C＃：Caliburn Micro：如何使用数据绑定控制WPF Button的属性？

问题描述

当用户按下某个按钮时，我希望该按钮消失并由“确认”按钮代替。以下代码是我认为会使按钮消失的代码，但是当我单击按钮时，什么也没有发生。使用Caliburn Micro约定将DeleteButton（）方法正确地连接到XAML。如何从viewmodel控制按钮的可见性或任何其他属性？谢谢。

XAML：

<Button x:Name="DeleteButton" Visibility="{Binding DeleteButtonVisibility}"/>

viewmodel：

    bool _deleteButtonVisibility = true;

    public bool DeleteButtonVisibility
    {
        get { return _deleteButtonVisibility; }
        set
        {
            _deleteButtonVisibility = value;
            NotifyOfPropertyChange(() => DeleteButtonVisibility);
        }
    }

    public void DeleteButton()
    {
        DeleteButtonVisibility = false;
    }

解决方法

可见性不是布尔值，而是System.Windows.Visibility

尝试一下：

    Visibility _deleteButtonVisibility = Visibility.Visible;

    public Visibility DeleteButtonVisibility
    {
        get { return _deleteButtonVisibility; }
        set
        {
            _deleteButtonVisibility = value;
            NotifyOfPropertyChange(() => DeleteButtonVisibility);
        }
    }

    public void DeleteButton()
    {
        DeleteButtonVisibility = Visibility.Collapsed;
    }
