WPF Bind ListBox to SelectionChanged ComboBox in XAML
I want to bind the selection change of the combo box to update my list
box, but my xaml code is probably wrong.
This is my Collection that takes the data from the Service.
public class WorkersCollection
{
private WorkerClient client = new WorkerClient();
public ObservableCollection<Worker> Workers { get; set; }
public WorkersCollection()
{
Workers = new ObservableCollection<Worker>();
}
public ICollection<Worker> GetAllWorkers()
{
foreach (var worker in client.GetAllWorkers())
{
Workers.Add(worker);
}
return Workers;
}
}
My DataContext is workers:
public partial class MainWindow : Window
{
WorkersCollection workers;
public MainWindow()
{
InitializeComponent();
workers = new WorkersCollection();
this.DataContext = workers;
workers.GetAllWorkers();
}
}
and in XAML:
<ComboBox Name="cbxWorkers" HorizontalContentAlignment="Right"
SelectedItem="{Binding Workers}" ItemsSource="{Binding Workers}">
<ComboBox.ItemTemplate>
<DataTemplate>
<ComboBoxItem Content="{Binding LastName}" />
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
<ListBox Grid.Row="3" ItemTemplate="{StaticResource WorkersTemplate}"
ItemsSource="{Binding ElementName=cbxWorkers, Path=SelectedItem}" />
How can I fix it?
