I've tried them all

Jan 02, 2007 08:12 AM|LINK

Hi,

I created an ajax web site and when viewing in browser I got the 'Sys is undefined error message', the details pointed to lines 40 & 98 of my source code

line 40 - Sys.WebForms.PageRequestManager._initialize('ScriptManager1', document.getElementById('form1'));

line 98 - Sys.Application.initialize();

I've tried all the above fixes in this thread but have not been able to solve this problem

Need help!!

Thanks

Tim

so i ran into a new scenerio for this error, and it has to do with Vista RTM

I haven't been able to get debugging working at all until i ran into this blog entry a few hours ago (http://www.thousandtyone.com/blog/CategoryView,category,Vista.aspx), so when i switch into "Classic ASP.NET" app pool, debugging works, but good ol "sys undefined" sticks it's ugly head and renders my MS AJAX stuff useless (and it doesn't matter whether i view the page with or without debugging running)..... going back to the integrated pipeline default IIS7 pool fixes the AJAX but alas, prevents debugging from working...

Re: KB912812 may fix it.

Hope this helps someone. These 3 entries fixed my app. I looked at a ajax enabled web.config and took these entrues and my problem disappeared.

<httpHandlers>
  <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
</httpHandlers>


<httpModules>
   <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</httpModules>
<assemblies>
  <add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</assemblies>

I'd also like to note for people changing their IIS configurations, this shouldn't be need on II6 and above as the above entries tell the .NET to add these handlers.

Delete element <system.webServer> from Web.config. It helped for me after trying all suggestions on this site.

I solved the problem!

Simply create temporary web site from Ajax Control Toolkit Web Site template and copy some sections from web.config to web.config of your web site (<configSections>, so on).

Copy bin dll file also.

Hi, LSerge

Good solution!

I created a temporary web site from ASP.NET AJAX_Enable Web Site template and copy the web.config file, replace the web.config of my web site, and it worked fine!

Thanks and sorry for my poor English.

I experienced the same problem.

Now, as far as my case is concerned, the replacement of <system.webServer /> can solve the problem.

My environment is Windows Vista + (VS2005+SP1).

BEFORE

   <system.webServer>
    <validation validateIntegratedModeConfiguration="false"/>
    <modules>
      <add name="ScriptModule" preCondition="integratedMode" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
    </modules>
    <handlers>
      <remove name="WebServiceHandlerFactory-ISAPI-2.0"/>
      <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode"
           type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      <add name="ScriptResource" verb="GET" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
    </handlers>
</system.webServer>

AFTER

<system.webServer>
    <validation validateIntegratedModeConfiguration="false"/>
    <modules>
      <add name="ScriptModule" preCondition="integratedMode" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
    </modules>
    <handlers>
      <remove name="WebServiceHandlerFactory-Integrated"/>
      <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
    </handlers>
</system.webServer>

Hoping this will be adaptive,

ym

Here's the solution for the main issue: http://dennylove.blogspot.com/2007/01/sys-is-undefined-ajax-10-rc.html

However, I'm now getting a different problem.

"Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500" If anyone knows what this is I appreciate it.
