Wpf- Is there a worth while way to add richtextbox capabilities (Bold, Italics, Underline, Strike-Through) to a control which inherits from textbox?

Question

I am writing a text editor and had planned on using the richtextbox control however, the richtextbox's performance is abysmal. On even small documents the wpf richtextbox lags if you hold a key down. I do not need all of the features of the wpf richtextbox, but I do need rtf support. How can I implement this?

Answer 1

If you need RTF support, you're best off just using RichTextBox. RichTextBox's slower performance mainly comes from supporting RTF, which is not trivial.

Answer 2

The wpf richtextbox understand FlowDocuments Winforms richtextbox not.

Maybe this helps you in general using wpf`s richtextbox:
