graying out selections

[csmrunman]

Is there a way, using property nodes, to get something to gray out on the front panel based on a user selection? For example, I want to have a radio button, or something similar, to display what type of experimental method was chosen from a drop-down menu. The other possible selections on the radio display would be grayed out, if not selected.

thanks in advance

yes use the disabled property

Set disable property to disable and gray (value 2).

I'm assuming you know about event structures?

Were you able to implement these suggestions? If you are having trouble, post it.

Thanks,

I know how to disable and gray an item, like mentioned above, but that isn't what I'm looking to do. That option appears to have things permanently in that state, once selected. I wanted to disable and gray items out, only after another option had been selected.

As for event structures, I get confused as to what the differences are between it and case structures. I have no experience with event structures, so I see them in LabVIEW examples, but I get lost trying to figure out the setup. 

This would be a nice little add-on to my code and isn't the focus right now. So, I have pushed it to the side for the time being.

This case in the event structure fires only when the disable boolean is pressed.

If you want a specific radio option, rather than the whole bank of radio buttons, you need to do something like this

I was attempting to re-create both of those event structures, so I can get a better grasp of the coding and process, but ran into some issues. How, in that first screenshot, did you get NewVal to turn green, for the boolean? I can't for the life of me find an option that allows me to turn that NewVal green, so that it outputs a boolean.

thanks

The event has to be linked to a boolean control.  In hte top of the event structure you see it's called Disable: Value change.  Disable is the name of the boolean that you press.  The VI I used to make the picture is attached in my previous post.  Give it a look.
