Control.Background Property

Gets or sets a brush that describes the background of a control. This is a  dependency property.

Namespace:  System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)
[BindableAttribute(true)]
public Brush Background { get; set; }
For XAML information, see the Brush type.

Property Value

Type: System.Windows.Media.Brush
The brush that is used to fill the background of the control. The default is Brushes.Transparent.

The Background property applies only to the resting state of a control. The default style of the control specifies its appearance when the state of the control changes. For example, if you set the Background property on a Button, the button has that value only when it is not pressed or disabled. If you want to create a control that has a more advanced customization of the background, you must define the control's style.

This property only affects a control whose template uses the Background property as a parameter. On other controls, this property has no impact.

The following example shows how to set the background property of a control.

<Button Name="btn" Background="Red" 
        Click="ChangeBackground">
  Background
</Button>
void ChangeBackground(object sender, RoutedEventArgs e)
{
    if (btn.Background == Brushes.Red)
    {
        btn.Background = new LinearGradientBrush(Colors.LightBlue, Colors.SlateBlue, 90);
        btn.Content = "Control background changes from red to a blue gradient.";
    }
    else
    {
        btn.Background = Brushes.Red;
        btn.Content = "Background";
    }
}

The following example shows a template that enables a trigger to change the background of a button when it is pressed.

<Button FontSize="16" FontWeight="Bold">Click the Background
  <Button.Template>
    <ControlTemplate TargetType="{x:Type Button}">
      <Border Background="{TemplateBinding Background}">
         <ContentPresenter/>
      </Border>
    </ControlTemplate>
  </Button.Template>

  <Button.Style>
    <Style TargetType="{x:Type Button}">
      <Setter Property="Background" Value="Blue"/>
      <Style.Triggers>
        <Trigger Property="IsPressed" Value="true">
          <Setter Property="Background" Value="Red"/>
        </Trigger>
      </Style.Triggers>
    </Style>
  </Button.Style>
</Button>
