Gets or sets the background color for a BulletDecorator control.

Namespace:   System.Windows.Controls.Primitives
Assembly:  PresentationFramework (in PresentationFramework.dll)

Public Property Background As Brush

Property Value

Type: System.Windows.Media.Brush

The background color for the Bullet and Child of a BulletDecorator. The default is null.

The Background property defines the Brush to use to fill the area within the BulletDecorator. For some parent layout elements, the area that is defined for the BulletDecorator may extend beyond its Bullet and Child content. For example, if the BulletDecorator is the single child of a cell in a Grid control, the Background property applies to the whole cell. This occurs because the content in a Grid cell is stretched in all directions to fill the cell, by default. However, if you set the VerticalAlignment property to Center for the BulletDecorator, the Background property only affects the actual content area of the BulletDecorator. Alternatively, you can enclose the BulletDecorator in a Panel element.

The following examples show how to set the Background property on a BulletDecorator control.

Dim myBulletDecorator = New BulletDecorator()
Dim myImage = New Image()
Dim myBitmapImage = New BitmapImage()
myBitmapImage.BeginInit()
myBitmapImage.UriSource = _
   New Uri("pack://application:,,/images/apple.jpg")
myBitmapImage.EndInit()
myImage.Source = myBitmapImage
myImage.Width = 10
myBulletDecorator.Bullet = myImage
myBulletDecorator.Margin = New Thickness(0, 10, 0, 0)
myBulletDecorator.VerticalAlignment = VerticalAlignment.Center
myBulletDecorator.Background = Brushes.Yellow
Dim myTextBlock = New TextBlock()
myTextBlock.Text = "This BulletDecorator created by using code"
myTextBlock.TextWrapping = TextWrapping.Wrap
myTextBlock.HorizontalAlignment = HorizontalAlignment.Left
myTextBlock.Width = 100
myTextBlock.Foreground = Brushes.Purple
myBulletDecorator.Child = myTextBlock
<BulletDecorator  Grid.Row="1" Grid.Column="0" Margin="0,5,0,0"
                  VerticalAlignment="Center" Background="Yellow">
  <BulletDecorator.Bullet>
    <Image Source="images\apple.jpg"/>
  </BulletDecorator.Bullet>
  <TextBlock
    Width="100" 
    TextWrapping="Wrap" 
    HorizontalAlignment="Left"
    Foreground ="Purple">
    A Simple BulletDecorator
  </TextBlock>
</BulletDecorator>
