WPF C＃如何在代碼中創建THIS綁定？

Question

我想知道，如何創建這個綁定，因爲Line.X2不是依賴項屬性！ :(

<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這樣你就可以以正常的方式做到這一點：

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