Bing Map Direction 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 Direction Task?

In simple terms "It enables to find out route directions between requested source and destination, the requested places are displayed accordingly with distance (Miles/Kilometers) from source and clear way of directions to reach destination".

I think we all are now good to go and implement this interesting concept.

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_Maps_Direction

{

// 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 To(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_Maps_Direction

{

// 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 To(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_Directions_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 System.Device.Location;

using Bing_Maps_Directions_Task.ServiceReference1;

namespace Bing_Maps_Directions_Task

{

public partial class MainPage : PhoneApplicationPage

{

// Constructor

public MainPage()

{

InitializeComponent();

}

void toCall(object sender, ToCompletedEventArgs e)

{

LabeledMapLocation from = new LabeledMapLocation("Hyderabad, Andhra Pradesh", null);

LabeledMapLocation to = new LabeledMapLocation(e.Result, null);

objDirectionTask.Start = from;

objDirectionTask.End = to;

objDirectionTask.Show();

}

private void button1_Click(object sender, RoutedEventArgs e)

{

textBlock3.Text = "";

if (string.IsNullOrEmpty(textBox2.Text))

{

textBlock3.Text = "Please Enter Values";

}

else

{

Service1Client objClient = new Service1Client();

objClient.ToCompleted += new EventHandler<ToCompletedEventArgs>(toCall);

objClient.ToAsync(textBox2.Text);

textBox2.Text = "";

}

#region object variables

BingMapsDirectionsTask objDirectionTask = new BingMapsDirectionsTask();

#endregion

}

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

Step 7: The Output To (Destination) Output Application looks like this.

I hope this article is useful for you. I look forward for your comments and feedback.
