Hi,
We have recently upgraded to SharePoint 2013 from SharePoint 2010. I have designed a custom ASP solution that uses Telerik Reporting. In SharePoint 2010, this has worked fine, but I am not having any success in 2013.
When I go to generate a report, the ReportViewer screen appears and nothing happens. No "Generating Report, Please Wait" message as there should be.
Currently this issue occurs ONLY in Internet Explorer. The reports generate without issue in Chrome and Firefox.
Using Fiddler and Internet Explorer and Chrome's debugging tools, I have found the following information:
Fiddler:
HTTP/1.1 401 Unauthorized
IE Debugging:
SEC7112: Script from http://xxx/Telerik.ReportViewer.axd?name=Resources.ReportViewer.js&optype=Resource&version=6.2.12.1017 was blocked due to mime type mismatch
Chrome:
Resource interpreted as Script but transferred with MIME type text/plain: "http://xxx/Telerik.ReportViewer.axd?name=Resources.ReportViewer.js&optype=Resource&version=6.2.12.1017".
SCRIPT5009: 'ReportViewer' is undefined
I have been through the the help topic located at http://www.telerik.com/community/forums/reporting/telerik-reporting/telerik-reportviewer-missing-in-iis-works-with-dev-webserver.aspx to no avail.
Here are the snippets from my web config file:
I have also added a MIME type for .axd in IIS and I have tried running Internet Explorer in compatibility mode with no luck.
Any help with this would be appreciated.
Thanks.
