title: WPF ComboBox Formatting
body: <p>This works perfectly, except that I need some kind of template to display the Selected Item of the ComboBox? Currently the bindings work as expected, but the ComboBox displays: "Systems.Windows.Controls.ListView Items.Count:20".</p>
  
  <p>I would like it to display a horizontal StackPanel or Grid containing the GridViewColumn items (ID, Closed Date, Customer, Job Name).</p>
  
  <pre><code>&lt;ComboBox Grid.Row="0" VerticalAlignment="Top" HorizontalAlignment="Left" 
                        IsTextSearchEnabled="False" Width="700"                                   
                        IsEditable="True"&gt;
  
                  &lt;ListView ItemsSource="{Binding ActiveJobObservCollection}" 
                            SelectedItem="{Binding SelectedActiveJob, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                            ScrollViewer.VerticalScrollBarVisibility="Auto"&gt;
                      &lt;ListView.View&gt;
                          &lt;GridView&gt;
                              &lt;GridViewColumn Width="100" Header="Job ID" DisplayMemberBinding="{Binding JobID}"/&gt;
                              &lt;GridViewColumn Width="100" Header="Closed Date" DisplayMemberBinding="{Binding ClosedDate, StringFormat=d}"/&gt;
                              &lt;GridViewColumn Width="200" Header="Customer Name" DisplayMemberBinding="{Binding CustomerName}"/&gt;
                              &lt;GridViewColumn Width="300" Header="Job Name" DisplayMemberBinding="{Binding JobName}"/&gt;
                          &lt;/GridView&gt;
                      &lt;/ListView.View&gt;
                  &lt;/ListView&gt;
  &lt;/ComboBox&gt;
