A FontFamily object specifying the preferred font family, or a primary preferred font family with one or more fallback font families. The default is the font determined by the MessageFontFamily value.

Attributes: LocalizabilityAttribute

Examples

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

TextBlock textBlock = 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;

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

Remarks

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

When multiple families are specified, the second and subsequent font families serve as fallback families to be used in cases where the primary font family is unavailable or not applicable.

This property specifies a preference only. If the specified font family is not available, the TextBlock silently falls back to the font determined by the MessageFontFamily value.

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

XAML Attribute Usage

<object FontFamily="fontFamilyName"/>
- or -
<object FontFamily="fontFamilyNamesList"/>
- or -
<object FontFamily="fontFamilyFolderReference"/>
- or -
<object FontFamily="fontFamilyUriReference"/>

XAML Values

fontFamilyName A string specifying a font family name. For example, "Arial" or "Century Gothic".

fontFamilyNamesList A string specifying multiple font family names, each separated by a comma (any white space following a comma is ignored). The first font family specified serves as the primary font family; subsequent font families serve as fallback families to be used in cases where the primary font family is unavailable or not applicable. For example, "Arial, Century Gothic" specifies Arial as the primary font family, with Century Gothic as the fallback font family.

fontFamilyFolderReference A string specifying a folder containing the font, along with a font family name. The folder and font family name are delimited by a # character. The folder reference may be absolute, or relative. For example, "Custom Fonts\#My Custom Font".

fontFamilyUriReference A string specifying a uniform resource identifier (URI) for the font, along with a font family name. The URI and font family name are delimited by a # character. For example, "http://MyFontServer/Fonts/#My Custom Font".
