When using AllActiveRegion in desktop application

For an accordion region adapter

What would be a good way to get notification when the view got focus

Meaning user select the accordion item of that view?

Thanks in advance

Since the AllActiveRegion keeps all its views as active, its ActiveViews collection should not change when one of your views inside the accordion gets focus, so in this case it seems that it won't be useful to hook to that event.

Therefore, (assuming you're referring to the WPF Toolkit's accordion control), you could hook to its SelectionChanged event, which, based on my understanding, should be raised each time you switch the "active" element inside the accordion.

I hope you find this helpful.
