Question

我想在我的WP 8.1应用程序中设置MapControl上的Button。问题是Button不在元素的位置，只在Map的左上角，它正在移动。绑定中的位置是Geopoint。这是我的代码：

<Maps:MapControl x:Name="MapEvent" Grid.Row="1">

        <Maps:MapItemsControl ItemsSource="{Binding}">
            <Maps:MapItemsControl.ItemTemplate>
                <DataTemplate>
                    <StackPanel>
                        <Button Maps:MapControl.Location="{Binding Location}" 
                                Maps:MapControl.NormalizedAnchorPoint="0.5,0.5" 
    Content="{Binding Name}"/>
                    </StackPanel>
                </DataTemplate>
            </Maps:MapItemsControl.ItemTemplate>
        </Maps:MapItemsControl>

    </Maps:MapControl>

以下是一些为我工作的代码的摘录：

public class PhotoInfo
{
    public String Label { get; set; }
    public String FileName { get; set; }
    public Geocoordinate Coordinate { get; set; }
    public Point NormalizedAnchorPoint { get { return new Point(0.5, 1); } }
}

我刚才提醒说，不应该Windows.Devices.Geolocation.Geocoordinate而是Windows.Devices.Geolocation.Geopoint。

这就是为m:MapControl.Location绑定Coordinate.Point

的原因

<m:MapControl ZoomLevel="{Binding ZoomLevel}" Center="{Binding Center}"  MapServiceToken="xxx">
    <m:MapItemsControl ItemsSource="{Binding PhotoInfos}">
        <m:MapItemsControl.ItemTemplate>
            <DataTemplate>
                <Image m:MapControl.Location="{Binding Coordinate.Point}" 
                                       Source="ms-appx:///Assets/pushpin.png" 
                               m:MapControl.NormalizedAnchorPoint="{Binding NormalizedAnchorPoint}" Width="20" Height="45" Tapped="Image_Tapped"/> 
            </DataTemplate>
        </m:MapItemsControl.ItemTemplate>
    </m:MapItemsControl>
</m:MapControl>
