WPF C#如何在代码中创建这个绑定？

Question

我想知道如何创建这个绑定，因为 Line.X2 不是依赖属性！ :(

<Line Y1="0" X1="0" Y2="0" Stroke="Blue" StrokeThickness="3" Margin="0 -2 0 -2" X2="{Binding Path=RenderSize.Width, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type StackPanel}}}"/>

Answer 1

Line.X2 is a dependency property 所以你可以用正常的方式来做：

myLine.SetBinding(Line.X2Property,
  new Binding("RenderSize.Width")
  {
    RelativeSource = new RelativeSource(RelativeSourceMode.FindAncestor, typeof(StackPanel), 1)
  });
