I apologize for misleading you.
If I understand correctly, you have tried printing by calling the PrintPreview()
method of RadRichTextBox and clicking the button in the shown window. What I meant by print preview was not that, since the PrintPreview()
method executes the same logic as the one executed when printing using HTML PrintMode. That said, it is not possible to use this print preview and Native mode with this approach.
My idea was to make sure your document is ready by, for example, showing it in a RadRichTextBox which is with limited editing capacities or read only.
When it comes to the documentation, the link you found is the one pointing to our online help. We constantly try to improve it and your feedback is valuable to us. In regard to printing - we've already added an article explaining the best approach for building a document in code-behind and printing it. It will be included in the next documentation version later today in the HowTo section. If you have any other suggestions please share them with us here or send us your feedback at firstname.lastname@example.org. Thank you!
I hope this makes things clearer. Please, get back to us if you have additional comments or questions.
