Exchange the Columns elements of a ListView

P1
P2

Hi Community,
I generated 2 columns elements in a ListView under Labels A and B (as picture shown), how can I exchange these 2 columns elements when pressed a button?
Thanks!

Make another list.

or create a starter list with all your values, then a procedure or two to generate the lists required.

Something like this, but you could do this in one procedure with the right parameters:

Thank you very much! And I will try your method. :pray: :smile:
