     I'm using 2009 Q1.  This is a .net 3.5 web application.  I tried reinstalling Telerik Reporting and I still get the error.  Any ideas?

    Hello Jon,

    It would be best if you attach a sample web site/app that shows the error at hand in a support ticket, as we've not been reported with this problem before. What is the browser and version that this happens on and does it happen on other browsers as well? Any additional information that you could provide would be highly appreciated.

    All the best,
    the Telerik team

    A lead developer at my company helped me get this resolved using fiddler.  It was due to security settings in my application.  Since I am testing my application, I was allowing all users to access the page that the report viewer is on to avoid having to login everytime, but not for the report viewer, which apparently is viewed as a page on it's on.  Once we turned security off in the web config, I was able to view the report.

    <location path="Telerik.ReportViewer.axd">
                 <allow users="*"/>

    Per the post above about security issues, I added this to my web.config file in the <configuration> tag and all worked as it should.  Thanks for sharing the fix above because none of the other suggested fixes were appropriate for correcting the issue in our project and I was about to start tearing out my hair in frustration.

    Hello Akhil,

    without more details it is hard to determine the cause of the issue in your case. Please take a look at your support ticket regarding the same question and update it with the requested details.


    Have you tried the new visualization options in Telerik Reporting Q2 2013? You can get them from your account.
