adding this assembly ..error remains same....

**Frinavale** · Mar 19 '09, 04:25 PM

Create a new web application....
Try adding an UpdatePanel to the page.
If it works properly, go to the web.config and merge the <assemblies> section in with your application.

I hope that you are aware of the nature of the UpdatePanel.... anything within an UpdatePanel will perform a partial page update (an Ajax call).

Since this is the case, any JavaScript that is used by the controls within the UpdatePanel has to be registered with the ScriptManager.

The ScriptManager is responsible for managing all JavaScript/Ajax and StyleSheet resources used by the controls that participate in partial page updates (Ajax calls).

but in same application i added a page without inherited master page .. then i linked this page to login page... after click on link .. i navigated on new blank page... here the back button working fine... i.e. navigate on previous page on single click... ......?

**Frinavale** · Mar 19 '09, 04:57 PM

Ok, for now, forget I mentioned the UpdatePanel.
It sounds like something else is going on here.

At one time you said that when you hit the back button you are brought to the "MasterPage"... .

Could you please elaborate on this because I do not know what you're talking about here...

**avinash sh** · Mar 19 '09, 05:07 PM

as u asked ... IN start browser back button is looking enabled. and browser forword button is looking disabled ..if i click on browser back button ..page remains same but browser forword gets enable... and again click on browser back button then page is redirected on previous page....

do u suggest me or provide some code.. so that i can navigate back to previous two pages on click of browser back button only for my application.??? ? it should change this property only for my application ....

**Frinavale** · Mar 19 '09, 06:53 PM

So, your first page is the Login page....
The next page is some content page...

In your Login page, MasterPage, or Content page, do you have a Redirect happening?

If so, please post any methods that contain a redirect.

**avinash sh** · Mar 20 '09, 06:26 AM

no .. i am talking about browser back button functionality.. i d'nt want to use any other back button... plz tell me how to use browser back button useful in single click... in my application ..it is being in double click.....

I'm getting same issue:

Using master pages and Ajax. I have back button in app and when using history.back() the page stays on the same page, but when using history.go(-2) it goes back to previous page.

The browser back button has the same effect...if I click the browser back button then it stays on the same page, but if I double click the browser back button it moves to the previous page. The pages are visible in the browser history and selecting the previous page in the history takes you to the previous page correctly.

This is ONLY experienced in IE, Firefox works fine!

So there's a workaround for the application navigation, but this does not sort out the root of the problem.

**andrewr** · Jul 22 '09, 09:15 AM

I've found my problem. We using Response.Write( <script language='javas cript'> window.location ='" + URL + "';</script>) to redirect in order to set the statuscode (200) and description (OK). If we use response.redire ct then the browser back button works on single click (or history.go(-1)).

The javascript redirect does not show in the browser history, but will cause the first "back" to re-run the javascript leaving you on the same page. Firefox obviously handles this intelligently and ignores the javascript redirect.
