This template (and its associated code templates) has been deprecated, and is now replaced by the RTF Text Control template.
The CanUndoRTF code template checks the RTF control to see if there is data in the undo buffer. A TRUE value is returned if an undo can be done. A FALSE value is returned if there is no undo data in the buffer. This template calls the Undo method.
