Now we will look at the code.

[java]
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 Microsoft.Phone.Controls;

namespace ListBoxExample
{
public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();
listBox1.Items.Add("ListBox Demo From Coderzheaven");
}

private void button1_Click(object sender, RoutedEventArgs e)
{
listBox1.Items.Add(textBox1.Text.Trim());
}
}
}
