I added the NRichTextViewWithRibbonControl via XAML and VSStudio Designer.
How to make changes by code behind and C# ?
- Add custom things
- Add and remove Tab Pages

Please don't answer me with the standard documentation topic.
I know all of this. But the documentation explains only the doing for the code only version, but nothing about XAML and code behind.
And the code snippets only describe the handling for the NRichTextRibbonBuilder.
So why do you add NRichTextViewWithRibbonControl with full functionality, if it is not possible to change something to this?

I bought the Enterprise Edition and need your help.

Please give me a a sufficient example.
