Telerik RadExpander in SilverLight 5


Introduction

 

Today, In this article let's play around with another interesting concept of Telerik RadControls.

 

Question:  What is RadExpander?

 

In simple terms "It is a light-weight control which wraps up the user content acting as a placeholder. It enables navigation when required".

 

I think we are now good to go and implement this wonderful 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 WcfRadControls

{// 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 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 WcfRadControls

{// 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 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 ClientAccessPolicy.xml looks like this:
 

<?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 MainPage.xaml looks like this:


<
UserControl x:Class="RadControlsApp.MainPage"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

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

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480">

 <Grid x:Name="LayoutRoot"Width="500"Height="450"Background="LightCyan">

 <TextBlock Grid.Row="1"Height="23"HorizontalAlignment="Left"Margin="72,61,0,0"Name="textBlock1"
   FontFamily="Verdana"FontSize="15"Text="Please Enter First Number: "VerticalAlignment="Top"Width="214" />

<TextBox Grid.Row="1"Height="23"HorizontalAlignment="Left"Margin="320,60,0,0"
   Name
="textBox1"VerticalAlignment="Top"Width="120" />

 <TextBlock Grid.Row="1"Height="23"HorizontalAlignment="Left"Margin="58,121,0,0"FontFamily="Verdana"FontSize="15"
   Name

 <TextBox Grid.Row="1"Height="23"HorizontalAlignment="Left"Margin="320,120,0,0"
    Name
="textBox2"VerticalAlignment="Top"Width="120" />

<telerik:RadExpander HorizontalAlignment="Center"ExpandDirection="Down"Header="Arthmetic Operations"FontFamily="Verdana"FontSize="15" Margin="92,192,74,23" Width="334" Grid.RowSpan="2">

            <StackPanel Orientation="Vertical" Background="LightGoldenrodYellow">

                <TextBlock Name="textBlockAdd"FontFamily="Verdana"FontSize="12"Margin="5" />

                <TextBlock Name="textBlockSub"FontFamily="Verdana"FontSize="12"Margin="6" />

                <TextBlock Name="textBlockMul"FontFamily="Verdana"FontSize="12"Margin="7" />

                <TextBlock Name="textBlockDiv"FontFamily="Verdana"FontSize="12"Margin="8" />

            </StackPanel>

        </telerik:RadExpander>

        <Button Content="Arthmetic Operation"FontFamily="Verdana"FontSize="12"Background="DeepSkyBlue"Height="23" HorizontalAlignment="Left" Margin="320,163,0,0" Name="button1" VerticalAlignment="Top" Width="133" Click="button1_Click"/>

    </Grid>

</UserControl> 


Step 6: 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 RadControlsApp.ServiceReference1;

using Telerik.Windows.Controls;

namespace RadControlsApp

{
    public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();
        }
        private void add_Call(object sender, addCompletedEventArgs e)

        {

            textBlockAdd.Text = "Addition Result is: " + e.Result.ToString();

        }
        private void sub_Call(object sender, subCompletedEventArgs e)

        {

            textBlockSub.Text = "Subtraction Result is: " + e.Result.ToString();

        }
        private void mul_Call(object sender, mulCompletedEventArgs e)

        {

            textBlockMul.Text = "Multiplication Result is: " + e.Result.ToString();

        }
        private void div_Call(object sender, divCompletedEventArgs e)

        {

            textBlockDiv.Text = "Division Result is: " + e.Result.ToString();

        }
        private void button1_Click(object sender, RoutedEventArgs e)

        {

            if (string.IsNullOrEmpty(textBox1.Text) || string.IsNullOrEmpty(textBox2.Text))

            {

                textBlockAdd.Text = "";

                textBlockSub.Text = "";

                textBlockMul.Text = "";

                textBlockDiv.Text = "";

                RadWindow.Alert("Please Enter Some Values");

            }

            else

            {

                objClient.addCompleted += new EventHandler<addCompletedEventArgs>(add_Call);

                objClient.addAsync(Convert.ToDouble(textBox1.Text), Convert.ToDouble(textBox2.Text));

                objClient.subCompleted += new EventHandler<subCompletedEventArgs>(sub_Call);

                objClient.subAsync(Convert.ToDouble(textBox1.Text), Convert.ToDouble(textBox2.Text));

                objClient.mulCompleted += new EventHandler<mulCompletedEventArgs>(mul_Call);

                objClient.mulAsync(Convert.ToDouble(textBox1.Text), Convert.ToDouble(textBox2.Text));

                objClient.divCompleted += new EventHandler<divCompletedEventArgs>(div_Call);

                objClient.divAsync(Convert.ToDouble(textBox1.Text), Convert.ToDouble(textBox2.Text));

                textBox1.Text = "";

                textBox2.Text = "";

            }

        }

         #region Instance Variables

        Service1Client objClient = new Service1Client();

        #endregion

    }

}
 

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

Step 8: The output of the arthmetic operation application looks like this:
