Hi redstar,

We are not aware of any problems with RadRichTextBox that could appear when the editor is ReadOnly. Like Petar mentioned previously, we would need some more information or a sample project in order to be able to reproduce the issue and provide you with better assistance.

All the best,
Iva

Hello redstar,

Unfortunately, I am unable to reproduce this issue in our environment. Could you please examine my test project and let me know if I have missed something? I can also change this ticket type to GeneralFeedback so that you can send us a project showing the problem best.  Thank you for your cooperation in advance.
