I created CompositeAnnotation consisting of several elements (VerticalLineAnnotation).
I set visibility CompositeAnnotation to hidden but does not work.

How can I do it?

My case is a bit more complicated.

I’m working on the harmonic annotation. I created custom class base on CompositeAnnotation and I create dynamically vertical line annotations. I would like to show/hide my annotation.

I found myself solution. I use binding in code behind:

Binding binding = new Binding("IsHidden");
binding.Source = harmonicAnnotation;
annotation.SetBinding(VerticalLineAnnotation.IsHiddenProperty, binding);
