copied!<p>I tried every possible angle for a solution to making a custom brush, from using MarkupExtensions to messing around with TypeConverter attributes, then it dawwned on me: you simply create a wrapper class based on DependencyObject, create a DependencyProperty of type Brush, implement your customization then Bind to the Brush DependencyProperty. </p> <p>Afterwards, put the custom brush in Resources</p> <pre><code> <l:CustomBrush x:Key="CustomBrush" Brush="Magenta" /> </code></pre> <p>Then Bind to it:</p> <pre><code> <Line X1="0" Y1="-5" X2="200" Y2="-5" Stroke="{Binding Source={StaticResource CustomBrush}, Path=Brush}" StrokeThickness="12"/> </code></pre> <p>I think this is better than the MarkupExtension solution because you can't put one in Resources and therefore you have to redefine the custom settings every time you use it.</p> <p>In any case, this would seem to be a simple solution to inheriting from any Wpf object, and with the flexibility of Bindings you can also bind to members of the wrapped Wpf object itself.</p> <p>Here's the simple class:</p> <pre><code>public class CustomBrush : DependencyObject { public CustomBrush() { this.Brush = Brushes.Azure; } #region Brush DependencyProperty [BindableAttribute(true)] public Brush Brush { get { return (Brush)GetValue(BrushProperty); } set { SetValue(BrushProperty, value); } } public static readonly DependencyProperty BrushProperty = DependencyProperty.Register( "Brush", typeof(Brush), typeof(CustomBrush), new UIPropertyMetadata(null)); #endregion } </code></pre>
