Disable Indices of System Ring programmatically

[goodnaysayer]

I am trying to enable/disable indices of a system ring during runtime on checkbox events.

I have included a sample VI with the following:

Front Panel
A "Tools Palette" with 2 button controls with a checkbox and a string indicator corresponding to each button control. 

BD

On a checkbox value change event

-The visibility of the corresponding button control is set to the value of the checkbox. 
-The Name of the currently shown item in the ring control is applied to the corresponding string indicator.
-The Value of the currently shown item in the ring control is stored as an ID for the button control. 

-If the checkbox is now true, the index of the currently shown item in the ring control should be disabled.

-If the checkbox is now false, the index of the currently shown item in the ring control should be enabled.
/*The enabling/disabling is done by adding/deleting elements from the DisabledItems[] property.*/

The process seems correct, however, I have only been working with LabView since February so I may be doing something horribly wrong.
Transitioning from a C background has been... interesting. 

(Also, I am using Local Variables because I don't know how else to work this problem,

so, unless you can explain how to accomplish the same thing without them, please ignore my LabView  no-no)

Hi goodnaysayer,

Welcome to the graphical programming environment. From your sample VI, you seem to have a good handle on the many features available in LabVIEW. For disabling indices of a Ring, the Disabled Items[] property node would be the tool to do that.

As in any programming environment, there may be multiple ways to solve a problem. As long as your code meets your requirements, you should be fine. In this instance, an alternative to using local variables could be using shift registers.
