WCF / ASMX :: Microsoft JScript Runtime Error: 'Sys' Is Undefined?
Jan 3, 2011
I have to call a web service from JavaScript using .net framework 2.0 and Visual Studio 2008. I am able to do this successfully using .net framework 3.5 and Visual Studio 2008, but since the application is in .net framework 2.0, I downloaded the ASP.NET 2.0 AJAX Extensions.When I run the application I get the above error at
Sys.WebForms.PageRequestManager._initialize('_scriptManager', document.getElementById('form1'));

I am having problems with an intermitent error in an ASP.Net Ajax enabled website. The error I am receiving is the old faithful "Microsoft JScript runtime error: 'Sys' is undefined" error. Googling this error usually turns up the suggestion to add the correct "httpHandlers" and "httpModules" into the "web.Config" file. The web.config file for this project already has the following lines for those two sections. See below:
[Code]....
The error is intemittent, it sometimes does not present at all when debugging a page, and other times it will present constitently for anything up to a day or so?
BTW, we are using Telerik ajax controls on the page. One of our custom JavaScripts does render before the scriptmanager. ahve tried using both "RadScriptManager1.RegisterClientScriptBlock(...)" and "ClientScript.RegisterClientScriptBlock(...)" but both seem to render the script block above the "Sys.WebForms.PageRequestManager._initialize(...)" line.

I have used url routing on my website to route the user to his/her profile page once he has entered username in the url. The whole website runs fine without any problem except for the case after url routing. When a username is typed in the url after the website name then the routed aspx page opens up giving the following error:
Microsoft JScript runtime error: 'WebPartManager' is undefined
In this particular child page i have used a webpartmanager inside an update panel as it is the right approach which i found out over the web. The code used in global.asax file is:
void Application_Start(object sender, EventArgs e)
{
RegisterRoutes(RouteTable.Routes);
}
public static void RegisterRoutes(RouteCollection routes)

The above error occurs when the following code is run:
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RequestCompleted);
Within this block:
<script language="javascript" type="text/javascript">
var postBackElement;
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RequestCompleted);
Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(InitializeRequestHandler);
function InitializeRequestHandler(sender, args) {
//set the postBackElement
postBackElement = args.get_postBackElement();
}

I am using Windows 7 PRO, 64 bit, with Internet Explorer 8, Visual Studio 2010
Every time I run any ASP.NET application in debug mode, right after it loads any of the pages, then I get 2 errors:
Error: Microsoft JScript runtime error: 'JSON' is undefined
I click "Ignore" error, then I get this: Microsoft JScript runtime error: 'undefined' is null or not an object
And the file is from Internet Explorer:
how to fix this ?

i'm trying to use the ajax control toolkit but each time i'm trying to run my project i'm getting a:
"Microsoft JScript runtime error: Sys.ArgumentUndefinedException: Value cannot be undefined.
Parameter name: type " Error.
if i hit the continue button the page loads but without the functionality of the control,the control that i'm trying to use is the AutoCompleteExtender.
i followed all the video tutorials and read many post about this toolkit but found nothing about this error.
i tried this on both web developr 2008, 2010 and visual studio 2008.

We've got a VS 2008 ASP.NET app, which is running internally. I've had some older versions of the pages on my system, and a colleague of mine has been updating them. Recently she started to this error:
Microsoft JScript runtime error: RSClientController is undefined. And after that several other errors start popping up, as the page is rendered. (While debugging the page, it stops at several lines to complain about this and other items that were being rendered.)
Anyway, once I got the latest versions of everything checked into source control, I too started to get the same error message. What causes it? How do you fix it?

I used the following function in my ASP.Net Project (which contains ajax controls)
[Code]....
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
I searched online for solution and got to know its the problem of asp.net ajax. None of solutions (that I found like Add EnableViewState=false, etc.) worked for me.

I have created an AJAX Server Control Extender which uses the Sys.Timer-object in the client behavior. It worked at first, but suddenly I started to get "Microsoft JScript runtime error: Object expected" when running the page with the extender. When debugging, I see that the line - this._timer = new Sys.Timer(); - in my .js-file which fires the error is the bold line in this function:

I have an asp:BulletedList controls with AJAX:PagingBulletedListExtender on my aspx page.
It gives error as: Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors. Parameter name: element
If I removed, the asp:BulletedList controls and AJAX:PagingBulletedListExtender from my page then page run without any error.
I am not getting the cause of the error.
