Hello,
since updating to Q2 2011 I am not able to print a simple RadDocument out of a RadRichTextBox.

We are using version 2011.2.712.1040.

My XAML:
<StackPanel>
  <Button Name="btnPrint" Content="Print" Click="btnPrint_Click" />
  <telerik:RadRichTextBox Name="richTextBox" Width="200" Height="200" />
</StackPanel>
My Code-Behind  
private void btnPrint_Click(object sender, RoutedEventArgs e)
{
  richTextBox.Document = new RadDocument();
  richTextBox.Print("Test", PrintMode.Native);
}

I get the following exception after clicking the print button:

If I use the Q1 libraries (2011.1.315.1040) everything is working fine.

What am I doing wrong here?

Sorry, I didn't see that there is already another thread with this problem (http://www.telerik.com/community/forums/silverlight/richtextbox/printing-and-printing-in-oob.aspx). Maybe you could merge the two?

Hi Thomas,

Unfortunately there is a bug with Silverlight printing in the Q2 official release (2011.2 712), which was introduced at a very late stage of development and passed in the final build. The good news is that we fixed it immediately in a subsequent build just a bit after that. You can download a hotfix from the Latest Internal Build from your account (Internal Builds Download section).
