WebViewer Export to RTF throws exception - Attempt by security transparent method

[Frank]

Hi,

I have just noticed an exception when trying to export a report to RTF from the WebViewer control which now throws the following error:

Attempt by security transparent method
'Telerik.Reporting.Rtf.ImageUtils.GetMetafileBounds(System.Drawing.SizeF)' to
call native code through method
'Telerik.Reporting.Rtf.GdiNativeMethods.GetDeviceCaps(IntPtr, Int32)' failed.
 Methods must be security critical or security safe-critical to call
native code.

The exception occurs on my local Dev Environment (Windows 8 with IIS 8) and our Staging server (Windows Server 2012 R2 with IIS 8.5) and is using .Net 4.5

Any ideas why this is occurring?

Hello Frank,

There was such issue with RTF export in previous version. The issue is fixed as of Telerik Reporting Q3 2013 SP1 version 7.2.14.127. Please download and test it.

If the issue still appears, we will appreciate it if you open a support ticket and send us a sample project that reproduces the problem.
