Hi Karl, Page loading with empty listview items from the ObservableCollections.I hv posted my code behind for your reference.

using System;
using System.Collections.Generic;
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.Navigation;
using System.Windows.Shapes;
using System.Collections.ObjectModel;
using System.ComponentModel;

namespace WPFtest
{
/// <summary>
/// Interaction logic for ComboTest.xaml
/// </summary>
public partial class ComboTest : Page
{

        private ObservableCollection<GameData> \_GameCollection =  new ObservableCollection<GameData>();
        private ObservableCollection<Department> \_AvailablePublishers = new ObservableCollection<Department>();
        private ObservableCollection<Role> \_AvailableRoles = new ObservableCollection<Role>();
        private GridViewColumnHeader \_CurSortCol = null;
        private SortAdorner \_CurAdorner = null;

public ComboTest()
{
  \_GameCollection.Add(new GameData { 
    GameName = "World Of Warcraft", 
    Creator = "Blizzard", 
    Publisher = "Blizzard" });
  \_GameCollection.Add(new GameData { 
    GameName = "Halo", 
    Creator = "Bungie", 
    Publisher = "Microsoft" });
  \_GameCollection.Add(new GameData { 
    GameName = "Gears Of War", 
    Creator = "Epic", 
    Publisher = "Microsoft" });


  \_AvailablePublishers.Add(new Department { DeptID = "1", DeptName = "Purchase" });
  \_AvailablePublishers.Add(new Department { DeptID = "2", DeptName = "production" });
  \_AvailablePublishers.Add(new Department { DeptID = "3", DeptName = "Inventory" });    
  //\_AvailablePublishers.Add("Microsoft");
  //\_AvailablePublishers.Add("Blizzard");
  //\_AvailablePublishers.Add("Nintendo");
  //\_AvailablePublishers.Add("Electronic Arts");
  //\_AvailablePublishers.Add("Activision");
  //\_AvailablePublishers.Add("Ubisoft");
  //\_AvailablePublishers.Add("Take-Two Interactive");

  InitializeComponent();
}

public ObservableCollection<GameData> GameCollection
{ get { return \_GameCollection; } }

public ObservableCollection<Department> AvailablePublishers
{ get {

I don't see where you have assigned the DataContext. You must set the ComboTest DataContext to the ComboTest class. In you Loaded event add this line of code: this.DataContext = this;

The ItemsSource is incorrect.

ItemsSource="{Binding ElementName=This

Change to ItemsSource={Binding Path=...} ... is the property name that holds the collection.

This is wrong. Change to: ItemsSource="{Binding Path=AvailablePublishers}"

I looked at your code again, the ComboBox can't see the Page DataContext. There are many ways around this issue. Two simple solutions are; 1. Binding the ItemsSource in code. 2. Add a CollectionViewSource to the Page.Resources section, then bind the ComboBox to the CollectionViewSource. Assign the soure of the CollectionViewSource to your AvailablePublishers. If you use this solution you must set the ComboBox property, IsSynchronizedWithCurrentItem to False since you are binding two ComboBoxes to the same source.
