in javascript code to get ajax call by updatepanel. I got this code and it worked. Please guide and help me who this server side code (Sys namespace) was used on client side. Why not other namespaced are accessable in javascript ? That is that techniqueetc
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 using callout ajax control but i'm getting an error "sys.extended.UI.PositioningMode.Absolute"
View 2 RepliesI'm using a ScriptManager and including a webservice in the script generation. Upon calling the web service method via the javascript, I get the expected response except in IE 7/8. I get the error 'undefined' is null or not an object. I do not get this error in FireFox, Chrome and even Safari. The catch is, this is Microsoft's own generated code coming from the generated code from the script manager! This is the code that the error is thrown on:

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 am getting this error:
[Code]....
in my application for a module that displays detailed data in a tab control. I think I have determined the TabContainer1 is the name of the "This" element that is having the issue. I figured this out by debugging the ScriptResource.axd file. Here is the offending lines of code:
[Code]....
The way the app works is there are two modules that work together on the page. One is a selection grid and the other the detail form which shows the details from the selected item in the selection grid. If a user is in a limited role they can only see the data of the default selection and they do not see the grid to select from. It is under this circumstance that I get the error and the detailed module is not rendered. However if I break the code and skip over line 139 to line 140 the detailed information shows correctly. Otherwise I do not even see the detailed form. Based on that I know the detail form is working correctly but is not rendered after this error occurs. In addition I am using this same logic with another detailed pain that works correctly under both roles.
I can not seem to narrow in on any code that is causing the issue. For one thing I have no idea as to where the ScriptResource.axd is created. I also do not see where there is any settings for the tab control for submitions and I am not able to find an "OnSubmitStatements" in my code.
Ik keep getting this sort of errors when using Ajax controls.The colorpicker extender and the Cascaded dropdown generate this kind of error in my application.I have a scriptmanager in my masterpage.I already tried using a scriptmanager proxy.What could cause these errors?I have the controls inside template fields of data presentation controls.
View 2 RepliesI'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){
Iam using AJAX HTML Editor in my project. Initially i made the HTML Editor as invisible and if i click on the button the HTML Editor shoud be visible but when i click on the button iam getting this errorr "Sys.Extended.UI.HTMLEditor.Editor is null or not an object".
View 1 RepliesWhile testing an AJAX enabled web app I sometimes stumbled upon this script error: 'this.get_element().style' is null or not an object. It was a hard nut to crack this one.This was the actual message
'this.get_element() is null or not an object'
The situation:AJAX Enabled web app using slider extenders . In some circumstances a script error is generated. In most cases it is not.
The reason:It turned out that the error happens at times when a new Postback is triggered while a previous one hasnt finished yet. That is quickly changing the sliderhandle's position in this scenario. The Postback where triggered because i had set the AutoPostBack property of the extended TextBox to "true".I have some code running inside the event handler
have a problem on my application, i am using LightBox javascript that is using prototype.js library, and when i open any pop up that is having script manager it generate this error:Microsoft JScript runtime error: Sys.InvalidOperationException: The PageRequestManager cannot be initialized more than once.I know that is because i have scriptmanager on the parent page that opened the pop up and its something relates to prototype.js but i dont know the connection!
View 3 RepliesThis is the following structure of my solution explorer.
base directory -> i have a login.aspx and a reference directory which refers to ajax toolkit. The ajax toolkit works fine here.
private directory -> i have my homepage but the ajax toolkit doesn't work here. the above error is shown at this location :-
(function() {var fn = function() {$get('ToolkitScriptManager1_HiddenField').value = '';Sys.Application.remove_init(fn);};Sys.Application.add_init(fn);})();Sys.Application.initialize();
Sys.Application.add_init(function() {
$create(Sys.Extended.UI.TabPanel, {"headerTab":$get("__tab_TabContainer1_TabPanel1"),"ownerID":"TabContainer1"}, null, {"owner":"TabContainer1"}, $get("TabContainer1_TabPanel1"));
});
I have one web.config in the private folder . This is the structure :-
<configuration>
<appSettings/>
<connectionStrings/>
<system.web>
<authorization>
<deny users="?" />
<allow users="*" />
</authorization>
</system.web>
</configuration>
If i allow all users to access this folder or remove this web.config file, then the ajax toolkit works. I need to protect this folder and i am using form authentication. Could someone point me where i went wrong. Kindly keep in mind that i am new to asp.net.
i use accordion from ajax toolkit it work correctly when i use outputcash it gives me this error:

