Is it possible to do a dual listbox custom dialog with wixtoolset using a custom action?
I'm essentially trying to do this: https://www.advancedinstaller.com/user-guide/tutorial-combobox-listbox.html#combolist-scenario1
Half of the solution is here: https://www.firegiant.com/wix/tutorial/standard-libraries/custom-actions-and-user-interface/
I got my first listbox populated using WcaAddTempRecord (wcautil from wixtoolset sdk). The problem is that I can't get the second listbox to show the added data when "moving" a listitem to the second listbox. I even tried to publish the NewDialog event to show a second dialog with the same dual listbox controls, which seems to be the workaround proposed on various posts on this subject. No success there either; I just can't get the second listbox to show its content.
I did look at wixtoolset sources for an WcaAddTempRecord on a listbox but the only usage was commented out.
Any pointers?
