Binding objects defined in code-behind

Question

I have some object that is instantiated in code behind, for instance, the XAML is called window.xaml and within the window.xaml.cs

protected Dictionary

        

Answer 1

That's my way to bind to code behind (see property DataTemplateSelector)

public partial class MainWindow : Window
{
  public MainWindow()
  {
    this.DataTemplateSelector = new MyDataTemplateSelector();

    InitializeComponent();

    // ... more initializations ...
  }

  public DataTemplateSelector DataTemplateSelector { get; }

  // ... more code stuff ...
}

In XAML will referenced by RelativeSource via Ancestors up to containing Window, so I'm at my Window class and use the property via Path declaration:

Setting of property DataTemplateSelector before call InitializeComponent depends on missing implementation of IPropertyChanged or use of implementation with DependencyProperty so no communication run on change of property DataTemplateSelector.
