将具有依赖性属性的值从一个 class 绑定到 wpf 中的另一个 class 文本框控件

Question

我有两个 classes Radial.xaml.cs 和 ToothDimension.xaml.cs，想要将 class Radial.xaml.cs 文本框控件的值绑定到依赖项属性另一个 class ToothDimension.xaml.cs 效果很好。它不受文本框控件的约束。我需要更改 Radial.xaml.cs 中的 DataContext 吗？我试过这个：

Radial.xaml.cs

public Radial()
    {
     InitializeComponent();
     DataContext = new ToothDimension(); 
    }

Radial.xaml

<TextBlock x:Name="Length" Text="{Binding DataContext.ToothHeight}" HorizontalAlignment="Left" Height="35"/>

ToothDimension.xaml.cs（其中声明了 ToothHeight）

 public Double ToothHeight
    {
        get { return (double)GetValue(ToothHeightProperty); }
        set { SetValue(ToothHeightProperty, value); }
    }

 public static readonly DependencyProperty ToothHeightProperty 
     DependencyProperty.RegisterAttached("ToothHeight", 
     typeof(double), typeof(ToothDimensions), 
     new PropertyMetadata(new PropertyChangedCallback(ToothHeightChanged)));

private static void ToothHeightChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        double value = (double)e.NewValue;
        ToothMeasurements thisControl = d as ToothMeasurements;
    }

Answer 1

请将您的绑定路径更改为ToothHeight。

<TextBlock x:Name="Length" Text="{Binding ToothHeight}" HorizontalAlignment="Left" Height="35"/>

尽管我建议您使用 MVVM 模式。

它绑定正确，我让它工作了。