View 2 RepliesI decided to use the CalendarExtender on a project and I converted it from VS 2005 to Web Developer 2010 Express. I initially added the AJAX toolkit for ASP.NET 4.0 and the calendar extender worked fine. However, I realised that the server didn't have ASP.NET 4.0 installed and I thought it would be simpler to add the toolkit for 3.5 instead and change the target framework to 3.5. I tried and then the CalendarExtender did't work at all. When you click the textbox nothing happens. There is the error on page - 'sys.extended.ui.textboxwrapper is null or not an object'
I tried switching the project back to 4.0 and using the other one and that no longer works for some reason. The same in 2008 Web Developer Express. I've clearly done something wrong along the way, but I can't work out what it is.
Here's the source for a page on a test Web Developer 2008 Express project.

I am using some AJAX and some JQuery for Login panel animation in Master page.Also in my home page I am using AJAX Tab container.It works fine when I run the application without login.If I logged in I got the following error when I put the breakpoint into my code,
Microsoft JScript runtime error: 'document.getElementById(...)' is null or not an object,It shows at the following Line at the Home[dynamic] page.
document.getElementById('ctl00_sdfsf').dispose = function() {
Array.remove(Page_ValidationSummaries, document.getElementById('ctl00_sdfsf'));
}

this code give that solution.but if any one of the field have null(example:r.urrQuickLinkRights contain the NULL) then only it will throw error like Object reference not set to an instance of an object.
i have an application wherein i have incorporate a "Remember Me" feature for the login screen. I do this by creating a cookie when the user logs in for the first time, so next time when the user visits the site i get the cookie and load the user information.
i have written the code for loading user information in a common class in the App_Code folder...and all my pages inherit from this class.
code for loading the user info is as follows:
public static void LoadUserDetails(string emailId)
{
UsersEnt currentUser = UsersBL.LoadUserInfo(emailId);
if (currentUser != null)
HttpContext.Current.Session["CurrentUser"] = currentUser;
}
Now the problem is i get an "Object reference" error when i try to store the currentUser object in the session variable (even though the currentUser object is not null). However the password property in the currentUser object is null.
I'm getting frustrated with all this.
In my new webpage version I've added ajax toolkit 4.0 and runing framework 4.0, there seems to be some problems with the ToolScriptManager CombineScripts.
I have a MasterPage that all pages derives from and in this MasterPage I have a ToolKitScriptManager with LoadScript.....="false" CombineScripts="true". In my masterpage I've added a ModalPopUpExtender
When I start the webpage I can't show ModalPopUp (www.url.com) but if I go to any other page it works ex. (www.url.com/testpage/), if I disable CombineScripts="false" the the starting page works but then I get so many more httprequests.
i am using urlrewritingnet for url rewriting. at one of my page i am using auto complete extender . it works fine for first page weirdly because also that page is getting url rewriting.
now let me explain you
my normal page is
domain/Pokedex.aspx
here what i do for url rewriting
[Code]....
ok now problem does not happen when i type this : domain/Pokedex.aspx. but i when i type this problem occurs : domain/Pokedex-2 which is equal to domain/Pokedex.aspx?page=2. here is the problem screen shot but when i type this problem does not happen : domain/Pokedex.aspx?page=2 so it is about url rewriting i guess
I have a problem with the Ajax ComboBox from the Ajax Control ToolKit. When I want to erase the text in the ComboBox, I got this error:
"Microsoft JScript runtime error: '_optionListItems[...].text' is null or not an object". I only get this error when deleting the content of the Combox is the first action I do on the ComboBox. If I overwrite the text by entering something else before deleting this text, I got no error.
m getting this error again and again. i m also using the ajax modalpopup extender in my page ..
