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.

I am working on ASP.NET 3.5, c#, visual studio 2010. I have made a master file and a default page that uses this master file. I have placed a couple asp:contentplaceholders in the master and corresponding code in the page that uses this master. I have also inserted JavaScript like this in the content page (and not the master):
<asp:Content ID="Content6" ContentPlaceHolderID="Mainpage" Runat="Server">
<script src="path1" type="text/javascript"></script>
<script src="path2" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
var options = {
//some java code
};
$(".mycssclass").effect(options);
});
</script>
</asp:Content>
On running the website I get the following runtime error in visual studio: Microsoft JScript runtime error: 'this.node' is null or not an object and it point to some function inside the JavaScript like this.node.onload=function(){..............//I am not a java guy so do not know much about this Where am I going wrong? Why does the site compile correctly but throw this runtime error? I also tried inserting this java code inside the master file in the <head>, but same error.
While testing an AJAX enabled web app I sometimes stumbled upon this script error: 'this.get_element().style' is null or not an object. It was a hard nut to crack this one.This was the actual message
'this.get_element() is null or not an object'
The situation:AJAX Enabled web app using slider extenders . In some circumstances a script error is generated. In most cases it is not.
The reason:It turned out that the error happens at times when a new Postback is triggered while a previous one hasnt finished yet. That is quickly changing the sliderhandle's position in this scenario. The Postback where triggered because i had set the AutoPostBack property of the extended TextBox to "true".I have some code running inside the event handler
This is the following structure of my solution explorer.
base directory -> i have a login.aspx and a reference directory which refers to ajax toolkit. The ajax toolkit works fine here.
private directory -> i have my homepage but the ajax toolkit doesn't work here. the above error is shown at this location :-
(function() {var fn = function() {$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:
Microsoft JScript runtime error: 'Sys.Extended.UI' is null or not an object

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 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.
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.
m getting this error again and again. i m also using the ajax modalpopup extender in my page ..
View 3 RepliesI have a <script> that contains this line: var tbl = document.getElementById("<%= this.tblSelection.ClientID %>"); but tbl always ends up being set to null. The table is declared like this:
<asp:Table ID="tblSelection" runat="server" CellPadding="2" CellSpacing="0"
cols="1" style="position: absolute; top: 0%; right: 0%">
Both the script and the table are in the same master page file. What could be causing this? I should mention that this script is executed on onload
My site was woking fine, now i noticed that i get an error "Microsoft JScript runtime error: 'null' is null or not an object" when i checked the view source, i saw the following system generated code

if (typeof(ValidatorOnLoad) == "function") {
ValidatorOnLoad();
function ValidatorOnSubmit() {
if (Page_ValidationActive) {
return ValidatorCommonOnSubmit();
}
else {
return true;
}

Modal not showing up when show is called, also error on loading page. Attaching code below, can anyone help me discover my syntax / logic issues here?
NOTE: Did some research on this before posting, some claimed it can be an issue of where the modal is placed on the page in relation to the update panel I am using. I have tried different placements of the modal extender and I also tried removing the update panel all together in hopes to at least see the modal show, no go...same issue. So with that, the issue shouldnt be around the use of the update panel...

I had to exclude several pages from my website to get it to run in vs 2008. When I finally got the home page to come up, I tried to type a character into the login box, and at the first character the probelm blows up:

I'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:
