AJAX :: Microsoft JScript Runtime Error: Sys.WebForms.PageRequestManagerServerErrorException: '<combo Box

Oct 26, 2010

We have used Ajax toolkit combo box in one of our application. We have used two Ajax toolkit combo box in an aspx page. Both combo boxes are populated while loading the page. Combo box 1 has list of items and based on combo 1 selection, combo box 2 is populated. This requirement is implemented within the updatepanel and only partial page rendering is done on combo box 1 selection.

This is working fine when the list of items are populated at the time of page load.

We have provided an option to add new item in combo box 1 and combo box 2. When new item is added in combo box 1, it calls iteminserted event. Since it is a new item, it does not have corresponding items in combo box 2. When we add new item in combo box 2 it submits the page (partial rendering). While it gets submitted it throws following JScript error.

"Microsoft JScript runtime error:

Sys.WebForms.PageRequestManagerServerErrorException: '<combo box id>' has a SelectedIndex which is invalid because it does not exist in the list of items.

Parameter name: value"

We are unable to resolve this issue.

AJAX :: Getting Microsoft JScript Runtime Error

Feb 10, 2010

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.

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:

AJAX :: Microsoft JScript Runtime Error: 'WebPartManager' Is Undefined

Dec 30, 2010

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)

AJAX :: Microsoft JScript Runtime Error: AjaxControlToolkit Requires 4.0 Scripts?

Jan 14, 2011

Im am getting the following error:

Microsoft JScript runtime error: AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the AjaxScriptManager in System.Web.Ajax.dll, or use the ToolkitScriptManager in AjaxControlToolkit.dll.

I am using ASP.Net 4 and the AjaxControlToolkit .net 4 dll. On my page I am using the ToolkitScriptManager.What I don't understand is that it works without any issue on my development machine in Visual Studio and if I publish it to IIS on that machine. If I run it on another machine I got it also works without any issue. When I copy the published application to my web hosting provider, I am getting this issue.I was getting a SecurityException initially when the site loaded the AjaxToolkit assembly, but now that seems to have just gone away, but I still get this issue.

AJAX :: "Microsoft JScript Runtime Error: Sys.ArgumentUndefinedException: Value Cannot Be Undefined?

Oct 6, 2010

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.

AJAX :: Microsoft JScript Runtime Error: 'Sys.Extended.UI' Is Null Or Not An Object

Mar 20, 2010

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.

AJAX :: AJAX Modal Error - Microsoft JScript Runtime Error: Sys.ArgumentNullException: Value Cannot Be Null

Mar 20, 2010

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...

AJAX :: Microsoft Jscript Runtime Error Client-side Framework Failed To Load?

Feb 4, 2010

I have tried every single method in almost every post available on both Bing and Google. And I still get this error.I thought it was something in my website or web.config, so I opened up VS2008, selected to create a new ASP.NET Website and let it go..Here is the default.aspx page and web.config created by VS2008. Without modifying anything other than chaning the website properties to .NET 3.5 instead of .Net 2.0, I still get the error on this website when I hit F5. I have other websites with the ajax update panel and script manager on this server that work fine and have tried the web.config from them on a new project. But any new projects still do not work.I have verified that the settings for the working project as well as this new project in IIS are the same. Can anyone tell me why I am getting this error and theSys Undefined error?

Microsoft JScript Runtime Error: 'Sys' Is Undefined

Oct 4, 2010

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.

AJAX :: Getting "Microsoft JScript Runtime" Error

Oct 1, 2010

I have added MaskedEditExtender and MaskedEditValidator controls from the Ajax Toolkit for .NET Framework 4.0 to my textboxes to provide enhanced functionality. However, since I've done that I am getting the following error in Visual Studio when I visit the page containing these controls.

Microsoft JScript runtime error: '2.length' is null or not an object

This is the information from the script page that Visual Studio breaks in.

When I right-click on the tab in Visual Studio and choose "Copy Full Path" it gives this.
^TransientScriptDocument248.aspx

When I hover over the tab in Visual Studio it gives this (as much as I could see in the tooltip).
LocationDetail.aspx?_TSM_HiddenField_=ajxToolkitScriptManager_HiddenField&_TSM_CombinedScripts_=;;AjaxControlToolkit,+Version=4.1.40412.0,+Culture=neutral,+PublicKeyToken=28f01b0e84b6d53e:en-US:acfc7575-cdee-46af-964f-5d85d9cdcf92:de1feab2:f2c8e708.....

This is the piece of code from line 21 of the file above, where Visual Studio breaks. if(t.length<n[2].length)

This did not exist before adding these controls to the page. This combined with it mentioning the Ajax Toolkit Script Manager makes me think it is indeed from these controls.
