Muliple Pushpins in Windows Phone 8.1

问题

I am using MapControl to display map. I have MapServiceToken too. I have added custom pushpin using MapIcon and assigned this object to Map. It is working fine. But when i try to add multiple pushpins using same scenario and assign it to map so i am getting last pushpin on the map. Rest of other pushpins are not getting visible. Kindly tell me any simple solution to this problem. Thanks

You can binding your pushpins on map without MapIcon.

Add in xaml

<Maps:MapControl x:Name="MapLocationsControl" MapServiceToken="add your token here">
        <Maps:MapItemsControl x:Name="mapitem">
            <Maps:MapItemsControl.ItemTemplate>
                <DataTemplate>

                        <Image Height="50" Width="50"
                               Source="{Binding image,Mode=OneWay}"
                       Maps:MapControl.Location="{Binding Geopoint}"/>

                </DataTemplate>
            </Maps:MapItemsControl.ItemTemplate>
        </Maps:MapItemsControl>
    </Maps:MapControl>

And in c# binding items in MapControl source

 mapitem.ItemsSource = items;

Where items is observable collection with MapItems class items. You can add items with Add().

ObservableCollection<MapItem> items = new ObservableCollection<MapItem>();

items.Add(new MapItem(lat,lng, "Assets/pushpinicon.png"));

MapItem Class is like this

public class MapItem {

public Geopoint Geopoint { get; set; }

public string image {get; set;}

    public MapItem(double lat , double lng , string img)
    {

        Geopoint = new Geopoint(new BasicGeoposition() { Latitude = lat, Longitude = lng });

        image=img;
     }
}
