Solution
It is possible to use the property nodes on LabVIEW NXG for version 2.0 and later. Go on the
Diagram and open the functions relative to
User Interface. Then, click on the
Panel Manipulation and drag the
Property Node on the diagram.
Now, you must create a reference of your object (a numeric control for example) by right-clicking on it and Create reference. Once the reference is created, it is possible to connect it to the property node and then the select the right property, like Disabled for example.
