Hi, In the attached VI, when a boolean from BooleanArray is True, that row is highlighted. When the clear button is pressed, all highlighted rows are cleared. The next time the array changes (triggered by the event structure), the Trued booleans are highlighted again. I would like to be able to highlight only the boolean that were not True before the clear button was pressed. In other words, I only want to highlight new booleans. I think of shift registers, but I am not sure how to implement that in here. Thank you for your help.

Shift register is correct. Every time the Clear button value change event is triggered True, pull the current highlighted cells in the form of an array and write them to a shift register. Every other event case should just pass this array through without changing it. The event when BooleanArray changes should pull in the array of cleared rows and not highlight those. Make sure that if you clear again after already clearing, you append the new cleared values. You will also need to take in to account when a previously cleared value is changed... so that would require you to edit the cleared values and remove one if it changes value... Hooovahh's second idea is what you want. See attached.
