Floyd's Triangle in Windows Store App

In this article I explain Floyd's Triangle in programming languages. But let us first of all understand what Floyd's Triangle is. 

Floyd's Triangle

It is a right angle triangle of a natural number.

Use the following step to create the Floyd's Triangle in a Windows Store app.

Step 1

First of all you have to create a New Window 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):










    <Grid Background="Blue">


            <ColumnDefinition Width="643*"/>

            <ColumnDefinition Width="723*"/>



            <RowDefinition Height="143*"/>

            <RowDefinition Height="38*"/>

            <RowDefinition Height="43*"/>

            <RowDefinition Height="300*"/>

            <RowDefinition Height="0*"/>

            <RowDefinition Height="39*"/>

            <RowDefinition Height="205*"/>


        <TextBlock Text="Floyd Trangle Example" FontSize="25" FontWeight="ExtraBold" Grid.ColumnSpan="2" Grid.Row="1" TextAlignment="Center" Foreground="Red" ></TextBlock>

        <TextBlock Text="Enter Line no:" FontSize="25" FontWeight="ExtraBold" Grid.Column="0" Grid.Row="2" Foreground="Red" TextAlignment="Right"  ></TextBlock>

        <TextBox x:Name="textbox1" Grid.Column="1" Grid.Row="2" Width="150" Height="35" VerticalAlignment="Top" HorizontalAlignment="Left" />

        <TextBlock x:Name="text1" FontSize="25" FontWeight="ExtraBold" Grid.Column="1" Grid.Row="3" Foreground="Red" TextWrapping="Wrap" Width="466" HorizontalAlignment="Left" />

        <Button x:Name="Button1" Content="Click" Click="Button1_Click" Foreground="Red" Background="Yellow" Grid.Column="1" Grid.Row="2"  Height="44" Width="141" VerticalAlignment="Top" Grid.RowSpan="2"  HorizontalAlignment="Center"   Margin="177,0,405,0"   />





Step 3

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

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;

using Windows.UI;


namespace Floyd_triangle_app


    public sealed partial class MainPage : Page


        public MainPage()




        protected override void OnNavigatedTo(NavigationEventArgs e)



        private void Button1_Click(object sender, RoutedEventArgs e)


            text1.Text = "";

            int range = Convert.ToInt32(textbox1.Text);

            int k = 1;

            for (int i = 1; i <= range ; i++)


                for (int j = 1; j <= i; j++,k++)


                    text1.Text += k.ToString();

                    text1.Text += "  ";


                text1.Text += Environment.NewLine;






Step 4

Run your App.
