Removing used channels from channel selection list on front end

[Silverfang-]

Hello everyone, I am currently trying to find a way to create a channel selection option on my front panel.

I have multiple cards on my PXIe system and I want to be able to manage channel selection from the front panel so that the dropdown only shows the channels that have not already selected. Screenshot attached.

AI has not been helpful with this and is giving me suggestions to use VIs that don't even exist. 

Need human help! Thanks in advance 🙂

Then you need to implement your own list of channels instead of using a DAQmxChannel control!

• Determine the available channels from your device and fill a ring control with those entries.
• You can disable entries, that are already selected.
• You should not use an array of rings as in an array all elements share the same properties…
