copied!<p>If we're going to have fancy code generation, I think I would prefer a way to generate DependancyProperties more easily. The snippit I use is certainly helpful, but I'm not a fan how jumbled the code looks when you have on-changed and coerce callbacks, and metadata options. Maybe I'll try and mock up a sample after work.</p> <p><strong>Edit:</strong> Well, here's one concept. It would look a lot more clever if you pass anonymous methods to attributes, but it's still a step up.</p> <p>Before:</p> <pre><code>[DpDefault("The Void")] [DpCoerce(new CoerceValueCallback(MainWindow.CoerceAddress))] [DpChanged(new PropertyChangedCallback(MainWindow.ChangeAddress1))] [DpChanged(new PropertyChangedCallback(MainWindow.ChangeAddress2))] [DpOptions(FrameworkPropertyMetadataOptions.Inherits)] public string Address { get { return Dp.Get<string>(); } set { if (Dp.Get<string>() != value) { Dp.Set(value); PostOffice.SendMailToTheBoss("I moved!"); } } } </code></pre> <p>After:</p> <pre><code>public string Address { get { return (string)GetValue(AddressProperty); } set { if ((string)GetValue(AddressProperty) != value) { SetValue(AddressProperty, value); PostOffice.SendMailToTheBoss("I moved!"); } } } public static readonly DependencyProperty AddressProperty = DependencyProperty.Register("Address", typeof(string), typeof(MainWindow), new FrameworkPropertyMetadata((string)"The Void", FrameworkPropertyMetadataOptions.Inherits, new PropertyChangedCallback(MainWindow.ChangeAddress1) + new PropertyChangedCallback(MainWindow.ChangeAddress2), new CoerceValueCallback(MainWindow.CoerceAddress))); </code></pre> <p>Typically, only the 'DpDefault' attribute would be used, but even if it doesn't make the code shorter, it certainly makes it clearer. Here would be a more typical example:</p> <p>Before:</p> <pre><code>[DpDefault("The Void")] public string Address { get; set; } </code></pre> <p>After:</p> <pre><code>public string Address { get { return (string)GetValue(AddressProperty); } set { SetValue(AddressProperty, value); } } public static readonly DependencyProperty AddressProperty = DependencyProperty.Register("Address", typeof(string), typeof(MainWindow), new UIPropertyMetadata((string)"The Void")); </code></pre>
