c# - 获取已检查的事件数据绑定(bind) wpf

Question

我在 wpf 中创建了一个文本框、一个密码框和一个切换按钮。我需要，当我选中按钮时，密码是可见的，当取消选中按钮时，字符显示为项目符号。我的问题是，当我运行应用程序时，该按钮未被选中(这意味着隐藏密码)，但密码仍然显示。就在我检查按钮之后，一切都按我的意愿进行。我怎样才能从头开始绑定(bind)？不仅在我检查之后

XML代码:

   <ToggleButton  Name="toggle1" Height="40" Padding="0" Width="56" Canvas.Left="131" Canvas.Top="0" BorderBrush="{x:Null}" IsChecked="{Binding ShowPassword}">

代码:

public bool IsPasswordVisible
    {
        get { return _IsPasswordVisible; }
        set
        {
            if (_IsPasswordVisible == value)
                return;
            _IsPasswordVisible = value;
            if(IsPasswordVisible)
            {
                passwordBox1.Visibility = System.Windows.Visibility.Collapsed;
                textbox1.Visibility = System.Windows.Visibility.Visible;
                textbox1.EditValue = passwordBoxEdit1.Password;
            }else{
                passwordBox1.Visibility = System.Windows.Visibility.Visible;
                textbox1.Visibility = System.Windows.Visibility.Collapsed;
                passwordBox1.Password = textEdit1.Text;
            }
            if (PropertyChanged != null)
                PropertyChanged(this, new PropertyChangedEventArgs("ShowPassword"));
        }
    }       

    public MainWindow()
    {
        InitializeComponent();

        this.DataContext = this;

    }

    public event PropertyChangedEventHandler PropertyChanged;

    #region OnPropertyChanged
    /// <summary>
    /// Triggers the PropertyChanged event.
    /// </summary>
    protected void OnPropertyChanged(string propertyName)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
            handler(this, new PropertyChangedEventArgs(propertyName));
    }
    #endregion

在看到数据上下文后将 IsPasswordVisible 设置为 false

this.DataContext = this;
IsPasswordVisible = false;

从 IsPasswordVisible setter 中删除以下代码

if (_IsPasswordVisible == value)
                return;
