A very flexible way of managing lots of control and indicators on a User Interface is to create a cluster of control references for all control and indicators. This can then be used in the subsequent User Interface code to set properties, get values, set values.
I found a great feature today that saves lots of time creating control references for front panel controls & indicators. Simply drag & select multiple control/indicators on the block diagram, right click and select Create > Reference.
LabVIEW then creates a control reference for each selected item. Consequently, this saves you lots of time over creating each reference individually.
