3. Сделали то, что просили…

4. XAML и связывание данных ImplicitDataTemplates RelativeSource Ancestor Bindings Binding In Style Setters Markup Extensions Databinding Debugging DataContextChanged Event (Post Beta) UpdateSourceTrigger (Post Beta)

5. Implicit Data Templates

6. Шаблоны основаны на типе Учитывается иерархия наследования

7. Relative Source

8. <TextBlock Text="{Binding StateName}" Visibility="{Binding IsDropDownOpen, RelativeSource={RelativeSource FindAncestor AncestorType=ComboBox}, Converter={StaticResource BoolToVisibilityConverter} }"/>

9. Markup Extensions

10. public class MethodInvokeExtension : IMarkupExtension { // Properties Exposed in XAML as Intellisense Love public String Method { get; set; } // Invoked by the XAML Parser @ runtime public object ProvideValue(IServiceProvider serviceProvider) { <UserControl x:Class="AppointmentsView" xmlns:MyUtils="clr-namespace:TestApp;assembly=TestApp">... <ComboBox Name="appointmentsListBox" SelectionChanged="{MyUtils:MethodInvoke Method=OnAppointmentChanged}"

11. Binding Style Setters

12. Создайте класс для представления значений Создайте экземпляр класса в ресурсах Используйте связывание данных в стилях <Setter Property="Foreground" Value="{Binding ForegroundColor, Source={StaticResource MyAppStyles}}"

13. DataContextChanged this.DataContextChanged += View_DataContextChanged; … void View_DataContextChanged(object sender, DependencyPropertyChangedEventArgs e) { INotifyPropertyChanged customer; customer = e.OldValue as INotifyPropertyChanged; if (customer != null) customer.PropertyChanged -= customer_PropertyChanged; customer = e.NewValue as INotifyPropertyChanged; if (customer != null) customer.PropertyChanged += customer_PropertyChanged; }

14. UpdateSourceTrigger <TextBox Name="vinTextBox" Text="{Binding SelectedClaim.InsuredVIN, Mode=TwoWay}" UpdateSourceTrigger=PropertyChanged}"
