问题描述
我想在我的WP 8.1应用程序中设置MapControl上的按钮.问题是Button不在元素的位置,仅在Map的左上方,并且它正在移动.绑定中的位置是Geopoint.这是我的代码:
I want to set the Button on MapControl in my WP 8.1 app. The problem is the Button isn't on location of the element only is on top-left of the Map and it is moving. Location in binding is Geopoint. Here's my code:
<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>
推荐答案
以下是一些对我有用的代码的摘录:
Here is an excerpt of some code working for me :
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); } }
}
我只是提醒人们,不应该在Windows.Devices.Geolocation.Geocoordinate
上绑定,而应该在Windows.Devices.Geolocation.Geopoint
上绑定.
I just reminded that one should not bind on Windows.Devices.Geolocation.Geocoordinate
but on Windows.Devices.Geolocation.Geopoint
.
这就是为什么Coordinate.Point
绑定在Coordinate.Point
<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>
