Gets or sets the Brush that specifies how to paint the interior of the shape.
Assembly: System.Windows (in System.Windows.dll)
Dependency property identifier field: FillProperty
For rendering, the null default value is interpreted as a Brush that has no color value, but renders as Transparent. A value of a null Brush has no hit-testable region, while a value of an actual brush with a color value of Transparent is hit-testable.
Some brush types (SolidColorBrush) support a XAML attribute syntax, whereas other brush types (ImageBrush, LinearGradientBrush, RadialGradientBrush) only support an object element syntax. This is why two versions of XAML syntax are shown for this property.
When animating a , you must use indirect targeting. For instance, if you are animating the color of a SolidColorBrush that is the of a Rectangle, the syntax would be <ColorAnimation ... Storyboard.TargetProperty="(Rectangle.Fill).(SolidColorBrush.Color)" />.
If a is null (or not specified), there is no hit-testable region within the object.
