Palindrome Number in Windows Store App

In this article I describe Palindrome Numbers in a Windows Store app. We will begin with a brief explanation of Palindrome Numbers.

Palindrome Number

A number that is equal to itself when reversed is called a Palindrome Number.

Example: 121, 131, 11 etc.

Now let us create a Palindrome Number app in Windows Store.

Step 1

First of all you have to create a new Windows Store Application.

• Open Visual Studio 2012
• "File" -> "New" -> "Project..."
• Choose "Template" -> "Visual C#" -> "Window Store app"
• Choose "Blank App (XAML)" then rename the application

Step 2

Write the following XAML code in "Mainpage.Xaml" (that is available in Solution Explorer):

<Page

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

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

    xmlns:local="using:armstrong_app"

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

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

    mc:Ignorable="d">

    <Grid Background="Blue">

        <Grid.RowDefinitions>

            <RowDefinition Height="38*"/>

            <RowDefinition Height="23*"/>

            <RowDefinition Height="31*"/>

            <RowDefinition Height="32*"/>

            <RowDefinition Height="63*"/>

            <RowDefinition Height="581*"/>

        </Grid.RowDefinitions>

        <Grid.ColumnDefinitions>

            <ColumnDefinition Width="161*"/>

            <ColumnDefinition Width="349*"/>

            <ColumnDefinition Width="856*"/>

        </Grid.ColumnDefinitions>

        <TextBlock Text="Check Number is Palindrome numbers or not" FontFamily="Arial" FontSize="14" FontWeight="ExtraBold" Foreground="Red" Grid.Column="1" Grid.Row="1" Grid.ColumnSpan="2"></TextBlock>

        <TextBlock Text="Enter Number:" FontFamily="Arial" FontSize="15" FontWeight="ExtraBold" Foreground="Red" Grid.Column="1" Grid.Row="2"></TextBlock>

        <TextBox x:Name="Textbox1" Width="150" Height="32" VerticalAlignment="Top" Grid.Column="2" Grid.Row="2" HorizontalAlignment="Left" Grid.RowSpan="2" />

        <TextBlock Text="Number is:" FontFamily="Arial" FontSize="15" FontWeight="ExtraBold" Foreground="Red" Grid.Column="1" Grid.Row="3"></TextBlock>

        <TextBlock x:Name="text2" FontFamily="Arial" FontSize="15" FontWeight="ExtraBold" Foreground="Red" Grid.Column="2" Grid.Row="3" Margin="5,0,782,0" Height="32" VerticalAlignment="Bottom" />

        <Button Content="Click" Click="Button1_click" Grid.Column="2" Grid.Row="4" FontSize="15" Foreground="Red" Background="Yellow" Width="137" Height="38" Margin="0,15,0,10" ></Button>

    </Grid>

</Page>

Step 3

Now write the following C# code for the button within "Mainpage.Xaml.cs".

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using Windows.Foundation;

using Windows.Foundation.Collections;

using Windows.UI.Xaml;

using Windows.UI.Xaml.Controls;

using Windows.UI.Xaml.Controls.Primitives;

using Windows.UI.Xaml.Data;

using Windows.UI.Xaml.Input;

using Windows.UI.Xaml.Media;

using Windows.UI.Xaml.Navigation;

 

namespace Palindrome_number_app

{

    public sealed partial class MainPage : Page

    {

        public MainPage()

        {

            this.InitializeComponent();

        }

        protected override void OnNavigatedTo(NavigationEventArgs e)

        {

        }

       private void Button1_click(object sender, RoutedEventArgs e)

        {               

            int num = Convert.ToInt32(Textbox1.Text);

            int rev = 0;

            int num1 = num;

            while (num > 0)

            {

                int r = num % 10;

                num = num / 10;

                rev = rev * 10 + r;

            }

            if (rev == num1)

            {

                text2.Text = "Palindrome numbers";

            }

            else

            {

                text2.Text = "Not Palindrome numbers";

            }

        }

    }

}

 

Step 4

Run the Palindrome app.
