RadRichTextBox Print Error with Header Section in Xaml format

[Raaj]

I get the following when I try to print using a RadRichTextBox control using XAML format with a Header section.
The app is using Silverlight 5 and Telerik 2011.3.1406.1050 version. 

In the app we using the ReadOnlyEditor as a Print Preview before the actual printing. The XAML fed to this control is generated by another screen with a RadRichTextBox.
The is error raised only if there is a Header section and the whole screen turns white. There is no error if there is no Header.
I have a sample project which can reproduce this error. Is there a way I can upload a rar file?
Also issue I have heard from my testers that sometime with editing the header section like adding/removing image it raises a Silverlight error. Though I am not able to reproduction it but thought it could be related to the first issue.

 Please let me know if there is any particular setting that I am missing.

Thank you,
Raaj

Hi Raaj,

There was indeed a bug with the native printing when the document contains headers or footers.

We have fixed this issue in the latest 2012 Q1 release - 2012.1.215, so if you upgrade, the problem should be solved. With the version you are using, the only workaround to prevent the crash of the application would be to remove the headers and footers from the document. There is no way to print the headers and footers though.

All the best,
