<object Fill="colorString"/>
XAML Values
Property Value
Type: System.Windows.Media.BrushA Brush that describes how the shape's interior is painted. The default is null. See Remarks.
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.
Setting the Fill for a line (Line or Polyline) has no effect, because a line has no interior. Use the Stroke and StrokeThickness properties for lines instead.
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 Fill, you must use indirect targeting. For instance, if you are animating the color of a SolidColorBrush that is the Fill of a Rectangle, the syntax would be <ColorAnimation ... Storyboard.TargetProperty="(Rectangle.Fill).(SolidColorBrush.Color)" />.
The area where the Fill applies to a Path is potentially influenced by its geometry data's FillRule.
If a Fill is null (or not specified), there is no hit-testable region within the object.
