Disable/Lock Controls on Excel Worksheet

I am trying to disable/lock a lot of checkboxes(20) on an Excel worksheet if a certain condition is met.

Is there a controls property or something similar that will let me spin through all the checkboxes and lock?

Any help/guidance is appreciated.

One option is put your text boxes into an array and if the certain criteria is met run through the array and lock each text box.
