WPF Listbox Binding from MS SQL Database 02

WPF Listbox SelectionChanged – Get SelectedItem

Let’s see how we can get WPF Listbox SelectedItem and use it for displaying in a WPF Messagebox. To see How to Bind WPF Listbox from Database please visit this Post. WPF Listbox SelectionChanged – Get SelectedItem

WPF Listbox SelectionChanged - Get SelectedItem 02

Make a simple Listbox in your WPF form as below :


<Window x:Class="WpfApplication2.MainWindow"
Title="WPF ListBox from MS SQL Database" Height="350" Width="525" WindowState="Maximized" WindowStyle="ThreeDBorderWindow">
<StackPanel Orientation="Vertical">
<TextBlock Text="WPF ListBox from MS SQL Database" FontSize="25" FontWeight="Bold" Margin="5" HorizontalAlignment="Left"/>
<ListBox Name="lstBox" HorizontalAlignment="Left" VerticalAlignment="Center"
Background="#fff" SelectionChanged="lstBox_SelectionChanged_1" >
<StackPanel Orientation="Horizontal" HorizontalAlignment="Left" >
<TextBlock Text="{Binding id}" Margin="2" FontWeight="Bold"/>
<TextBlock Text="{Binding country}" Margin="2" />
<TextBlock Text="{Binding ondate}" Margin="2"/>

SelectionChanged method will be called when the user changes and selects an item from our WPF Listbox. And for getting the selected item here is the code :

private void lstBox_SelectionChanged_1(object sender, SelectionChangedEventArgs e)
var item = (ListBox)sender;
var country = (Countries)item.SelectedItem;
MessageBox.Show("You Selected " + + "(ID: " + + ", added on Date : " + country.ondate + ")");

I’m having a Countries class which I’m using to Bind my WPF Listbox from Database.

Here is the complete code :

MainWindow.xaml.cs :

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace WpfApplication2
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
static String connectionString = @"Data Source=vibes\sqlexpress;Initial Catalog=ParallelCodes;User ID=sa;Password=789;";
SqlConnection con;
SqlCommand cmd;
SqlDataAdapter adapter;
DataSet ds;
SqlDataReader reader;

public MainWindow()

public void FillList()
con = new SqlConnection(connectionString);
cmd = new SqlCommand("select * from tblCountries", con);
adapter = new SqlDataAdapter(cmd);
ds = new DataSet();
adapter.Fill(ds, "tblCountries");
Countries co = new Countries();
IList<Countries> co1 = new List<Countries>();

foreach (DataRow dr in ds.Tables[0].Rows)
co1.Add(new Countries
id = Convert.ToInt32(dr[0].ToString()),
country = dr[1].ToString(),
ondate = Convert.ToDateTime(dr[2].ToString())
lstBox.ItemsSource = co1;
catch (Exception ex)

ds = null;

private void lstBox_SelectionChanged_1(object sender, SelectionChangedEventArgs e)
var item = (ListBox)sender;
var country = (Countries)item.SelectedItem;
MessageBox.Show("You Selected " + + "(ID: " + + ", added on Date : " + country.ondate + ")");

public class Countries
public int id { get; set; }
public string country { get; set; }
public DateTime ondate { get; set; }
