WPF C#如何在代码中创建THIS绑定?
问题描述：
我想知道，如何创建此绑定，因为Line.X2不是依赖项属性！ :(
I wonder, how to create this binding, since Line.X2 IS NOT dependency property! :(
<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}}}"/>
答
Line.X2 是一个依赖项属性，因此您可以按照常规方式执行此操作:
Line.X2 is a dependency property so you can do this in the normal way:
myLine.SetBinding(Line.X2Property,
new Binding("RenderSize.Width")
{
RelativeSource = new RelativeSource(RelativeSourceMode.FindAncestor, typeof(StackPanel), 1)
});
