Web Forms :: "Sys" Is Undefined Error "client-side Framework Failed To Load" On Webpage
Jul 16, 2010
When I open my webpage locally on my computer, the webpage does not through any error but from the server, I get those: Message: ASP.NET Ajax client-side framework failed to load.
Message: 'Sys' is undefined
Message: 'Sys' is undefined
In the web.config file I changed: <compilation debug="true"> to <compilation debug="false"> wich solved the first error(ASP.NET Ajax client-side framework failed to load.)
1. I wonder if that is okay to solve that error like that?
2. Then I wonder for the 'Sys' is undefined, what is causing that error. I googled and could solve the first error but this Sys error it seems to have countless of solutions that have not worked for me, so I might wonder what can cause this
I have seen all the previous posts but did not got any solution. I am using URL routing and the website runs fine untill i change the global.asax file. Till then all the configurations runs properly. The web.config is also correct and ihave added the modules required for URL routing. Now when i change the global.asax file, i get the following error on my masterpage:
//<![CDATA[ if (typeof(Sys) === 'undefined') throw new Error('ASP.NET Ajax client-side framework failed to load.'); //]]> [code]...
I am using VS2010, .Net 4. I am trying to add a ScriptManager to my page, so I can reference an AJAX Enabled WCF Service. When I add the ScriptManager control to my page and view it - I get the error shown below. I have no clue how to resolve it. I get the error by simply putting the control on my page (not reference the WCF Service).
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?
The HTML source between the original and the new project are identical, save for the few lines of code that throw this error. The web.config files are identical.
i am facing a serious problem with ajax that ASP.NET Ajax client-side framework failed to load and also sys is undefined.i have asp.net 3.5 service pack 1 installed on server.also using toolkitscriptmanager on pages have checked iis for .axd extension.It is there.system date is okk.have latest version of ajaz control toolkit.on localhost it is working fine.but giving error on live server.
what needs to be done since I'm trying to interpert other people's code. Anyway, here is my dilimma. I am running Windows 7 Professional x64 with IIS 7 and coding in VS 2010 using .NET 4 for the ASP.NET site. I installed the AjaxControlToolkit.NET4 in VS 2010 with no issues. I even used the Calendar Extender with a text box and image with no problems, at least when debugging. When I go to publish it out on my test IIS7 site
I have uploaded my application made in vs 2010 and asp.net 3.5 framework on windows Server 2003 R2. As i run my app i get an error1.ASP.NET Ajax client-side framework failed to load.2. sys is undefined.I already have 3.5 framework installed on my server and th latest version of ajax tootlkit dll added to my app.
I had a working .net website in a working VS2008 environment on a WinXP machine.Moved to Win7 machine, and now this maddening error comes up. I have no clue!Since the site and the development environment were working before, I can only assume it is an environmental problem. But what?
I have developed an ERP module wihch runs on intranet. with ASP.NET /AJAX. It runs perfectly in my localhost. IIS. But when I try to run it on my development, It gives some errors of AJAX. undefined string literals. Microft ajax client-sisde framework failed to load. sys is undefined.. I've check my web.config file. But I cant find any problems into it.
I originally wrote an ASP .NET 3.5 intranet website on a .NET 4.0 machine running IIS 5. To alleviate the problem, I figured I'd rewrite the website in VS using 4.0. This seemed to fix the issue, but then it starting reoccuring again. I currently have 8 users for my website, which utilizes the AJAX dropdownextender. Ajax 4.0 is installed on the machine and all the users (including me) can access the website via the intranet and rarely have problems. The only issues arise in the morning when the users 1st access the site. It will occassionally give errors stating"ASP.NET Ajax client-side framework failed to load","'Sys.Extended.UI' is null or not an object", or"'Sys.WebForms.PageRequestManager' is null or not an object". All these errors arise from the framework incorrectly loading. It is typically cleared up right away with a page refresh. Unfortunately, most of the users aren't the most computer literate, so are unaware of issues that arise. I just want to know if there is a way to fix this issue. I've been researching this issue alot, but never got a straight answer. If any other information is necessary, please let me know.
I have been struggling with this issue for a couple of days now. I followed the creating a custom control extender for VB shown here http://www.asp.net/ajax/tutorials/creating-a-custom-ajax-control-toolkit-control-extender-vb. However, I receive the following error when I try to load the page:Uncaught ReferenceError: AjaxControlToolkit is not definedThe error references line 74 in the DisabledButtonExtender.js file.Here is the Default.aspx page where I am using the Custom Control Extender
I know that setting runat="server" and specifying an id for an iframe control, makes it accessible on the server side but what I need is that the iframe source contents get loaded at server side not client side.Is it possible?Why do I need it this way?
Currently my iframe source site is configured for ntlm authentication and sso which means it would read my windows credentials whereas I'd need it reads the credentials provided by the site which hosts that iframe.
Currently using VS 2005 & MS SQL 2005 Server with a Windows 7 OS and I am unable to generate Update/Insert/Delete queries when using the TableAdapter wizard. I am able to create the Select statament. This is the error message that is displayed in the TableAdapter wizard on completion for each of the Update/Insert/Delete queries "failed to find or load the registered .net framework data provider"
I have seached the web but no one seems to have seen this same issue.
If you know what is causing this let me know. I didn't have this issue while running a XP or Vista OS.
I m using site login Control in my login.ascx file and disaplaying login control in Div so if there is login link in page and i click on that then Login Div will popup which is site login.May i know how can handle error like username or password is incorrect on client side instead server side?
I have 2 gridviews in an aspx file. The First one is master grid, and the second one is detail grid. (such as Customer and it's Invoices) First, I load data into master grid. I use FireBug and notice that every row has it's row id, such as:
Then, in master grid, I select a buttonfiled in a row to load the second gridview.Every thing alright, the second grid has it's row id But The master grid lost all row id that I dont know the reason why?
I'm curently developing web application which uses standard form authorization and, of course, server session objects (quite classic app). Now I'm developing client side component, which base functionality is to allow users to acquire tiif/jpg/pdf document from scanner (client side) and send it to server. Because of scan complexity and need for very user friendly interface i decided to implement Activex object (object written in .net 2.0). Until now all was ok, so I have got activex which succesfully registers and scan documents on client - but i cannot manage with sending files to server.
My concept of sending files was like that:
- preparing Upload.aspx web page wich is used for reciving files sended by POST method and saving files in database (of course to proper save in database i need some current user context information) - in ActiveX i decided to use System.Net.HttpWebRequest object to prepare and send data the problem was third point:
- i thought that in-proc activex object would "derive" web session form web page activex is placed on - but i was wrong (or i made it wrong). Whenever i send request form Activex, in response i got login.aspx page - so it looks that new session is created and new authorization is needed.
I was trying to pass to my Activex values stored in "ASP.Net_SessionId" and ".ASPXAUTH" cookies, as i found that these are the values identifying session and athorized user - but with no luck.
I think, that becaause HTTP is stateless protocol all information needed to "connect to/share" existing session on IIS server need to be included in request data, so there must be way to add these information to request sended from my activex.
I would be very grateful, if someone could provide me information what should i add (headres/cookies/etc... ?) to my request data so it could share session from "parent" web page.
I've run into this bizarre situation wherein I get the below error if I set page size other than 5 in the page using this control.
"Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request."
This GridView is a hierarchial type. I add a new GridView below each row in the webcontrol overriding OnRowDataBound.
