Tabitem可见性绑定WPF

Question

我正在尝试绑定标签项可见性，但它没有发生任何事情 这是我的代码

  

<TabItem Header="{Binding tabVisibility}">

并在我看来模态

public Visibility tabVisibility
        {
            get
            {
                return _visibility;
            }

            set
            {
                _visibility = value;
                NotifyPropertyChanged();
            }
        }

Answer 1

<TabItem Visibility="{Binding tabVisibility,Mode=TwoWay, UpdateSourceTrigger=PropertyChanged,RelativeSource={RelativeSource Mode=FindAncestor,AncestorType=TabControl}}">

Answer 2
