error richtextbox and ribbon while typing

[Ceulemans]

Hello,

I am experimenting in WPF with a richtextbox and ribbon.
First, when I use a RibbonWindow I get this error message when I start typing in the richtextbox (see the error description below)

Secondly, I would like to use a Usercontrol instead of a RibbonWindow, can you give me an example

System.NullReferenceException

  HResult=0x80004003

  Message=Object reference not set to an instance of an object.

Hi Ceulemans,

We can reproduce the reported issue with “Exception is thrown on typing in SfRichTextBoxAdv with SfRichTextRibbon” and suspect this to be a defect. and we are working on creating a custom sample to maintain SfRichTextRibbon and SfRichTextBoxAdv under Usercontrol and update you with the custom sample along with validation details on 29^th December 2021.
