Locking Schedule Dates

To prevent unintentional changes to the horizontal positions of objects on the canvas, the Date Lock mode can be used. Date Lock mode prevents any mouse-based changes to horizontal positions of objects on the canvas; however, if need be, dates can still be changed via property boxes, and all objects can still be moved to different grids.


  1. Click the down arrow to the right of the Change Display Mode  icon from the toolbar.
  2. Choose Date Lock from the menu.

NOTE: Pressing the ALT key while moving an object will temporarily enable Date Lock.
