  Unable to cast object of type 'System.Web.Configuration.ScriptingScriptResourceHandlerSection' to...

  Oct 18, 2007 07:32 AM|AntLaC|LINK

  Hello,

  I get this lovely error whenever I attempt to load an AJAXToolKit ScriptManager. It is the only one I have on the page. If I use the regulare script manager, my extenders don't detect it. I'm placing the ScriptManager just after the <Form> tag.

  The frustrating part is that it works when I preview it in the browser from my development machine it works, but once I place it the live server, it crashes on me [*-)].

  I've installed all of the .dlls in the proper places.

  Also, I'm trying to attempt to do this when creating a new site with the AJAX ToolKit enabled template, still to no avail.

  AntLaC, WebApp Developer

  Hi Antlac,

  Your problem seems that it is mainly caused by the System Enviroments.  Ajax-enabled program runs depend on .Net Framework2.0 or above.(If your application developed based on .NET Framework 3.5, please make sure it should be runs on .Net Framework 3.5) Sometimes , the newly created ajax application runs on .Net Framework 1.1(IIS).  So please check it first.  Second, you should check whether Asp.Net 2.0 Ajax Extensions V1.0 has been installed or not. 

  Best regards,

  Jonathan

  Instead of starting another thread...I have the exact same error

  There is no source involved.

  Create a ASP.Net (3.5) page in VS08beta,

  place a ToolScriptManager on the form with a TetBox and a CalendarExtendar targeting the TextBox and the 'View in Browser'  and it will give you

  Thoughts?

  Hi MasterControlProgram,

  Please change the web.config settings, I suspect your web.config is based on the .NET Framework 2.0. Here is the sample.

  Hi MasterControlProgram,

  Please make sure that your application runs on .NET Framework 3.5 and your Ajax Control Toolkit's version is compatible with the Framework. The web.config file that I posted is based on Ajax Control Toolkit V10920.  Also, you should pay attention to the settings that you added to the web.config for your needs.

  Best regards,

  Jonathan

  Oct 25, 2007 03:11 PM|mastercontrolprogram|LINK

  Jonathan - followed link, grabbed the suggested files, installed and created new tab with the 10109 version of the AJAX components.

  Maybe we should start from the top. 

  From what I've seen in the MS training videos online (for example) the AJAX calander control is dragged onto the screen, targeted to a text box and "View in browser" ... done, works.  So I tried same by following along

  Here're the exact step I've taken

  Open VS2008beta

  Select .Net framework 3.5 from the dropdown

  create new website

  open the aspx page

  drag a ToolkitScriptManager (v. 1010920) onto the page

  drag a textbox onto the page

  drag an a calender control (v. 1010920) onto the page and set its Target to TextBox1

  do nothing else, build the page, then view in browser....error (above)

   

  I am very new to AJAX in ASP.Net (coming from .Net 1.1) so maybe there are some other things (configuration? installations?) I am not aware of.  Any hints or shoves in the right direction are appreciated.

   

  Thanks!

  MCP

  Hi MCP,

  It is such a weird issue.   I have tested on my local machine with VS2008 + Ajax Control Toolkit V10920 and it works  pretty fine. Here is the sample.

  <%@ Page Language="C#" %>

  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

  <script runat="server">

  </script>

  <html xmlns="http://www.w3.org/1999/xhtml">
  <head runat="server">
      <title>Untitled Page</title>
  </head>
  <body>
      <form id="form1" runat="server">
          <ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
          </ajaxToolkit:ToolkitScriptManager>
          <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
          <ajaxToolkit:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID="TextBox1">
          </ajaxToolkit:CalendarExtender>
      </form>
  </body>
  </html>

  Please recompile the Ajax Control Toolkit source code and run its CalendarExtender Sample to see whether it works properly or not. If it works, we can come to a conclusion that your enviroments are ok.  So we can copy the sample website's web.config to your newly created website and refrence the AjaxControlToolkit V10920.  AjaxControlToolkit V10920 has two versions. One is for .Net Framework2.0 and another is for .NET Framework3.5.  So please make sure you are using the right version which should work on .NET Framework3.5.

  Here is another useful hint.  

  I hope this help.

  Best regards,

  Jonathan

  "Please recompile the Ajax Control Toolkit source code and run its CalendarExtender Sample to see whether it works properly or not. " - Did, and does when I run the sample site, all works 

  "If it works, we can come to a conclusion that your enviroments are ok." - Agree

  "So we can copy the sample website's web.config to your newly created website... " - Did, same results below as above...

  "...and refrence the AjaxControlToolkit V10920.  AjaxControlToolkit V10920 has two versions.

  Results...

  Hey MCP,

  I  had to add an assembly binding redirect. I added it just before the closing configuration element.

  Now though, it doesn't work in VS2008, but it does in the live server. So, I have 2 versions of the web.config.

  Hopefully this will work for you.

  Please mark this as answer if it worked. [8-|]

  Hi MCP, 

  mastercontrolprogram

  If I download the 'AjaxControlToolkit-Framework3.5' do I need to repoint or create a new AJAX toolbar in my dev env?  Do I need an AjaxTollbar2.0 and a AjaxToolBar3.5?

  Actually, it is based on the .NET Framework version that you use on your project.  When use different AjaxControlToolkit, please recreate the Toolbox.  Hope this help.

  Best regards,

  Jonathan

  Looks like grabbing the 10920 version did the trick.  I won't tell you whatelse I did that may or may not have helped (uninstall, reload) but appears to be behaving as described by M$.

  Thanks!

  I also had this error when deploying to a web server, although it worked fine when debugged from within VS 2008.  In the end I found that I had duplicate dependentAssembly tags in the web.config:
  

  <dependentAssembly>
                  <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35"/>
                  <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
  </dependentAssembly>
  <dependentAssembly>
                  <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35"/>
                  <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
  </dependentAssembly>
  

  Removing one of them fixed the error.

  I actually have the same problem and I know I already have System Web Extensions 1.0.61025 already installed in the SP instance and working with other web parts targeting ASP.Net 2.0.  This new web part project is targeting ASP .Net 3.5 and is attempting to use System.Web.Extensions 3.5.  So the question is can they work together?  Does the previious posts dependentAssembly mean that I can with this entry?  If so where does it go?

  Sorry Thanks my guess was the solution - just don't try putting web parts created using the ASP.Net 2.0 Extensions on the same page with ASP .Net 3.5 Ajax Extensions....  Strange things happen if you do
