RadUpload Ajax callback error. Source url returned error: 500

[Roland]

Hello Telerik team

  when I upload a document, instead of the progress bar, I get the following pop-up error message.

------------

RadUpload Ajax callback error. Source url returned error: 500 

Internal Server Error 

../../Telerik.RadUploadProgressHandler.ashx?RadUrid=8d310557-c6f8-4bc1-949e-cc930cbe29fd

Did you register the RadUploadProgressHandler in web.config?

----------

  my aspx page resides inside sharepoint.

 my web.config has the following entries:

</httpModules>
<add name="RadUploadModule" type="Telerik.WebControls.RadUploadHttpModule, RadUpload.Net2" />
</httpModules>

<httpHandlers>
<add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" />
<add path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" validate="false" />
    </httpHandlers>

thanks for your help-

Roland

Hello Roland,

The module that you have registered is for the class RadUpload, not for RadUpload for ASP.NET Ajax.

I suggest that you remove the handlers from the web.config and register them again using the RadProgressManager smart tag. You can also take a look at this help topic.

Thanks for your response.
 I followed the instructions: now web.config now has the following:

<httpModules>
<add name="RadUploadModule" type="Telerik.WebControls.RadUploadHttpModule, RadUpload.Net2" />
</httpModules>

<httpHandlers>
<add path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" validate="false" />
</httpHandlers>

 I now get the following error:

---------------------------
RadUpload Ajax callback error. Source url was not found:  

/Telerik.RadUploadProgressHandler.aspx?RadUrid=2b0f48b9-5969-47de-937b-efc7ff6b34e1 

Did you register the RadUploadProgressHandler in web.config? 

Please, see the help for more details: RadUpload 2.x - Using RadUpload - Configuration - RadUploadProgressHandler.
---------------------------
Its worth noting that I just want to use telerik's progress bar only. i plan to using asp.net upload control.
 thanks again.

Hello Roland,

Do you use RadUpload for ASP.NET or RadUpload for ASP.NET AJAX? As far as I can see from your web.config, these are the entries for the classic upload (for ASP.NET). However, this is the forum for the AJAX upload. This is why I have given you the wrong link. I have attached sample web.config file containing the correct declaration for the classic version.

Just in case anyone else comes across this, if you are running IIS 7 you need to use this post

We are having a similar issue. The error message is:

RadUpload Ajax callback error. Source url returned error: 12017
Unknown
../Telerik.RadUploadProgressHandler.ashx?RadUrid=e098cfbd-d9c1-48a0-92dd-2f93b3f5825
Did you register the RadUploadProgressHandler in web.config?

Our web site is running on IIS 7.5.

Any suggestion to fix this issue?

Thanks!

Hi Roland,

Please make sure that you have the following handler registered in the handlers section of your web.config:

<add name="Telerik_RadUploadProgressHandler_ashx" verb="*" precondition="integratedMode"
    path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" />

Does the problem persists?
