I am executing a SSRS 2008 report from report manager so it opens in a web browser. Since it is a big report it takes some time for execution. During this time i get an error icon on the left bottom of the web browser and the execution stops. When I click open the error icon to see the details it says,
"Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12029."
The other relatively smaller reports are coming up successfully without any issue.

I'm loading a .aspx page via fancybox (ajax loading mode).I was using fancybox 1.2.6, working fine, then upgraded to fancybox 1.3.4 and IE now triggers the JS error above (in the subject of the post). Then why am I posting on ASP.net forum you might ask?!?... read on...Debugging the JS code, the error happens inside jQuery in the .html(data) function where it does a evalScript .each scripts inside data. jQuery version is 1.4.2.I'm able to resolve the problem by editing fancybox-1.3.4.js at line 265. I just use innerHTML to circuvent the evalScript that occurs inside html()... and it works:
//tmp.html( data ); <-- original code commented out where JS error occured
var tmpDiv = tmp.get(0); <-- new "plaster" kind-of fix
tmpDiv.innerHTML = data; <-- new "plaster" kind-of fix
Why I'm posting on ASP.net and not on jQuery nor fancybox groups is that I consider that the proper fix would be in the .aspx that is loaded via ajax.To summarize the problem. There is a base .aspx page that has a couples of text and buttons. When you click a button, it loads via AJAX a new .aspx page (using fancybox). You end up with two ScriptManager js code and it triggers an error when executing :
//<![CDATA[
Sys.WebForms.PageRequestManager._initialize('ctl00$ScriptManager', document.getElementById('aspnetForm'));
Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [], 90);

I'm trying to use a DynamicPopulateExtender to add a product to the cart and then report back a success/failure-message to a div. After the request has finished, i'd also like to trigger an update of an UpdatePanel on the page. But there is a problem: To ensure that the div is visible only a short time after the request has finished, and to reload of the UpdatePanel, I need to know when the request has finished - and it seems that the DynamicPopulateControl for some reason doesn't trigger the PageRequestManager EndRequest-event. I've registered for the events with this code, and I've made sure that the code that registers the events run like it should. But neither CartBeginRequest nor CartEndRequest are ever called:
function pageLoad(sender, args){

How to remove all endRequest handlers in PageRequestManager?
View 1 RepliesWhen jQuery is applied to elements in an UpdatePanel, when the UpdatePanel refreshes, the jQuery is not applied to the newly injected HTML. This issue is resolved by using
Sys.WebForms.PageRequestManager.getInstance().add_endRequest() to register a function to be called when the AJAX request is complete: I've written a function that registers the function with add_endRequest, and also calls it at the same time:
Async.RegisterAndRun = function(callback) {
//register function to be run when an update panel request is complete
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(callback);
//also run the function right now.
callback();
};
Now all we need to call is Async.RegisterAndRun(AddFancyjQueryToMyHTML); or
Async.RegisterAndRun(function(){
AddFancyjQueryToMyHTML();
AddMoreFancyjQueryToMyHTML('with', 'args');
});
Currently it does what I need it to, and I never need to explicitly call add_endRequest which is nice.

My master page contains:
var requestMgr = Sys.WebForms.PageRequestManager.getInstance(); requestMgr.add_initializeRequest(InitializeRequest); requestMgr.add_endRequest(EndRequest); which present an ajax indicator whenever page make a ajax call.One of the page have a button, when click this button simple do Response.Redirect and no any ajax call.Here is the problem: It works fine in local machine.But when multiple users visit the application via Citrix for a while, when they clieck this button, some users immediate got PagerequestManagerTimeoutException error.To solve this problem, they have to keep click this button or restart their PC ,It also solve the problem if we restart the Citrix.I already set AsyncPostBackTimeout="360000" and <httpRuntime maxRequestLength="1024000" executionTimeout="999999" />
I have an ASP.Net AJAX website we've developed which works fine when its working in the root of a IIS7 website. When it was deployed however the client has requested it be installed as an application under a pre-existing website.Currentlt that website is the Default Web Site on 80. Now the application isn't in the root of the website it is throwing these 405 errors to the browser. The root website is running as network service and the app itself is running in a different app-pool with a service account.

I've figured out that it's something to do with the ScriptManager. I can get a responce from the ScriptResource.axd when it's in the root of a site as soon as I move it to a sub application it starts throwing errors. Here is the relevent output from the
IIS Logs. As you can see, all the calls to ScriptResource.axd end up as 401.2 errors.

I am using the asp.net with c# and using the update panel, i am getting the error sometime not all time and no page navigate after then,its occure only in mozilla fire fox.

I am getting this error when there is a Asynpostback. following is the markup
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="StepTwo.aspx.cs" Inherits="PAN.UI.StepTwo"
Whenever a postback would occur (AJAX'ed by an UpdatePanel) I want to do a callback beforehand and only after the callback has completed (either successfully or not) should the postback occur. How can I do this?
Elaborate explanation: We use ASP.NET AJAX (UpdatePanel 'n stuff) together with DevExpress controls. Among those controls is the ubiquitous GridView. As is typical with ASP.NET gridviews, you can edit rows one-by-one, and to save your changes you have to hit the "update" button at the end of the row. However if you make some changes to the row, then forget to press the "update" button, and hit something else in the page (say the big red SAVE button that causes a postback and saves the whole form to the DB), your changes will be lost. The row will still be in edit mode, but it will have reset to the data it had initially when you started the edit.
Our clients are not happy with this and want the row to be saved automatically if the user forgets to do so himself. Luckily the DevExpress gridview is smart enough to have an "Update()" method which I can call from JavaScript. Unluckily that causes a callback and returns immediately. If I allow the postback to continue as normally, the callback will get aborted. Well, technically it's a race condition I guess, but so far it seems that the postback wins. There are events to which I could attach for success/failure of the callback, but I don't know how to "resume" the postback that started it all. We could turn off callbacks for all the grids, but that would be a performance disaster.
