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):
<Page
    x:Class="Floyd_triangle_app.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Floyd_triangle_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.ColumnDefinitions>
            <ColumnDefinition Width="643*"/>
            <ColumnDefinition Width="723*"/>
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition Height="143*"/>
            <RowDefinition Height="38*"/>
            <RowDefinition Height="43*"/>
            <RowDefinition Height="300*"/>
            <RowDefinition Height="0*"/>
            <RowDefinition Height="39*"/>
            <RowDefinition Height="205*"/>
        </Grid.RowDefinitions>
        <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"   />
 
    </Grid>
</Page>
 
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()
        {
            this.InitializeComponent();
        }
        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.
