"Select All" button implementation in tree control

[cha@bellflight.com]

Attached is my LabVIEW 2019 SP1 (64-bit) tree control application VI. Instead of using Ctrl or Shift key to select hundreds of Item Codes to either add or remove, I just click on the "Select All" button, then all Item Codes are highlighted in blue, ready for addition or removal.

How do I implement this button?

You could implement this with the two tree properties "All Tags" and "Value". Both are type String[] so you can just read the All Tags property and feed the output value into the Value property which will select everything (for a tree the value represents what is selected).

Thanks for your help, Jacobson,

Attached is the solution.

I made a set of code for doing multi tree and listbox selection with the checkbox glyph here.

In it I have a right click menu for Select All/Select None, and Invert Selection.
