Telerik RadListPicker in Windows Phone 7 Via WCF Service


Introduction

The Telerik Rad Controls for Windows Phone 7 can be obtained from http://www.telerik.com/products/windows-phone.aspx.

The Rad Message Box is used to display output in a nice and enhanced UI.

Question:
What is RadListPicker?

In simple terms "It enables user to select a list item from list picker, the items above 5 are displayed in pop mode and below or equals 5 are displayed as per inline mode".

Let's get this implemented practically for a better idea of this!!!

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;
using PhoneApp2;
 
namespace WCF_Rad_List_Picker
{
   
// 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 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;
using PhoneApp2;
 
namespace WCF_Rad_List_Picker
{
   
// 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 the 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>
                                 <!--
To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before
deployment
-->
                                 <
serviceMetadata httpGetEnabled="true"/>
                                 <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid
disclosing exception information
-->
                                 <
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 the MainPage.xaml looks like this:
