Working With Themes in Windows Phone 7 Via WCF Service Messaging

Introduction 

Today, in this article let's dig out another area of a Windows Phone section, whereby communicating with a WCF Service to get a pop up message.

Question: What is Theme?

In simple terms "It provides a definite, enhanced look and feel UI for the user accessing Application".

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

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_Theme
{
    // 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 lightthemeMessage();
        [OperationContract]
        string darkthemeMessage();
    }
}

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_Theme
{
    // 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 lightthemeMessage()
        {
            return "You Have Selected: Light Theme ";
        }
           public string darkthemeMessage()
        {
            return "You Have Selected:  Dark Theme ";
        }
    }
}

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>
          <!-- 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 MainPage.xaml looks like this.

<phone:PhoneApplicationPage
    x:Class="Theme.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" Loaded="PhoneApplicationPage_Loaded">
    <!--LayoutRoot is the root grid where all page content is placed-->
    <Grid x:Name="LayoutRoot" Background="Transparent">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
        <!--TitlePanel contains the name of the application and page title-->
        <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
            <TextBlock x:Name="ApplicationTitle" Text="Vijay Theme Application" FontFamily="Verdana" FontSize="22" Style="{StaticResource PhoneTextNormalStyle}"/>
            <TextBlock x:Name="PageTitle" Text="Windows 7 Phone" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
        </StackPanel>
        <!--ContentPanel - place additional content here-->
        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <Ellipse Height="100" HorizontalAlignment="Left" Margin="106,99,0,0" Name="ellipse1" Stroke="Black" StrokeThickness="1" VerticalAlignment="Top" Width="200" Fill="Orange" OpacityMask="#FF31BE31" />
        </Grid>
    </Grid>
    <!--Sample code showing usage of ApplicationBar-->
    <!--<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 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 Theme.ServiceReference1;
namespace Theme
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
        }
        private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
        {
            settheme();
        }
        protected void settheme()
        {
            Visibility v = (Visibility)Resources["PhoneLightThemeVisibility"];
            Service1Client obj_Client = new Service1Client();
            if (v == System.Windows.Visibility.Visible)
            {
                obj_Client.lightthemeMessageCompleted += new EventHandler<lightthemeMessageCompletedEventArgs>(light_Call);
                obj_Client.lightthemeMessageAsync();
            }
            else
            {
                obj_Client.darkthemeMessageCompleted += new EventHandler<darkthemeMessageCompletedEventArgs>(dark_Call);
                obj_Client.darkthemeMessageAsync();
            }
        }
        static void light_Call(object sender, lightthemeMessageCompletedEventArgs e)
        {
            MessageBox.Show(e.Result.ToString());
        }
       static void dark_Call(object sender, darkthemeMessageCompletedEventArgs e)
        {
            MessageBox.Show(e.Result.ToString());
        }
    }
}

Step 6 : The output of the Dark Theme Application looks like this.
