Is it possible to change the properties of a front panel indicator such as background color or to change from enabled to disabled-grayed out programatically in response to limit conditions or a time-out?

I am a neubie to LabVIEW. I have been programming this week only (5 days). I also was trying to modify the 'Disabled' property of a digital numeric indicator. I did know how to create a property node and set it to 1, Disabled, but the indicator continues to change its value after being disabled. Is this the expected behaviour? I am just trying to freeze a reading from an analog input once a digital input goes high.
"Disabled" means that the control/indicator will not respond to a user operation. However, the displayed data can still change. What you want to do can be easily achieved using a case structure : wire your boolean to the case input, and put your indicator in the "True" case condition. That way, it will be updated only when the digital input is set to true.
That is expected behavior. The disabled property does not stop the program from writing to an indicator. It only prevents a user from modifying it. To do what you want, use a shift register/feeback node. The attached picture uses a random number generator to simulate your analog input and a Boolean to simulate the digital input.
What did you do to create the arrow pointing back to the data input of the Select function? I've looked through some of the function categories where I think it would be, but I cant seem to find it.
