如何在地图控件中动态添加单选按钮并在单击按钮时显示它们(windows phone 8.1)

Question

在我的地图控件中有多个带有按钮的位置。因此，当我单击该位置的那个特定按钮时，地图控件中应显示两个单选按钮。

                BasicGeoposition bgp = new BasicGeoposition();

                AppBarButton rd = new AppBarButton();
                bgp.Latitude = loct.lat;
                bgp.Longitude = loct.lng;
                Geopoint hwPoint = new Geopoint(bgp);
                MapControl.SetLocation(rd, hwPoint);
                MapControl.SetNormalizedAnchorPoint(rd, new Point(0.5, 0.5));

                map1.Children.Add(rd);

这样我就给地图控件添加了按钮。在那rd_click我应该如何实现在那个位置显示单选按钮

  void rd_Click(object sender, RoutedEventArgs e)
    {
        RadioButton rb = new RadioButton();
        RadioButton rb1 = new RadioButton();
        StackPanel st = new StackPanel();
        st.Children.Add(rb);
        st.Children.Add(rb1);
        // I want to add this stackpanel to the mapcontrol
    }

地图控件中应在按钮附近显示两个单选按钮。请帮助我

首先，您需要设置 StackPanel 的位置，然后将其添加为地图的子项，如下所示：

MapControl.SetLocation(st, new Geopoint(/* Your location info */));
MyMap.Children.Add(st);
