Menampilkan Map Berdasarkan Longitude dan Latitude Windows Phone

Assalamukum agan semua,,,
untuk mengawali hari pertam di tahun 2015 ini :D, saya ingin memposting tentang Windows Phone lagi, kali ini tentang bagaimana cara Menampilkan Map Berdasarkan Longitude dan Latitude Windows Phone,
biaasanya cara ini digunakan jika kita ingin membuat tempat pariwisata ataupun yang lainnya..

Langkah – langkah Menampilkan Map Berdasarkan Longitude dan Latitude Windows Phone

1. Buat sebuah Project Windows Phone App baru

2. Tambahkan references Windows Phone Toolkit dengan cara klik kanan references > Manage Nuget Packages > Cari Windows Phone Toolkit > Install

2. Tambahkan 1 map, 2 textbox dan textblock dan buat sebuah application bar

<!--LayoutRoot is the root grid where all page content is placed-->    <Grid x:Name="LayoutRoot" Background="Transparent">        <Grid.RowDefinitions>            <RowDefinition Height="Auto"/>            <RowDefinition Height="*"/>        </Grid.RowDefinitions>        <!-- LOCALIZATION NOTE:            To localize the displayed strings copy their values to appropriately named            keys in the app's neutral language resource file (AppResources.resx) then            replace the hard-coded text value between the attributes' quotation marks            with the binding clause whose path points to that string name.            For example:                Text="{Binding Path=LocalizedResources.ApplicationTitle, Source={StaticResource LocalizedStrings}}"            This binding points to the template's string resource named "ApplicationTitle".            Adding supported languages in the Project Properties tab will create a            new resx file per language that can carry the translated values of your            UI strings. The binding in these examples will cause the value of the            attributes to be drawn from the .resx file that matches the            CurrentUICulture of the app at run time.         -->        <!--Uncomment to see an alignment grid to help ensure your controls are            aligned on common boundaries.  The image has a top margin of -32px to            account for the System Tray. Set this to 0 (or remove the margin altogether)            if the System Tray is hidden.            Before shipping remove this XAML and the image itself.-->        <!--<Image Source="/Assets/AlignmentGrid.png" VerticalAlignment="Top" Height="800" Width="480" Margin="0,-32,0,0" Grid.Row="0" Grid.RowSpan="2" IsHitTestVisible="False" />-->        <!--TitlePanel contains the name of the application and page title-->        <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">            <TextBlock Text="Tutorial Koding" Style="{StaticResource PhoneTextNormalStyle}" Margin="12,0"/>            <TextBlock Text="Map" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>        </StackPanel>        <!--ContentPanel - place additional content here-->        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">            <maps:Map x:Name="mymap" HorizontalAlignment="Left" Grid.Row="0" VerticalAlignment="Top" Height="404" Width="456"/>            <TextBlock HorizontalAlignment="Left" Margin="10,429,0,0" TextWrapping="Wrap" Text="Longitude" VerticalAlignment="Top"/>            <TextBox x:Name="txt_longitude" HorizontalAlignment="Left" Height="72" TextWrapping="Wrap" VerticalAlignment="Top" Width="340" Margin="116,404,0,0"/>            <TextBlock HorizontalAlignment="Left" Margin="10,486,0,0" TextWrapping="Wrap" Text="Latitude" VerticalAlignment="Top"/>            <TextBox  x:Name="txt_latitude" HorizontalAlignment="Left" Height="72" TextWrapping="Wrap" VerticalAlignment="Top" Width="340" Margin="116,461,0,0"/>        </Grid>    </Grid>    <phone:PhoneApplicationPage.ApplicationBar>        <shell:ApplicationBar Mode="Default" Opacity="1" IsMenuEnabled="True" IsVisible="True">            <shell:ApplicationBarIconButton x:Name="cari" Text="Cari" IconUri="/Assets/AppBar/feature.search.png" Click="cari_Click"/>            <shell:ApplicationBarIconButton x:Name="zoommore" Text="Zoom In" IconUri="/Assets/AppBar1/add.png" Click="zoommore_Click"/>            <shell:ApplicationBarIconButton x:Name="zoomless" Text="Zoom Out" IconUri="/Assets/AppBar2/minus.png" Click="zoomless_Click"/>        </shell:ApplicationBar>    </phone:PhoneApplicationPage.ApplicationBar>

3. Buka Capabilities pada file WMAppManifest.xml centang ID_CAP_MAP

4. Import 4 namespace dibawah ini pada file .xaml anda

using System.Threading.Tasks;using Windows.Devices.Geolocation;using Microsoft.Phone.Maps.Toolkit;using Microsoft.Phone.Maps.Controls;using System.Windows.Media;

5. Pada event cari_Click tambahkan script dibawah ini

private void cari_Click(object sender, EventArgs e)        {            // Membuat Pushpin            Pushpin mypushpin = new Pushpin();            mypushpin.Content = "Lokasi";            // Menambahkan pushpin ke MapOverlay            MapOverlay myoverlay = new MapOverlay();            myoverlay.Content = mypushpin;            // menyesuaikan koorinate MapOverlay            myoverlay.GeoCoordinate = new System.Device.Location.GeoCoordinate(Convert.ToDouble(txt_latitude.Text), Convert.ToDouble(txt_longitude.Text));            myoverlay.PositionOrigin = new Point(0, 0.5);                        // tambahkan MapOverlay ke MapLayer            MapLayer mylayer = new MapLayer();            mylayer.Add(myoverlay);            // Menambahkan MapLayer ke map            mymap.Layers.Add(mylayer);            // Mengatur posisi tengah map            mymap.Center = new System.Device.Location.GeoCoordinate(Convert.ToDouble(txt_latitude.Text), Convert.ToDouble(txt_longitude.Text));            mymap.ZoomLevel = 14;        }

6. Pada event zoommore_Click dan zoomless_Click tambahkan script dibawah ini

        private void zoommore_Click(object sender, EventArgs e)        {            // memperbesar map            mymap.ZoomLevel = Math.Min(mymap.ZoomLevel + 1, 20);        }        private void zoomless_Click(object sender, EventArgs e)        {            // memperkecil map            mymap.ZoomLevel = Math.Max(mymap.ZoomLevel - 1, 1);        }

7. Jalankan Aplikasi tersebut dengan menekan F5 maka akan seperti gambar dibawah ini
