Problem with rendering report in published version

[Marc]

Hello.

I want to save a report as an pdf-document. Herefore I use following code:

try
{
    ReportProcessor reportProcessor = new ReportProcessor();
    RenderingResult result = reportProcessor.RenderReport("PDF", report, null);

    using (FileStream fs = new FileStream(fileName, FileMode.Create))
    {
        fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);
    }
}
catch (Exception ex)
{
    return false;
}

This actually works on the working machine debugged with VS2010. But when I want to use this as published version on the server the following error occurs (on rendering the report):

MESSAGE:

May you have a solution or some hints for me what errors could have this exception in consequence?

Thanks.

Hello Uwe Frigger,

The error you've encountered could be caused by two things:

1. You have a rendering extension setting in the Telerik Reporting config section in your application config file and it is not valid. More information on configuring the rendering extensions is available in the following articles:
   • Configuring Telerik Reporting Config Section
   • Device Information Settings
2. You have not deployed the application correctly. Please refer to the Deploying Applications using Telerik Reporting help section for step by step instructions.

Best wishes,
Steve
the Telerik team

Thank you very much for your help.
