While examinig the Features.2005 example, I was stymied as to how the count property was set. There did not appear to be any way to set it from the form designer. After debugging the app and commenting out the deubggerstepthrough in MainForm.Designer.vb to allow stepping thru the form generation, I found where it happens. There is a line
Me.layoutNumericEditArray.ScaleMode = NationalInstruments.UI.ControlArrayScaleMode.CreateFixedMode(3)
that does it. Then I found a Scalemode property that was set to Fixed:3.
There is essentially no documentation on how to use the new SwitchArrays and LEDArrays in apps. The starting point appears to be the parent class ControlArray<TControl> documentation. The example is not hyperlinked in the online help either. That would be nice.
I'm just passing along this as information to other users. Hopefully the documentation will catch up.
