Powershell refresh CheckBox array from ComboBox - arrays

Question

With Powershell, I have a form with several tabs.
In the third tab, I make an array of numbers picked from Windows registry that I'll put in a ComboBox.
Then I make automatically several CheckBox by registry value names depending the ComboBox.
My problem is that I can't refresh/update the CheckBox when I change the text of the ComboBox. I tried ".Refresh()" like below and other things, but it doesn't work.
Here are my registry keys:

Answer 1

I don't think you're subscribing to the right event.
Have you looked at SelectedIndexChanged?
This will fire when a selection has changed and then you can look at the ComboBox's Index property to figure out which item changed. An index of negative one means no item in the combobox is selected.
The click event has nothing to do with selected items in a combobox.
