Hi,

I have a site where I am using Dynamic registration and Dynamic Forms.  I was having some issues with the website and I went from ASP 4.0 to ASP 2.0 and then back to ASP 4.0.

The forms where working great and now I get the following message when I go to the pages that have the forms.


A critical error has occurred. Method 'get_EnableCdn' in type 'System.Web.UI.ScriptManager' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation.

I can't find much about this on other forums.  Any ideas?  I am assuming that when I changed ASP something got removed or added and now the forms are not working.

Any ideas?

Thanks
Ginnie

Hi Ginnie,

Can you please tell me your exact module versions from Host, Module Definitions and your DNN version?

Thanks,
Candace

Hi Candace,

DNN Version 05.06.02
Running on ASP 4.0
DF version 3.40.41
DR version 4.10.13

I see from another post that someone else had similar issue http://www.datasprings.com/products.../aft/21831 but cannot see a fix.

Thanks
Ginnie

Thanks, Ginnie.

Can you please compare your web.config, especially areas referencing "ScriptManager" and make sure it matches up with an out of the box web.config file. You will need to unzip dotnetnuke (after downloading it) and review the web.config file, then compare it to your file to see and fix the difference.

Please let us know what happens. Thanks!

Candace

Hi Candace,

I double check and it all matches, so I don't know what else can be causing this issue. Here is the detail of the error from the log

DotNetNuke.Services.Exceptions.PageLoadException: Method 'get_EnableCdn' in type 'System.Web.UI.ScriptManager' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation. ---> System.TypeLoadException: Method 'get_EnableCdn' in type 'System.Web.UI.ScriptManager' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation. at DataSprings.Modules.DynamicForms.DynamicForms.Page_Load(Object sender, EventArgs e) at System.Web.UI.Control.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace ---

and this is what I get for the page running Dynamic registration
DotNetNuke.Services.Exceptions.PageLoadException: Method 'get_EnableCdn' in type 'System.Web.UI.ScriptManager' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation. ---> System.TypeLoadException: Method 'get_EnableCdn' in type 'System.Web.UI.ScriptManager' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation. at DataSprings.Modules.DynamicRegistration.DynamicRegistration.LoadAllControlsAndFeatures() at DataSprings.Modules.DynamicRegistration.DynamicRegistration.Page_Load(Object sender, EventArgs e) at System.Web.UI.Control.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace ---

I looked in the bin folder and I don't have a system.web.extensions.dll file. Do I need this file?

Ginnie

One other thing. I just tried adding another form on a test page and I get the same error message.

Hi Ginnie - Our module uses 1.0 AJAX and I think you need to make sure you have this included in your web.config that 1.0 really should POINT to 3.5. I think that is what you would need.

Is this shared hosting or dedicated? You shouldn't have a problem with 4.0 framework and our modules so I think its related to AJAX which is why you are getting the ScriptManager issues.

Do you have this

Hi,

Thanks Chad. I had it set to 3.5 but it needed to be 4.0 as I am running 4.0 asp. I think we I did the change from 2.0 to 4.0 the setting did not move up to 4.0 and stayed to 3.5 which caused the error.

Thanks for your help.

Ginnie
