As far as I can see (LV 2013), there is a missing feature in LabVIEW, whereby, when you select multiple numeric controls, you cannot show/hide their increment/decrement buttons:
Here I have 3 DBL, 1 I32 and 1 enum, but this holds for any combination of numerics. If I right-click any of the selected controls, I have access to only two items under "Visible Items":
- Label
- Caption
Where is "Increment/Decrement" gone, considering that it is common to all these controls?
BUG? I could not find it mentioned elsewhere, but I would be surprised to be the first to have noticed it.
Solved! Go to Solution.

My understanding was that the actions that can be performed on multiple controls are not automatically generated based on shared options, but have to be specifically coded. I'm assuming this one simply wasn't.

Good find. I agree that the current behavior is undesirable. Here's what I found:
I think it comes down to a class issue. 'Numerics' do not have a property for "Increment/Decrement Visible". However, this property is available for 'Digital' and 'NamedNumeric', both of which are siblings under 'Numerics' (and these are what you were trying to alter at the same time). So as far as LabVIEW is concerned, it's 2 different properties for 2 different classes... which just happen to have the same name.

As I said, if I select two DBL controls, I still can only access two items under "Visible Items".
So I am not sure how to understand your analysis, as it would seem that nothing should prevent LV from pulling all common properties from those two identical controls...

Strange, I'm not seeing the same behavior. I only see the problem if at least one DBL and one Enum are selected. If it's just two DBL, I can see all the common properties. I'm in LV 2011 SP1.

Works as I said in LV 2013. Bug must have been introduced in the meantime...
Here's a video showing the problem.

BTW, are we talking about the same LV 2011, because on my SP1, if I do what I illustrate on the video above, the only menu item I get when right-clicking on two identical DBL numeric control is "Properties", which, when selected, opens up a window where I can indeed uncheck the "show increment/decrement buttons".
That is NOT what I am describing in my first post (and iluustrate in the video)! I am talking about a right-click menu item. The "Properties" window trick still works on LV 2013 (at least when the control types are identical).

LabVIEW 2012, no increment/decrement in Visible submenu of right click menu, either, for 2 identical numeric controls.
I believe tst's explanation.

X -
You are right. I read 'properties' and my mind went straight to the Properties dialog. Definitely seems like a bug.

Or a non-existing feature, most likely. I'll see whether this can be consolidated with an existing request on the Idea Exchange...some day.
