Introduction

In this article let's concentrate on another Silverlight application, whereby communicating with a WCF Service to perform some operation.

The Telerik Rad Controls for Silverlight can be found from http://www.telerik.com/products/silverlight/controls.aspx.

The Rad Window is used to display the output in a nice and enhanced UI.

Question: What is RadBarCode?

In simple terms "It provides light weighted and easy systematic approach to generate bar-codes, it used to ensure unique id given to each product when evaluating".

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;
namespace Wcf_Rad_Bar
{
   
// 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]
        int bar(int 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_Rad_Bar
{
   
// 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 int bar(int a)
        {
            return a;
        }
    }
}

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 Clientaccesspolicy.xml looks like this (to avoid cross domain problem in Silverlight).

<?xml version="1.0" encoding="utf-8"?>
<
access-policy>
    <cross-domain-access>
        <policy>
            <allow-from http-request-headers="SOAPAction">
                <domain uri="*"/>
            </allow-from>
            <grant-to>
                <resource path="/" include-subpaths="true"/>
            </grant-to>
        </policy>
    </cross-domain-access>
</
access-policy>

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

<UserControl x:Class="Rad_Bar_App.MainPage"
              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
              xmlns:x

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

              xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
              mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480">
    <Grid x:Name="LayoutRoot" Width="628" Height="452">
        <telerik:RadBarcode128 Name="radBar1"
                               ShowChecksum="False"
                               Margin="104,0,113,189"
                               Height="89"
                               VerticalAlignment
="Bottom">
       </telerik:RadBarcode128>
        <TextBlock Height="23"
                   HorizontalAlignment="Left"
                   Margin="191,12,0,0"
                   Name="textBlock1" Text="Please Enter Bar Code Number"
                   FontFamily="Verdana"
                   FontSize="15"
                   VerticalAlignment
="Top" />
 
        <TextBox Height="23"
                HorizontalAlignment="Left"
                 Margin="248,41,0,0"
                 Name="textBox1"
                 VerticalAlignment="Top"
                 Width
="120" />
        <Button Content="Send BarCode"
                FontFamily="Verdana"
                Background="DeepSkyBlue"
                FontSize="15"
                Height="23"
                HorizontalAlignment="Left"
                Margin="235,82,0,0"
                Name="button1"
                VerticalAlignment="Top"
                Width="133"
                Click
="button1_Click"/>
 
        <telerik:RadBarcode93 Name="radBar93"
                             Margin="104,336,113,22" ShowChecksum
="False">
 
        </telerik:RadBarcode93>
       <TextBlock Height="23"
                   HorizontalAlignment="Left"
                   Margin="235,289,0,0"
                   Name="textBlock2"
                   Text
="RadBarCode93"
                   FontFamily="Verdana"
                   FontSize="15"
                   VerticalAlignment="Top"
                   Width="170"
                   FontWeight
="Bold"
                   Visibility="Collapsed"
                   /> 
        <TextBlock Height="23"
                   HorizontalAlignment="Left"
                   Margin="234,129,0,0"
                   Name="textBlock3"
                   Text
="RadBarCode128"
                   FontFamily="Verdana"
                   FontSize="15"
                   FontWeight="Bold"
                   VerticalAlignment="Top"
                   Width="134"
                   Visibility
="Collapsed"/>
    </Grid>
</
UserControl>

Step 6 : 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 Telerik.Windows.Controls;
using Rad_Bar_App.ServiceReference1;
namespace Rad_Bar_App
{    public partial class MainPage :
UserControl
  {
        public MainPage()
        {
            InitializeComponent();
        }
       private void bar_Call(object sender, barCompletedEventArgs e)
        {
            radBar1.Visibility = System.Windows.Visibility.Visible;
            radBar93.Visibility = System.Windows.Visibility.Visible;
            radBar1.Text = e.Result.ToString();
            radBar93.Text = e.Result.ToString();
            textBlock2.Visibility = System.Windows.Visibility.Visible;
            textBlock3.Visibility = System.Windows.Visibility.Visible;
        }
        private void button1_Click(object sender, RoutedEventArgs e)
        {
            textBlock2.Visibility = System.Windows.Visibility.Collapsed;
            textBlock3.Visibility = System.Windows.Visibility.Collapsed;
            radBar1.Visibility = System.Windows.Visibility.Collapsed;
            radBar93.Visibility = System.Windows.Visibility.Collapsed;
            if (string.IsNullOrEmpty(textBox1.Text))
            {
                RadWindow.Alert("Please Enter Some Values");
           }
           
else
            {
                Service1Client obj_Client = new Service1Client();
                obj_Client.barCompleted += new EventHandler<barCompletedEventArgs>(bar_Call);
                obj_Client.barAsync(Convert.ToInt32(textBox1.Text));
                textBox1.Text = "";
            }
        }
    }
}

Step 7 : The output of the application looks like this.
