Question

I have a WPF listview populated with a data which is bound through itemsSource. The item bound is a class object called User which contains a handful of properties such as Name, Age, Mail and Info.

What I want to do is be able to double click any listview item and popup an edit dialog which will allow me to change the Mail and Info of that individual. Those changes however will only be committed when i hit OK otherwise they are ignored.

The problem or place where I'm stuck at is, how do i populate the Edit Dialog with the selected listview item's info/mail? How do i commit those changes back to the item and update the main listview? The rest of the code regarding the popup dialog and whatnot is all implemented already.

The Main Dialog:

XAML - Main Dialog

CS - Main Dialog

using System;
using System.Collections.Generic;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Input;

namespace WpfApplication1
{
    /// 
    /// Interaction logic for MainWindow.xaml
    /// 
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            List items = new List();
            items.Add(new User() { Name = "John Doe", Age = 42, Mail = "john@doe-family.com", Info = "A basketball player"});
            items.Add(new User() { Name = "Jane Doe", Age = 39, Mail = "jane@doe-family.com", Info = "A soccer player" });
            items.Add(new User() { Name = "Sammy Doe", Age = 13, Mail = "sammy.doe@gmail.com", Info = "A hockey player" });
            lvDataBinding.ItemsSource = items;
        }

        private void listViewItem_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
            ListViewItem item = sender as ListViewItem;
            object obj = item.Content;
            //User user = sender as User;
            Console.WriteLine(item);

            // popup window
            Window editDialog = new EditWindow();
            editDialog.Owner = this;
            editDialog.ShowDialog();

            if (editDialog.DialogResult.HasValue && editDialog.DialogResult.Value)
            {
                Console.WriteLine("User pressed OK");
                ;
            }
            else
            {
                Console.WriteLine("User pressed Cancel");
            }

        }
    }

    public class User
    {
        public string Name { get; set; }
        public int Age { get; set; }
        public string Mail { get; set; }
        public string Info { get; set; }
    }
}

The Edit Dialog:

XAML - Edit Dialog

CS - Edit Dialog

using System.Windows;

namespace WpfApplication1
{
    /// 
    /// Interaction logic for EditWindow.xaml
    /// 
    public partial class EditWindow : Window
    {
        public EditWindow()
        {
            InitializeComponent();
        }

        private void ButtonOkClick(object sender, RoutedEventArgs e)
        {
            DialogResult = true;
            this.Close();
        }

        private void ButtonCancelClick(object sender, RoutedEventArgs e)
        {
            DialogResult = false;
            this.Close();
        }
    }
}
