PageRequestManagerServerErrorException 12019 12130 12031 and 12152

Any ideas what causes the following error message:

Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code is:

I receive one of 4 error numbers: 12019 12130 12031 or 12152

I believe it might have to do with a content switch but not sure. Any help would be greatly appreciated.

I am getting the same Error Message with error number :12031...

Any suggestion ?

Hi,

Please refer to this:http://support.microsoft.com/kb/193625

The issue seems to be with the WinInet api, may be you can try to access it with another browser to see if it works.

Hi,

it is true that it is about Wininet api.i can access my page and can work with Another browsers but with IE 7.0 OR 6.0 i come accross with this error.(in I.E The error code is 404)..What is ur advice to solve this problem?When i launch the project without connecting to source safe,it works but after i connect to sourcesafe,this problem occurs..This error is very annoying.What should i do?Thank u very much for ur Help.(My problem doesnt depend on Data Intesivity or row count)

Hi, Please refer to this:http://support.microsoft.com/kb/193625

The issue seems to be with the WinInet api, may be you can try to access it with another browser to see if it works.

So, seeing this error on a partial-page update (UpdatePanel Async postback) means that the application I'm developing is not going to work with Internet Explorer? Or is this just a fluke that will go away on a restart / deployment scenario / etc.

I'm getting this one:

 12019 ERROR_INTERNET_INCORRECT_HANDLE_STATE
 The requested operation cannot be carried out because the handle supplied is not in the correct state.

Hi

we had the same problem on our live-system. It was caused by SSL-Connection. If you have SSL, try turning off Keep Alive for IE.

hth

Just so you know, we did find one possible cause of this problem.

It seems to crop up sometimes if you are using IE6 supplied with MultipleIEs package.

PageRequestManagerServerErrorException, status code 504

I got the following error message on my ASP.NET AJAX web app:

Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 504

What does it mean?

Hi monkeyno,

10.5.5 504 Gateway Timeout

The server, while acting as a gateway or proxy, did not receive a timely response from the upstream server specified by the URI (e.g. HTTP, FTP, LDAP) or some other auxiliary server (e.g. DNS) it needed to access in attempting to complete the request.

 Note: Note to implementors: some deployed proxies are known to return 400 or 500 when DNS lookups time out.

To troubleshoot this issue, we really need the source code to reproduce the problem, so that we can investigate the issue in house. It is not necessary that you send out the complete source of your project. We just need a simplest sample to reproduce the problem. You can remove any confidential information or business logic from it.

You get the Sys.WebForms.PageRequestManagerServerErrorException whenever the aspx handler throws an exception responding to an ajax.net update panel submit. If you took away the update panels you would see the classic asp.net exception page with lots of potentially useful information like the stack trace, but since the form submit has been ajaxified you just get a generic error message through a javascript alert. For example create an aspx page with an update panel containing a button and a multiline text control with the text set to "".

monkeyno:

Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server.

Clicking on the button you'll get the generic error: The status code returned from the server was: 500 Now try it again after placing the controls outside of the update panel. When you click the button you will get an exception page with details about a potentially dangerous/script-attack form value. The exception evens details a possible (though non-recommended) workaround of adding the attribute, ValidateRequest="false", to the aspx page directive. Of course for a real page it's a pain to strip out the update panels, so here is a quicker way to see the exception details. Just add the attribute, EnablePartialRendering="false", to your ScriptManager like below. Just set it back when you're done troubleshooting the issue.

Nobody? Do I need to give some additional info? This problem really holds up my development so please help meout here.

hello.

well, i guess that you must see if ASP.NET 2.0 is installed in IIS and if the vdir you've created there is configured to use it...

ASP .Net 2.0 is installed and the site also uses the 2.0 version. The error is about ATLAS so I think I have a configuration problem there? I use windows 2003 server.

Hello,

Parser Error Message: Could not load file or assembly AjaxControlToolkit or one of its dep

Hi,

I am using ASP.Net 2.0 with AJAX Extensions 1.0. And one of my aspx was using 2 of the ajaxtoolkit namely the ModalPopupExtender and RoundedCornersExtender. But why is it that when I will access the page from the web server the error below will display on the page. It's really frustrating because there's no problem when running locally in my machine thru Visual Web Developer 2005 Express Edition.

I hope you could help me figuring the problem.

Thanks

You need to deploy the AjaxControlTookit (DLL) to the server (in your bin directory or in the GAC).

-Damien

Hi hifiger2004,

You can just include the AjaxControlToolkit.dll into the BIN folder of your website/webapplication. There is no need to deploy it to the GAC. (Maybe you don't have the right to do that.)

Also check if some plain ajax functionallity works on the webserver!!! For example: A simple updatePanel holding a datetime.now, and a button to trigger it. Note that the ajax functionality must work in order to use the AjaxControl Toolkit.

Please let me know how it worked out!
Kind regards,
Wim

You have to include the AjaxControlToolkit.dll into the bin folder of your webapplication

Parser Error Message: The entry ScriptModule has already been added.

On my development system everything is running fine, when i publish to my beta server (SBS 2003 - *no* VS installed) I get the following error:

Parser Error Message: The entry 'ScriptModule' has already been added.

Removing this line resolves the issue but then presents me with various errors relating to not being able to load System.Web.Extensions... If i can understand why the first issue is occuring this would help! Any clues?

Hi,

I have exactly the same happening on my server, does anyone have a fix for this ?

Thanks
James

This can happen if there are two HttpModules named "ScriptModule". This can mysteriously happen if you are running a virtual directory under an asp application that already has the module defined. You can either remove the HttpModule declaration<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> from the VD web.config, or all a remove node

<remove name="ScriptModule" />

just before adding it back.

Hi,

Excellent, thanks for the heads up.

James

That was an excellent post. Thank you for your help !

This suggest is not working for me again and again the same error only i am getting is there any other solution

please let me know soon......

Parser Error Message: Type System.Web.UI.UpdatePanel does not have a public property named

Hi, first post...I am fairly new to ajax and was looking for some guidance on my problem. I installed the 3 files (Ajax 1.0 RC, Toolkit and the Futures December CTP). I wanted to convert an exsisting and working .net 2.0 sample aspx page into AJAX to learn how the updatepanels work. The page contains a bunch of datagrids that i wanted to place inside "updatepanels".

However, I keep getting the parser error"Type 'System.Web.UI.UpdatePanel' does not have a public property named 'datagrid'." whenever I placeanything inside the panels (table, div, tr...etc). I am sure its a pretty straight forward problem but not sure where to start looking.

If it matters, my solution in MS Visual Studio does not include a BIN folder. (something tells me i need it) I created a "New Website" and selected "AJAX-enabled website" and went from there. I could not find templates to start working from.

Thanks in advance!
Skimo!

you cant load datagrid in the page.load when its inside of UpdatePanel.

This is because UpdatePanel gets call first before the grid gets load. Thats is why it couldnt find it.

you can have button inside of updatepanel, when you click the button the it will do databind with grid

It is indeed a straightforward problem. Everything inside an UpdatePanel goes inside a "ContentTemplate", like this:

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:DataGrid ...>
</asp:DataGrid>
</ContentTemplate>
</asp:UpdatePanel>

Thank you so much!! I learned something :)

Does this mean I do not need to worry about the BIN folder not being there?

-Skimo

You won't need a bin folder to just use ASP.NET AJAX itself, since it gets installed globally for the machine.

If you use the AJAX Control Toolkit or the December Futures CTP, then your project will need to have the appropriate binaries in the bin folder.

I'm glad you're off and running... good luck exploring ASP.NET AJAX!

Great thanks for your help!
