ABSTRACT:
An editing environment is disclosed having both a design and code views, each with its own undo/redo stacks. The editing environment includes logic to form an object that encapsulates the edits and changes made during a code view editing session. The object is associated or pointed to an element in the design view undo/redo stack. When the editing environment receives an undo/redo command in which a code view edit block is to be undone, the design view takes the specific object, which is then translated back into the proper format for code view execution. The code view then executes the undo/redo entries and returns any remaining code view edits that were not undone or redone, to the design view to place back into a code view edit block in either of the design view undo/redo stacks, along with the new related object.
