How to not show measure lines in PRV?

In Track View, here's what you do for audio clips:  View > Display > Vertical Grid Lines > check None.
 
I don't think there's an equivalent function for MIDI. You can hide only the higher-resolution grid lines, not the measures.

Tak - Maybe I didn't understand what you were saying, but I couldn't find a "Measure Lines" category; applying the default beat line color to Major Rules didn't seem to get rid of the measure lines, if that's what you meant. However if I changed the "Major Rules" color to white, although that doesn't totally get rid of the measure lines because the PRV still has the alternative light gray and white horizontal stripes for the black and white keys, the measure lines become pretty much invisible. So I think that would accomplish what the OP wants and maybe that's what you were describing?
 
On a related topic, I appreciate your giving me a heads-up about the color preference for measure lines because unlike the OP, I've always wanted to emphasize them more. So I made them magenta, and now I can really see those suckers! Thanks. I also found that changing the time ruler numbers color to yellow isn't as aesthetic, but they're a lot more readable.

I wasn't at the daw when I posted earlier so I said "measure lines" but the category I was talking about is actually "Major Rules." And IF what Randy wants to do is to have only beat lines (Beat Rules) and grid lines (Grid Rules) appear in the PRV (there's a high chance I misunderstand the original post), it is possible by making measure lines (Major Rules) look as if they disappeared by applying the color of Beat Rules to Major Rules.
 
Here's the result:

Kev said- If you don't need to ever display any measure lines in this project, then you could set the tempo to some very small arbitrary value, resulting in fewer lines spread wide apart.
Had I known it was going to be an issue this might be a solution (or at least help) but at this point it would alter the tempo of the parts I've already written and would no longer match the VO. 
The thing is guys, I don't really need ANY vertical lines (although I'll see if Tak's suggestion will help) for a project like this because the VO is dictating the tempo.
This particular project is kind of a guided meditation thing (but dealing with Qigong movements).
The following link is a similar project I did for the client...it'll give you a better idea as to why I don't want any vertical lines while writing in PRV.

Hahahaha...by god there ain't no vertical lines showing there Tak!
It would be nice to be able to see the horizontal lines but what exactly did you do in prefs to get this?
Thanks very much,
Randy

I think you'll find that if you make the Major Rules white they are essentially invisible.

You can insert a meter change of 99 beats per measure with a beat value of 1 (with the Project Menu). So if you disable Show Vertical Grid Lines in the PRV you'll only see one measure bar for every 99 measures.

...with a beat value of 1...

The minimum that you can set is 8 bpm.  I didn't discover this until after I posted my suggestion about setting a low value.

I checked those settings in Sonar X3 before posting and had no trouble inserting a meter change with a beat value of 1. It's even in the drop-down menu. Also, 8 bpm is a tempo not a meter setting.

My mistake.  I was was thinking about tempo rather than beat value.

I can't tell you how much I appreciate your efforts guys...lots of workarounds...thanks!

I can't speak for anyone else but on a personal note, you're very welcome and I hope you found something useful in this thread. I would also like to add that if you use the method I suggested, it won't have any effect on note placement, tempo, quantization, or the snap-to/by settings, and you can always make the PRV grid visible if you want to make a section fit into a steady beat.

It's a very clever workaround 

Nah, just basic music theory.
