Hi,
I have a xamrichtexteditor and I am using some basic functionality, such as changing font or changing the font highlight colour
When I open the richtexteditor with text already in and I highlight the text colour or change font I get the following error:
Queue Empty.
Here is the stace trace:

Any ideas?
Thanks, Grant
Hi Grant,
How are you highlighting the text colour or changing the font? Are you doing this after the XamRichTextEditor has displayed on the screen with the text? Or are you doing this programmatically as soon as the editor finishes loading? Can you share some of your code that does this highlighting?
I'm using the build in ig commands to do this like so:
<Button Height="22" Margin="2,0,0,0" ToolTip="Toggle Bold"> <Button.Content> <Image Source="../Resources/FontBold_16x16.png" /> </Button.Content> <ig:Commanding.Command> <igPrim:RichTextEditorCommandSource EventName="Click" CommandType="ToggleBoldFormatting" /> </ig:Commanding.Command> </Button>
It is all functionality not just the font colour changing
I wasn't able to produce an exception using that code. I loaded up a XamRichTextEditor which already had text inside of it and when I click the button there is no exception. Though I have seen the message, "GetCaretLayoutFromDocumentOffset, document offset: 0 not foundCaretLayoutInfo not available!", before. What is the exact version number of the Infragistics assemblies that you are using?
Edit: The full version number. It would look something like this: 15.1.20151.****
I am also seeing the message "GetCaretLayoutFromDocumentOffset..." in the debug console of VS, but with no error or exception.
The exact message is "GetCaretLayoutFromDocumentOffset, document offset: 2697 > length: 2657" (the offset varies). What does it mean ? Is this a warning of a potentialy dangerous operation i'm doing one way and should be doing another way or is it just debug info ?
I'm using the 15.1.20151.255 version of the WPF Infragistics framework.
Do you still need assistance on this matter?
