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:

</location>

<location path="Telerik.Web.UI.WebResource.axd">

<system.web>

<authorization>

<allow users="*" />

</authorization>

</system.web>

</location>

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.

Hi Adam,

If the report is loaded correctly in Firefox and Chrome, most likely the problem is with Internet Explorer DOM object. Are you setting height to the viewer in percentage and if so, did you set height to the whole DOM tree (see How do I set 100% height to the Web Report Viewer)? You can very easily check that by starting IE's Developer Tools and inspect the viewer report area height.

Hi,

I have checked this, but unfortunately makes no difference. Here is my code:

<html xmlns="http://www.w3.org/1999/xhtml" id="html">

<head runat="server">

<style type="text/css">

html#html, body#body, form#form1, div#content

{

height: 100%;

}

</style>

</head>

<body id="body" style="margin:0px; padding: 0px;">

<form id="form1" runat="server">

<div id="content">

<telerik:ReportViewer ID="MainReportViewer" runat="server" Height="100%" Width="100%"/>

</div>

</form>

</body>

</html>

Hi Adam,

Do you observe the same problem if you set a fixed height in pixels? The problem is not related to the report generation on the server as otherwise it would not be rendered in any browser, so it has to be an issue with the browser itself. Can you provide us with screenshots of the problematic page with IE's Developer Tools opened and showing the height of the report area?

Hi Adam,

We took the time to setup Sharepoint 2013 server and test on our own. We were able to reproduce the problem and identified the culprit being a fabricated MS response header: nosniff. More information about it can be found in this MSDN article. Removing it from IIS Manager -> HTTP Response Header would resolve the problem and the viewer and report would be loaded properly.

Still, we would make a change on our end to register our scripts with a more appropriate mime type. This fix would be for the Q1 2013 release in February.

Your Telerik points have been updated for bringing this to our attention. Let us know how it goes.

Kind regards,
Steve

I have version 7.0.13.220. I do not see an option to download the internal build .228. On the side it says: "If you don't see internal builds, you have to download the lastest official release first" -- which I believe I have (.220)...

Working with .220, I have tried removing the nosniff header and adding document mode to IE=edge. Neither of these made a difference. Also, this only occurs with 3 of our 10 reports. They work fine in our development and test environments (SP 2013) and also in an SP 2010 environment. I check our logging, and the data is retrieved -- but the reports just spins forever (never times out or anything)

When I open the reports in chrome, I actually get a 403 FORBIDDEN message in the report area.

Please help!
