disabling control through subvi

[festo]

I want to be able to enable/disable controls through a subVi. Currently I am able to do this in an event structure. I select an option on a control on the main panel which causes an event to activate the subVi and enable/disable controls on main panel accordingly. My issue has to do with initially opening the main panel - the subVi is called but the controls on the main panel are not enabled/disabled.

The easiest way to do this is to use a control reference. By right clicking on the control you can select create>>reference. Pass this reference into your subvi and under the application control pallette select a property node. You can then select the disable property after you have connected the reference. check out my example. hope this helps.
