PDF not showing as export option in Web Report Viewer

[Marc]

It shows on our dev server but not when hosted at a Rackspace Cloud Site. We do see CSV, TIFF, RTF and Web Archive as options. Are there Adobe components needed on the server? Our dev server has Adobe Acrobat installed. I see in the documentaton an entry "Configuring Telerik Reporting Config Section". Our dev server does not have <Render> entries in the web.config and PDF does appear as an option. I don't see in the documentation under what conditions you would need <Render> entries in the web.config. Any help would be appreciated.

Thanks,
Marc Borgo

Hello Marc,

Your web application is most likely running in Medium Trust, and as described in the referenced article, those formats would be automatically disabled, because they do not work under medium trust.

Best wishes,

Our hosting provider is running in a "Modified Medium Trust" setup. They provided the config file which has exceptions to regular Medium Trust. Below is this file. Could you provide exactly what is causing the PDF conversion to require Medium Trust? We might be able to get them to make an exception for the needed module.

If we cannot get this to work I was thinking of exporting to TIF and then creating a PDF file myself.

Thanks for any help,
Marc

Hello Marc,

As noted in the Medium Trust Support help article that my colleague referenced in the previous post: The PDF rendering extension requires UnmanagedCode permission to operate.

Best wishes,

Sorry for one last entry before giving up all hope,

They had given me hope by saying they use a modified Medium Trust config file and there were exceptions made. I was hoping your module was using a 3rd party library or .NET Framework module that could be referenced in their tweaked Medium Trust config file that would allow your module to run in their Medium Trust environment. From your last post, I assume that is not an option. Thanks for your quick response and great support.

Marc
