我创建了一个警告窗口来验证用户的删除操作,使用 Window.ShowDialog 并设置 DialogResult。一切正常,除了警告文本没有出现在中TextBlock,我不知道为什么。这是我的Window

<Window x:Class="RoVCo.Windows.VerifyWindow"
        ....
        WindowStyle="None" Padding="10" ResizeMode="NoResize">
        <StackPanel>
            <TextBlock Height="Auto" Text="{Binding TBText, Mode=OneWay}" Foreground="Yellow" TextWrapping="Wrap" />
            <StackPanel Orientation="Horizontal" HorizontalAlignment="Right" Margin="0,10,0,0">
                <Button Content="Cancel" Margin="10,0" Width="50" Click="CancelVerify" />
                <Button Content="OK" Width="50" Click="ConfirmVerify" />
            </StackPanel>
        </StackPanel>
</Window>

和班级:

public partial class VerifyWindow : Window
{
    public VerifyWindow(string content)
    {
        InitializeComponent();
        _text = content;
    }
    private string _text = "";
    public string TBText { get { return _text; } }

    private void CancelVerify(object sender, RoutedEventArgs e)
    {
        this.DialogResult = false;
        this.Close();
    }
    private void ConfirmVerify(object sender, RoutedEventArgs e)
    {
        this.DialogResult = true;
        this.Close();
    }
}

我这样称呼它:

var window = new RoVCo.Windows.VerifyWindow("Removing this skill will erase all DP spent on it from all levels. Continue?");
if (window.ShowDialog() == false) return;

如果它只是您在其中使用的单个属性,Dialog我认为使用 aDependancyProperty将是更好的选择,那么添加所有INotifyPropertyChanged逻辑

public partial class VerifyWindow : Window
{
    public VerifyWindow(string content)
    {
        InitializeComponent();
        TBText = content;
    }

    public static readonly DependencyProperty TBTextProperty =
        DependencyProperty.Register("TBText", typeof(string), typeof(VerifyWindow), new UIPropertyMetadata(string.Empty));

    public string TBText
    {
        get { return (string)GetValue(TBTextProperty); }
        set { SetValue(TBTextProperty, value); }
    }

    private void CancelVerify(object sender, RoutedEventArgs e)
    {
        this.DialogResult = false;
        this.Close();
    }
    private void ConfirmVerify(object sender, RoutedEventArgs e)
    {
        this.DialogResult = true;
        this.Close();
    }
}

为了使用绑定,您需要公开本地属性,并且需要通知属性或依赖属性。

你可以试试这个解决方案。

  1. 将您的 VerifyWindow 构造函数更改为:

    公共验证窗口(){初始化组件();}

并删除 TBText 和 _text 代码。

  1. 创建一个名为 VerifyViewModel 的新类

    公共类验证视图模型:INotifyPropertyChanged {公共验证视图模型(字符串内容){ this.TBText = 内容;}

    public string TBText { get; private set; }
    
    #region INPC code - can create an abstract base view model class and put this there instead
    
    public event PropertyChangedEventHandler PropertyChanged;
    
    protected void OnPropertyChanged(string propertyName)
    {
        this.OnPropertyChanged(new PropertyChangedEventArgs(propertyName));
    }
    
    protected virtual void OnPropertyChanged(PropertyChangedEventArgs e)
    {
        var handler = this.PropertyChanged;
        if (handler != null)
        {
            handler(this, e);
        }
    }
    #endregion
    

    }

  2. 如下调用此代码

    var viewmodel = new VerifyViewModel ("移除此技能将清除所有等级花费在此技能上的所有DP。继续吗?");

        var window = new VerifyWindow
        {
            DataContext = viewmodel
        };
        if (window.ShowDialog() == false) return;
