Umbraco MVP and umBristol organiser working at Bump Digital
Joe Glombek discusses implementing a feature in Umbraco 17 to prevent the deletion of specific document types by using custom entity signs. The LockedDocumentFlagProvider class adds flags to locked documents, while the LockedDocumentComposer registers this functionality. This allows users to see locked status in the backoffice before attempting deletions.
