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:

</Grid>

using System.Windows.Ink;
using System.Windows.Input;

Step 7: The output of the application looks like this:
![List1.png]()
Step 8: The output of the Nothing Entered Application looks like this:
![List2.png]()
Step 9: The output of the Addition Operation Application looks like this:
![List3.png]()
![List4.png]()
Step 10: The output of the List Picked Item Application looks like this:
![List5.png]()
![List6.png]()
