At any time, you can go to your grid settings (the gear icon on the grid), select the 'Show Grid Numbers NOW and lock grid' option and click Save Grid Settings. This will prevent any additions or changes to the grid and show the numbers along the horizontal and vertical axes. Note: This automatically happens when the event your grid is for begins. However, if your grid fills early or you know you will be getting no more squares filled, you can use this option.
