Bing Map Task in Windows Phone 7 Via WCF Service

Introduction

Today, in this article let's dig out another interesting concept in Windows Phone of communicating via a WCF Service to perform some expected operation.

Question: What is Bing Map Task?

In simple terms "It allows to search some specific requested places across map, it enables marking of the interested locations and user can fetch out the details of specific requested place on the map. The zooming option on the map is also available".

Let's start it off now.

Step 1: The complete code of the IService1.cs looks like this.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

namespace Wcf_Bing_Map_Task

{

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.

[ServiceContract]

public interface IService1

{

[OperationContract]

string Search(string a);

}

Step 2: The complete code of the Service1.svc.cs looks like this.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

namespace Wcf_Bing_Map_Task

{

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.

public class Service1 : IService1

{

public string Search(string a)

{

return a;

}

Step 3: The complete code of the Web.Config looks like this.

<?xml version="1.0"?>

<system.web>

</system.web>

<system.serviceModel>

</behavior>

</serviceBehaviors>

</behaviors>

</system.serviceModel>

<system.webServer>

</system.webServer>

</configuration>

Step 4: The complete code of the MainPage.xaml looks like this.

<phone:PhoneApplicationPage

x:Class="Bing_Maps_Direction_Task.MainPage"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"

xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768"

FontFamily="{StaticResource PhoneFontFamilyNormal}"

FontSize="{StaticResource PhoneFontSizeNormal}"

Foreground="{StaticResource PhoneForegroundBrush}"

SupportedOrientations="Portrait" Orientation="Portrait"

shell:SystemTray.IsVisible="True">

<Grid.RowDefinitions>

</Grid.RowDefinitions>

</StackPanel>

</Grid>

<!--<phone:PhoneApplicationPage.ApplicationBar>

<shell:ApplicationBar IsVisible="True" IsMenuEnabled="True">

<shell:ApplicationBarIconButton IconUri="/Images/appbar_button1.png" Text="Button 1"/>

<shell:ApplicationBarIconButton IconUri="/Images/appbar_button2.png" Text="Button 2"/>

<shell:ApplicationBar.MenuItems>

<shell:ApplicationBarMenuItem Text="MenuItem 1"/>

<shell:ApplicationBarMenuItem Text="MenuItem 2"/>

</shell:ApplicationBar.MenuItems>

</shell:ApplicationBar>

</phone:PhoneApplicationPage.ApplicationBar>-->

</phone:PhoneApplicationPage>

Step 5: The complete code of the MainPage.xaml.cs looks like this.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Net;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Animation;

using System.Windows.Shapes;

using Microsoft.Phone.Controls;

using Microsoft.Phone.Tasks;

using Bing_Maps_Direction_Task.ServiceReference1;

namespace Bing_Maps_Direction_Task

{

public partial class MainPage : PhoneApplicationPage

{

// Constructor

public MainPage()

{

InitializeComponent();

}

static void AddCall(object sender, SearchCompletedEventArgs e)

{

BingMapsTask objMapTask = new BingMapsTask();

objMapTask.SearchTerm = e.Result;

objMapTask.ZoomLevel = 2;

objMapTask.Show();

}

private void button1_Click(object sender, RoutedEventArgs e)

{

textBlock2.Text = "";

if (string.IsNullOrEmpty(textBox1.Text))

{

textBlock2.Text = "Please Enter Search Query";

}

else

{

Service1Client objClient = new Service1Client();

objClient.SearchCompleted += new EventHandler<SearchCompletedEventArgs>(AddCall);

objClient.SearchAsync(textBox1.Text);

textBox1.Text = "";

}

Step 6: The output of the application looks like this.

Step 7: The output of the Searched Query Application looks like this.
