Xamarin.Forms Brushes

A brush enables you to paint an area, such as the background of a control, using different approaches. Brush support in Xamarin.Forms is available in the Xamarin.Forms namespace on iOS, Android, macOS, the Universal Windows Platform (UWP), and the Windows Presentation Foundation (WPF).

The Brush class is an abstract class that paints an area with its output. Classes that derive from Brush describe different ways of painting an area. The following list describes the different brush types available in Xamarin.Forms:

• SolidColorBrush, which paints an area with a solid color. For more information, see Xamarin.Forms Brushes: Solid colors.
• LinearGradientBrush, which paints an area with a linear gradient. For more information, see Xamarin.Forms Brushes: Linear gradients.
• RadialGradientBrush, which paints an area with a radial gradient. For more information, see Xamarin.Forms Brushes: Radial gradients.

Instances of these brush types can be assigned to the Stroke and Fill properties of a Shape, and the Background property of a VisualElement.

Note

The VisualElement.Background property enables brushes to be used as the background in any control.

The Brush class also has an IsNullOrEmpty method that returns a bool that represents whether the brush is defined or not.
