Reoports don't render in IE10 but they do in Chrome

[Mark]

Hi I am just testing out the ASP.net Reportviewer on IE10 (in SharePoint 2013). The report never completes (we can see the spinning animation for ever). Is this supported ? 

Our version of the reports is 6.2.12.1017

I am having the same issue, and the linked thread/suggestion is not applicable for me - I do not have the nosniff header.  I experience this on my Win8 development environment (using the asp.net dev server) as well as on a Win2008 IIS Server.  The site works fine in IE9, Chrome and Firefox, but IE10 in Win8 never displays.

Hi Eric,

We haven't been reported with such a problem up until now and we'll need some guidance in order to track down the issue.
Please, first try to open our online examples with IE10. In case that you're not able to see them correctly disable all IE plugins and try again.
If our online examples work correctly on your side in IE10, please open a support ticket and send us a report definition(running project will be best), which could be used to reproduce the problem locally.
Any additional information you find relevant will be appreciated (for e.g. screenshots of the report in IE10, machine configuration, .NET version used, VS version etc.).

All the best,

I did hit the nosniff header issue and managed to get around it with an httpmodule. Read about it in my blog post titled : The IE10 nosniff issue in SharePoint 2013.

Please let me know when this is fixed so I can remove my workaround.

Hi Mark,

The "nosniff" issue is already fixed. You can download the Telerik Reporting latest version and everything should be fine.
