TextBlock.FontWeight Property

 

Gets or sets the top-level font weight for the TextBlock.

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

Public Property FontWeight As FontWeight

Property Value

Type: System.Windows.FontWeight

A member of the FontWeights class specifying the desired font weight. The default is determined by the SystemFonts.MessageFontWeight value.

Any FontWeight settings on child elements override this top-level setting.

For a list of valid values of font weights, see the FontWeights class.

This dependency property also has an attached property usage. In XAML, the usage is <object TextBlock.FontWeight="value".../>, where object is an object element (typically a flow element) contained within a TextBlock, and value is one of the string-format values of a property of the FontWeights class. In code, the attached property usage is supported by GetFontWeight and SetFontWeight. The attached property usage is not common, because most elements that can be contained in a TextBlock support an analogous nonattached FontWeight property, which the TextBlock uses for rendering.

The following example shows how to set the FontWeight attribute of a TextBlock element.

<TextBlock 
  Name="textBlock"

  Background="AntiqueWhite" 
  Foreground="Navy" 

  FontFamily="Century Gothic"
  FontSize="12"
  FontStretch="UltraExpanded"
  FontStyle="Italic"
  FontWeight="UltraBold"

  LineHeight="Auto"
  Padding="5,10,5,10"
  TextAlignment="Center"
  TextWrapping="Wrap"

  Typography.NumeralStyle="OldStyle"
  Typography.SlashedZero="True"
>
  <Run Background="LightGreen">Text run 1.</Run>
  <LineBreak/><Run Background="LightBlue">Text run 2.</Run>
  <LineBreak/><Run Background="LightYellow">Text run 3.</Run>
</TextBlock>

The following example shows how to set the FontWeight property programmatically.

Dim textBlock As New TextBlock(New Run("A bit of text content..."))

textBlock.Background = Brushes.AntiqueWhite
textBlock.Foreground = Brushes.Navy

textBlock.FontFamily = New FontFamily("Century Gothic")
textBlock.FontSize = 12
textBlock.FontStretch = FontStretches.UltraExpanded
textBlock.FontStyle = FontStyles.Italic
textBlock.FontWeight = FontWeights.UltraBold

textBlock.LineHeight = Double.NaN
textBlock.Padding = New Thickness(5, 10, 5, 10)
textBlock.TextAlignment = TextAlignment.Center
textBlock.TextWrapping = TextWrapping.Wrap

textBlock.Typography.NumeralStyle = FontNumeralStyle.OldStyle
textBlock.Typography.SlashedZero = True
