wpf - 在代码隐藏 WPF 中绑定(bind)依赖属性

Question

我有 XAML 代码:

<Ellipse x:Name="node" Height="10" Width="10" map:MapCanvas.Latitude="{Binding Latitude}" map:MapCanvas.Longitude="{Binding Longitude}"
                    Fill="Red" Stroke="Red" StrokeThickness="1" Stretch="Uniform" 
                </Ellipse>

还有这个

xmlns:map="clr-namespace:MapControl;assembly=MapControl"

这是 MapCanvas 类中的依赖属性:

    public static readonly DependencyProperty LatitudeProperty =
        DependencyProperty.RegisterAttached("Latitude", typeof(double), typeof(MapCanvas), new PropertyMetadata(double.PositiveInfinity, OnLatitudeLongitudePropertyChanged));


    public static readonly DependencyProperty LongitudeProperty =
        DependencyProperty.RegisterAttached("Longitude", typeof(double), typeof(MapCanvas), new PropertyMetadata(double.PositiveInfinity, OnLatitudeLongitudePropertyChanged));

我知道有类似的问题，但我的问题是我怎样才能在相同的代码中对经度和纬度的 XAML 代码进行合并？

Answer 1

node.SetBinding(MapCanvas.LatitudeProperty, new Binding("Latitude"));

你可以像这样绑定(bind)..
