Label visibility from within an onclick event

See more:

XAML

Hello,

I was hoping maybe you could help me with a bit of code. I am
1. New to Object Oriented programming
2. Relatively new to Powershell
3. Struggling to get a good grasp on how to construct properly firing events that fire without a bad button lag. (interested in your background worker code bits)

I read your article and loved it as you seem to cover all these angles from a powershell WPF perspective

I was wondering why I cant seem to alter the visibility of a label from inside an event. Relevant code chunk is bolded MapPrinterButton Onclickevent


Other examples I've seen seem to be able to easily adjust the content of the label, but not its visibility, what am I missing?
