I'm using a RadRichTextBox as a pure preview for printing. IsReadOnly is
set to True, but you can still enter header edit mode.
This means that when the document is first shown, the header is grayed out.
And when you double click the header, entering edit mode, the
rest of the content is grayed out.
This will lead to a kind of "false preview" of the document, as the colors will not match the final print.
Is there any way to enter a "true" read only/print preview state?
