我尝试使用附加属性绑定.但无法让它发挥作用.

public class Attached
{
    public static DependencyProperty TestProperty =
        DependencyProperty.RegisterAttached("TestProperty", typeof(bool), typeof(Attached),
        new FrameworkPropertyMetadata(false, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault | FrameworkPropertyMetadataOptions.Inherits));

    public static bool GetTest(DependencyObject obj)
    {
        return (bool)obj.GetValue(TestProperty);
    }

    public static void SetTest(DependencyObject obj, bool value)
    {
        obj.SetValue(TestProperty, value);
    }
}

XAML代码:

<Window ...>
    <StackPanel local:Attached.Test="true" x:Name="f">
        <CheckBox local:Attached.Test="true" IsChecked="{Binding (local:Attached.Test), Mode=TwoWay, RelativeSource={RelativeSource Self}}" />
        <CheckBox local:Attached.Test="true" IsChecked="{Binding (local:Attached.Test), Mode=TwoWay}" />
    </StackPanel>
</Window>

和绑定错误:

System.Windows.Data Error: 40 : BindingExpression path error: '(local:Attached.Test)' property not found on 'object' ''StackPanel' (Name='f')'. BindingExpression:Path=(local:Attached.Test); DataItem='StackPanel' (Name='f'); …

我如何以编程方式执行以下操作(来自XAML):

<TextBox Name="OrderDateText"
         Text="{Binding Path=OrderDate, StringFormat=dd-MM-yyyy}"

public DateTime OrderDate

现在我有以下内容

TextBox txtboxOrderdDate = new TextBox();

而且我知道我需要做类似的事情

  Binding bindingOrderDate = new Binding();
  bindingOrderDate.Source = "OrderDate";

但我被困在这里......不知道如何继续应用StringFormat,我也不确定SOURCE是正确的方法(我应该使用ElementName吗？)
