Introduction
First before we begin start working with the Color Slider, we need to download the Coding4Fun Toolkit from http://coding4fun.codeplex.com/. Later add Coding4Fun.Phone.Controls.dll as a reference for our newly created project.
Today, in this article let's learn another new concept related to Window Phone 7, whereby communicating with WCF Service to perform some operation.
Question: What is a Color Slider?
In simple terms "It provides a slider which is a way to access the required color from color space".
Let's get this started off now!!!
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 SilverlightApplication1;
namespace WCF_Color_Slider_Application
{
// 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 colorName(string 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;
using SilverlightApplication1;
namespace WCF_Color_Slider_Application
{
// 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 colorName(string 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 MainPage.xaml looks like this:
<phone:PhoneApplicationPage x:Class="Color_Slider_Application.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:phone="clr

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="Color Slider 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="69" HorizontalAlignment="Left" Margin="295,107,0,0" Name="ellipse1" Stroke="Black"StrokeThickness="1" VerticalAlignment="Top" Width="139" />
<TextBox Height="72" HorizontalAlignment="Left" Margin="277,6,0,0" Name="textBox1"
VerticalAlignment="Top" Width="173" />
<TextBlock Height="30" HorizontalAlignment="Left" Margin="16,28,0,0" Name="textBlock1" Text="Your
Selected Color # " FontFamily="Verdana" FontSize="22" VerticalAlignment="Top" />
<TextBlock Height="30" HorizontalAlignment="Left" Margin="16,133,0,0" Name="textBlock2" Text="Your
Selected Color is: " FontFamily="Verdana" FontSize="22" VerticalAlignment="Top" />
</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 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 Microsoft.Phone.Controls;
using Coding4Fun.Phone.Controls;
using Color_Slider_Application.ServiceReference1;
using SilverlightApplication1;
namespace Color_Slider_Application
{
public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();
}
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
objSlider.Height = 100;
objSlider.Width = 450;
objSlider.Orientation = System.Windows.Controls.Orientation.Horizontal;
objSlider.HorizontalAlignment = System.Windows.HorizontalAlignment.Stretch;
objSlider.VerticalAlignment = System.Windows.VerticalAlignment.Center;
objSlider.ColorChanged +=new ColorBaseControl.ColorChangedHandler(color_Call);
this.ContentPanel.Children.Add(objSlider);
}
private void colorName_Call(object sender, colorNameCompletedEventArgs e)
{
textBox1.Text = e.Result;
}
private void color_Call(object sender, Color newcolor)
{
objClient.colorNameCompleted += new EventHandler<colorNameCompletedEventArgs>(colorName_Call);
objClient.colorNameAsync(newcolor.ToString());
ellipse1.Fill = new SolidColorBrush(newcolor);
}
#region Instance Variables ColorSlider objSlider = new ColorSlider();
Service1Client objClient = new Service1Client();
#endregion
}
}
Step 6: The output of the application looks like this:
Step 7: The output of the Color Chosen Application looks like this:
I hope this article is useful for you. I look forward for your comments and feedback. Thanks Vijay Prativadi.
