    copied!<p>I have a very ordinary ViewModel and I am tring to bind a collection of values to a combobox. The problem is nothing is binding. I have checked the ViewModel constructor and the data is being loaded so I suspect its in my XAML but I just cant find out where.</p> <pre><code>public class OwnerOccupierAccountViewModel : ViewModelBase { readonly UserAccountContext _userAccountContext; readonly LoadOperation&lt;Structure&gt; _loadStructures; #region Properties private ObservableCollection&lt;Structure&gt; _structures; public ObservableCollection&lt;Structure&gt; Structures { get { return _structures; } set { _structures = value; RaisePropertyChanged("Structures"); } } private Structure _selectedStructure; public Structure SelectedStructure { get { return _selectedStructure; } set { _selectedStructure = value; RaisePropertyChanged("SelectedStructure"); } } #endregion public OwnerOccupierAccountViewModel() { _userAccountContext = new UserAccountContext(); if (!DesignerProperties.IsInDesignTool) { _loadStructures = _userAccountContext.Load(_userAccountContext.GetStructuresQuery()); _loadStructures.Completed += new EventHandler(_loadStructures_Completed); } } void _loadStructures_Completed(object sender, EventArgs e) { _structures = new ObservableCollection&lt;Structure&gt;(); foreach (var structure in _loadStructures.Entities) { Structures.Add(structure); } } } &lt;UserControl.Resources&gt; &lt;viewmodel:OwnerOccupierAccountViewModel x:Key='ViewModel'&gt;&lt;/viewmodel:OwnerOccupierAccountViewModel&gt; &lt;/UserControl.Resources&gt; &lt;ComboBox x:Name='cboApartments' ItemsSource='{Binding Structures,Source={StaticResource ViewModel},Mode=TwoWay}' Width='200' /&gt; </code></pre>
