Notes to Inheritors:
When you derive from ContentElement, consider whether you want your element to be focusable, because by default it will not be focusable. If you want your element to be focusable, override the metadata for this property in your derived class static constructor as follows:
where myElement is the class name of the type that you are overriding the metadata value on.
The following example creates a style that makes a Paragraph focusable by default and gives it a visual behavior when it receives focus.
<Style x:Key="FocusableParagraph" TargetType="{x:Type Paragraph}"> <Setter Property="Focusable" Value="true"/> <Style.Triggers> <Trigger Property="IsFocused" Value="True"> <Setter Property = "Background" Value="{StaticResource BlueGreenBrush}"/> </Trigger> </Style.Triggers> </Style>
