Wrap Panel in Windows Phone 7 via WCF Service

Introduction

In this article let' see one of the good and interesting concept in windows phone whereby communicating with WCF Service to perform some expected operation. This concept made the phone user to handle the task easily in light weighted mode.

Question Arises: What is Wrap Panel?

The Wrap Panel acts as a container which holds set of controls to provide consistent look for the user.

So, let's get it started off.

Step 1 : The Complete Code of 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_Wrap_Panel
{
// 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]
double Add(double a, double b);
[OperationContract]
double Sub(double a, double b);
[OperationContract]
double Mul(double a, double b);
[OperationContract]
double Div(double a, double b);
}
}

Step 2 : The Complete Code of 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_Wrap_Panel
{
// 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 double Add(double a, double b)
{
return a + b;
}
public double Sub(double a, double b)
{
return a - b;
}
public double Mul(double a, double b)
{
return a * b;
}
public double Div(double a, double b)
{
return a / b;
}
}
}

Step 3 : The Complete Code of Web.Config looks like this:

<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>

<serviceMetadata httpGetEnabled="true"/>

<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>

Step 4 : The Complete Code of MainPage.xaml looks like this:

<phone:PhoneApplicationPage xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"
x:Class="Wrap_Panel_Application.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

</Grid>
</Grid>
</phone:PhoneApplicationPage>

Step 5 : The Complete Code of 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 Wrap_Panel_Application.ServiceReference1;
namespace Wrap_Panel_Application
{
public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();
}
static void AddCall(object sender, AddCompletedEventArgs e)
{
MessageBox.Show(" The Addition Result is: " + e.Result.ToString());
}
private void btnAdd_Click(object sender, RoutedEventArgs e)
{
textBlock1.Text = "";
if (string.IsNullOrEmpty(textBox1.Text) || string.IsNullOrEmpty(textBox2.Text))
{
textBlock1.Text = "Please Enter Values";
textBlock1.Foreground = new SolidColorBrush(Colors.Red);
}
else
{
Service1Client objClient = new Service1Client();
objClient.AddCompleted += new EventHandler<AddCompletedEventArgs>(AddCall);
objClient.AddAsync(Convert.ToDouble(textBox1.Text), Convert.ToDouble(textBox2.Text));
textBox1.Text = ""; textBox2.Text = "";
}
}
static void SubCall(object sender, SubCompletedEventArgs e)
{

}
private void btnSub_Click(object sender, RoutedEventArgs e)
{

objClient.SubAsync(Convert.ToDouble(textBox1.Text), Convert.ToDouble(textBox2.Text));
textBox1.Text = ""; textBox2.Text = "";
}
}
static void MulCall(object sender, MulCompletedEventArgs e)
{
MessageBox.Show(" The Multiplication Result is: " + e.Result.ToString());
}
private void btnMul_Click(object sender, RoutedEventArgs e)
{

objClient.MulCompleted += new EventHandler<MulCompletedEventArgs>(MulCall);
objClient.MulAsync(Convert.ToDouble(textBox1.Text), Convert.ToDouble(textBox2.Text));
textBox1.Text = ""; textBox2.Text = "";
}
}
static void DivCall(object sender, DivCompletedEventArgs e)

objClient.DivAsync(Convert.ToDouble(textBox1.Text), Convert.ToDouble(textBox2.Text));
textBox1.Text = "";
textBox2.Text = "";
}
}
}
}

Step 6 : The Output of the Application looks like this:

Wrap Panel in windows phone 7

Step 7 : The Addition Operation Output Application looks like this:

Step 8 : The Nothing Entered Output Application looks like this:
