I have not touched C# in years and low and behold it has drastically changed.
I am working on a small project and I am looking for help for the following scenario:

the following listbox is bound to an XML file that is included into the project.

how would I go about to load data from a different XML file into the same box?

For your information, there will be 5 listboxes that depending on the user's choice load from different data files

I was thinking initially of creating 15 listboxes and hiding/showing them depending on the user's choice, but that seems to be a waste of resources.
So instead i want to re-utilize the same boxes and populate from different lists.

All is coded in C# XAML (which is new to me) and should run in a WPF environment.

I appreciate your help
