Cluster of Boolean Controls Problem

[Garord]

Hello All,

I was wondering what would be the best way to go about implementing a radio-button type architecture for a cluster of boolean controls.

My current problem: I have a cluster of boolean controls (12 of them) all sorted in rows of 3. For each control on each row, I would like to disable and gray out the two other controls that are not pressed. This would be similar to radio buttons; however, I would also like to be able to leave all the buttons unpressed (all false). 

I'm not exactly sure if the radio buttons could apply in this situation, but I have tried to tinker around using a case structure with property nodes without much luck. I was able to get to a point where I could pull out the labels of the booleans into a case structure. I'm not sure if this would be the best way to go about it, so I'd really appreciate any help. I've attached a picture of the VI down below 

Thank you very much

Use an event structure.  Whenever something in the cluster changes, iterate though all the other controls to disable and grey them, and set them to false when a button is set to true.

When a button is set to false, enable all controls.

RavensFan -- Thank you for the speedy reply.

So from my understanding you are suggesting making an event structure for the entire cluster and triggering an event based off a value change inside of the cluster, correct? So essentially it will have one event, and I would have to find the changed element so that I could disable and gray the other two controls on the row. 

I wonder if I could create an event structure and add event cases for each boolean in the cluster separately. That way, I could immediately set the condition of the other two controls easily by wiring the new value to a case structure and subsequently using property nodes. May be a bit tedious, but I wouldn't have to go through the extra logic or loops...

Is this what you are trying to do?

Exactly.

You create multiple events.  But once you get beyond a couple, it is worth the effort of doing loops and would be more easily expandable to X number of controls.  I, myself, would go straight to a loop method and a single event.

RavensFan -- Thank you for your help, I was able to implement one with the functionality I wanted.

paul_cardinale -- I am unfortunately not able to open your control as I am using LabVIEW 2017 and I believe yours has been saved in LabVIEW 2018. If you don't mind saving for a previous version, I would be more than happy to take a look. Thanks for sending that over.
