I'm using the SyntaxEditor ShowPrintDialog method which is doing a very nice job. WPF Controls 2013.2 build 0591.
One item that is a bit of a bother is that the print dialog is not modal so the user is able to interact with the editor while the dialog is displayed.
I also tried the ShowPrintPreviewDialog which turns out to be modal but when the print button in that dialog is clicked the print dialog comes up and it is not modal.
Is there a feature or setting I am missing or other suggestion?
