Question

I have defined a default binding in my style.

For example I have configured the visibility binding of my button so that it must not be visible if the relative command can not execute.

This is my default binding behavior.

Apart from my default behavior, every view can customize the buttons it uses with another visibility binding.

I want to combine the two bindings so that if any of two say “it’s not visible” it will be not visible!

In other words, is it possibile to create a binding behavior hierarchy? Thanks!

No, sorry, not possible in XAML.

You CAN do this combination in code, though. You can write a BindingConverter for this.
