WPF data binding finishing chapter to an object

Original: WPF data binding finishing chapter to an object

 

Data binding to target 

First, we need an object

  
  
public class Preson
{
private string name;

public string Name
{
get { return name; }
set { name = value; }
}
private string address;

public string Address
{
get { return address; }
set { address = value; }
}
private int age;

public int Age
{
get { return age; }
set { age = value; }
}
}
 
 

Binding data context dependency attribute set

  
  
public MainWindow()
{
InitializeComponent();
Preson = new Preson() { Name = "慧哥", Address = "大连", Age = 30 };
DataContext = Preson;
}



public Preson Preson
{
get { return (Preson)GetValue(PresonProperty); }
set { SetValue(PresonProperty, value); }
}

// Using a DependencyProperty as the backing store for Preson. This enables animation, styling, binding, etc...
public static readonly DependencyProperty PresonProperty =
DependencyProperty.Register( "Preson", typeof(Preson), typeof(MainWindow), new PropertyMetadata( null));
