A similar behavior could be observed when RadRichTextBox is placed inside a container which measures its children with Infinity
. Can you please ensure that the container sets a size to RadRichTextBox? If this is not the cause of the issue you are observing, can you please share more details on your setup?
As to the theme, we are unaware of a similar behavior and I will need more information on this matter as well. Can you share an image showing the result you are getting? What is the expected one?
Please, note that the public forums allow you attaching only images. If you would like, you could open a ticket
through our ticketing system where you can attach .zip files.
