Formatting In Percentages Using Windows Store Apps

Introduction

Today I am going to explain the PercentFormatter class which resides in the Windows.Globalization.NumberFormatting namespace. This class is used to calculate the result and returns the percentage of that result or number. Or we can say that this class is used to format and parse the percentages. This class is only applicable to the Windows Store apps. Now to work with this class use the following steps.

Step 1

Open Visual Studio 2012 and click on "File" -> "New" -> "Project...", select Windows Store inside Visual C# from the left side pane and BlankPage from the center pane.

Step 2

Add the namespace:

using Windows.Globalization.NumberFormatting;

Step 3

Create the instance of this class as:

PercentFormatter pf = new PercentFormatter();

Step 4

Open the MainPage.xaml file and write the code as:

<Page

x:Class="App35.MainPage"

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

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

xmlns:local="using:App35"

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

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

mc:Ignorable="d">

<Grid.RowDefinitions>

</Grid.RowDefinitions>

<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>

</Grid>

</Page>

Step 5

Write the following code in MainPage.xaml.cs:

namespace App35

{

public sealed partial class MainPage : Page

{

public MainPage()

{

this.InitializeComponent();

}

private void Button_Click_1(object sender, RoutedEventArgs e)

{

PercentFormatter pf = new PercentFormatter();

double randomNumber = new Random().NextDouble();

ulong fixedNumber = 50;

Random_Number.Text = " " + randomNumber;

Percent_Formatter.Text = " " + pf.Format(randomNumber);

Fixed_Number.Text = "" + fixedNumber;

pf.IsGrouped = true;

Percent_Formatter_Grouped.Text = " " + pf.Format(fixedNumber);

pf.FractionDigits = 0;

Percent_Formatter_NoFractonal.Text = "" + pf.Format(fixedNumber);

pf.IsDecimalPointAlwaysDisplayed = true;

Percent_Formatter_alwaysdecimal.Text = "" + pf.Format(fixedNumber);

}

}

Step 6

Now Run the application. The output of this application looks like:
