When a RadRichTextBox control is added as a child to RadCalendar, the Space and Enter key input is stolen by the calendar. Workaround is available here: http://www.telerik.com/community/forums/getting-visible-dates-from-radcalendar
Hello,
This behavior was first reported more than 10 years ago, and we haven’t seen significant demand or follow-up from the community since then. As a result, we currently plan to prioritize improvements with broader impact and higher demand.
I marked this thread as "Declined". If this limitation is still affecting your scenario, please share additional context or use cases.
Regards,
