Simpler declaration for WPF Dependency Properties


Dependency Properties are a neat feature of WPF, allowing powerful data binding mechanisms.

However, declaring custom properties is not really straightforward and leads to a lot of boilerplate code.
As an example:

using System.Windows;

public class Foo: DependencyObject
    public static readonly DependencyProperty BarProperty = DependencyProperty.Register
        typeof( string ),
        typeof( Foo ),
        new PropertyMetadata()

    public string Bar
        get => this.GetValue( BarProperty ) as string;
        set => this.SetValue( BarProperty, value );

This package provides a way to reduce the amount of code needed to declare such a property, by introducing a custom [DP] attribute.
The new syntax is then:

using System.Windows;
using BetterDP;

public class Foo: DependencyObject
    static Foo()
        DP.InitializeProperties( typeof( Foo ) );

    public string Bar
        get => this.Get< string >();
        set => this.Set( value );


BetterDP will automatically create dependency properties for every property marked with the DP attribute.
However, this unfortunately cannot be done lazily, as dependency properties usually need to be available before constructing an object, especially when using XAML bindings.

This is why the example above uses a static constructor.
Calling DP.InitializeProperties will ensure every dependency property is properly initialized.

Default values

A default value can be provided directly within the [DP] attribute, such as:

[DP( DefaultValue = "hello, world" )]
public string Bar
    get => this.Get< string >();
    set => this.Set( value );

This is the equivalent of setting a default value with PropertyMetadata or FrameworkPropertyMetadata.

Change Handlers

In order to be notified when a property has changed, you may implement the following method in your class:

protected virtual void DidChangeDependencyProperty( string name, object value )

It will automatically be called when a property marked with [DP] has changed.
