Does all code for tabs in a tab control have to all go in the toplevel block diagram?

Does the code for each tab in a tab control all have to go on the one toplevel block diagram, or can code for each tab be sectioned off somehow?  I want to try and keep my toplevel block diagram as simple as possible.

Thanks

You could 'section' off each code in a tab control in a separate subVI. You could use references to update the front panel controls placed in each tab. I would suggest bundling all controls for a particular subVI and passing that off into the subVI. Have a look at the following link:

How Can I Update the Front Panel of a Calling VI From a SubVI?

Thanks for the reply.  With the reference method does the control on the tab still have to be in the main diagram (as opposed to being in the subvi).  Each of my tabs will have 24 controls and I have 6 tabs so wanted to minimize the large no. of controls appearing on the main diagram.

Yes, that is true. The other method that I would suggest is to use the subpanel contro. For example, you can use a subpanel control to design a user interface that behaves like a wizard. Add the Back and Next buttons to the front panel of the top-level VI and use a subpanel control to load different front panels for each step of the wizard. Have a look at the following:

Loading a Front Panel in a Subpanel Control

And, be sure to open Example Finder and search for subpanels.
