Hi,

I am using Telerik Reporting Q3 2010 to export Telerik Reports into PDFs.  Since the new update of Firefox to include their own PDF viewer all PDFs created by the Telerik Export is resulting of a black screen in Firefox.  Every other PDFs I try to open that are not created by Telerik are opening fine in the browser.

Here is the code I am using :

      ReportProcessor reportProcessor = new ReportProcessor();
      RenderingResult result = reportProcessor.RenderReport("PDF", myReport, null);
      string path = savePath + reportName + ".pdf";
     
      FileStream fs = new FileStream(path, FileMode.Create);
      fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);
      fs.Flush();
      fs.Close();

Attached is the result in Firefox.

Is the new version of Telerik creating PDF that are readable by Firefox?  I tried downloading the demo and using the upgrade wizard but the upgrade wizard is not upgrading anything, or almost nothing.  I get 150+ errors like cannot convert group[] to ...  or cannot convert filter[] to ...   And they are all in the designer files that are generated by Telerik.  So not a solution at all since I have a tons of reports.

Any kind of help would be fine, I need those PDFs to display in Firefox.

Thanks,

Edit, forgot to attach the image

I don't experience the problem, PDFs generated with the latest release are displayed OK with the PDF.JS viewer http://mozilla.github.com/pdf.js/web/viewer.html

Hi,

I figured the latest release would be fine.  But is it known by Telerik that the 2010 Q3 release is creating PDFs that are not readable by the new Firefox release?  Or maybe there is another way to convert a Telerik Report to a PDF instead of the one I have linked.

It is not an option to buy the new 2013 Q1 Release because I tried the demo and the upgrade wizard is not converting anything.  Meaning I would have to redo about 80 reports one by one.  Not a solution at all.

I wish Telerik or someone would give me an alternative to convert a report to PDF by code.  Maybe there is a parameter / setting that I am not setting before converting it.. Hard to tell.

But thanks for your answer,

Usually I upgrade the designer obsolete code by making any change to the report in the designer move an item or turn on/off snap grid. This only work prior the obsolete types are removed.

After the wizard upgrade, I cannot even open the reports.  It displays a bunch of errors.

The obsolete properties were removed:
http://www.telerik.com/products/reporting/whats-new/release-history/q1-2013-version-7-0-13-220.aspx
The easiest way to fix them is to install a previous version(e.g. 2012 Q3) and after that fix all the warnings related to obsolete properties. After that install the latest telerik reporting version and everything should be fine.
