Refresh image causes Sys.WebForms.PageRequestManagerServerErrorException

[Brian Goldman]

Hello,
I have a captcha control on a form with the refresh image link enabled. If the page name is not in the url the refresh image throws an error (listed below) but if the page name is in the url it works fine.
So
http://www.nirvanawebworks.com/company/contact/ throws an error
and
http://www.nirvanawebworks.com/company/contact/default.aspx does not.

Is there a way to make it work without the page name?

Thanks,
Brian

Hello Brian,

I have tried reproducing the issue you described, but to no avail. Nevertheless, we have already encountered problem, similar to the one you are having. It is possible that it is caused by IIS of Windows 2008 server and is executed when the URL doesn't contain the exact page. You can ensure that you are experiencing the same issue by adding a RadButton to your page and checking if the server-side event handler is executed.

Here you can find article, which discusses such a problem.

In case the provided information is not related to your issue, please try modifying the sample I have attached so that it matches your problem or prepare and send us sample, runnable project, which isolates the problem so that we can inspect it locally and determine the cause.

Best wishes,

I spent hours and hours on this. I deleted the site from the server and set it up again. I tried a different server, etc. Everything I could think of. Finally I started removing things from the web.config one by one to see if that would help. Well I found the problem. I removed this from the web.config and it started working!

<httpModules>
  <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule" />
  <add name="RadCompression" type="Telerik.Web.UI.RadCompression" />
</httpModules>

Any idea why this is happening? I used the telerik config project wizard and that is what entered these lines into my config file.

Thanks,
Brian

Hello Brian,

  We are glad to hear that you succeeded in resolving your problem. It is most peculiar and this is the first time such an issue has been reported. I am sorry to say that for the time being I cannot provide a firm answer for the exact cause for this behavior. 

Could you please verify that both the RadUploadModule and RadCompression need to be removed so that the issue is solved and if not, which one is the cause.

You may also check if the problem reproduces when you deploy in your project an UpdatePanel, containing RadControl, for example RadButton, because update panel is used to refresh the image of RadCpatcha.

Please note that at the current state of affairs I don't have much information about your setup, so it will be much appreciated if you would provide more detailed description of your scenario.

Best wishes,
Slav

The problem is

  <add name="RadCompression" type="Telerik.Web.UI.RadCompression"/>

If I add that I get the error.

Hello Brian,

You are probably facing this breaking change in .Net 4.0. Check the Known Issues section of this help article for more details and solution.
I hope this helps.

Kind regards,

Thanks Pavel ,
The issues discussed seem to refer to IIS 7 and IIS 7.5. I'm running IIS 6 on Windows 2003. I did try the workarounds mentioned but they caused worse problems not a solution.

Any other ideas?

Thanks,
Brian

Hi Brian,

In that case you can try adding Action="Default.aspx" to the form tag of the problematic page. Let me know if that helps.

Hi Pavel,
Yes, that seemed to have done the trick. Thank You.
