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.
Joe Glombek discusses how to integrate blocks into the Rich Text Editor (RTE) in Umbraco, replacing macros. Users can create "element" document types, add a Block button to the RTE toolbar, and configure settings for rendering. An example demonstrates rendering a phone number block with custom logic.
