TextBlock

The TextBlock is a read-only label for the display of text. It can display multiple lines, and features full control over the font used.

Useful Properties

You will probably use these properties most often:

Property	Description
Text	The text to display.
FontSize	The size of the font.
FontWeight	The weight of the font. Default is normal, options include Bold.
FontStyle	A style to apply to the lettering. Default is normal, options include Italic.
TextDecorations	A line decoration to apply to the lettering. Default is none, options include Underline, Strikethrough, Baseline and Overline. To apply more than one at the same time, list the options with spaces between.
xml:space	xml:space="preserve" directs the XML parser to preserve line breaks and whitespace for content assigned to TextBlock else it is stripped by default.

Example

This example demonstrates using multiple TextBlock controls to show a heading, single line containing extra space, and multi-line displays.

<StackPanel Margin="20">
  <TextBlock Margin="0 5" FontSize="18" FontWeight="Bold">Heading</TextBlock>
  <TextBlock Margin="0 5" FontStyle="Italic" xml:space="preserve">This is  a single line.</TextBlock>
  <TextBlock Margin="0 5" xml:space="preserve">This is a multi-line display
that has returns in it.
The text block respects the line breaks
as set out in XAML.</TextBlock>
</StackPanel>

The styling works in the preview pane:

Inlines

Text inlines allow diverse formatting of text and controls inside of a single TextBlock. While TextBlock.Text is routinely used to display a single uniformly formatted text, its child Content allows for a collection of inlines.

Run

The Run inline represents a contiguous run of uniformly formatted text.

<Style Selector="Run.activity">
	<Setter Property="Foreground" Value="#C469EE" />
	<Setter Property="FontStyle" Value="Italic" />
	<Setter Property="TextDecorations" Value="Underline" />
</Style>

<TextBlock>
	<Run Text="Your name is" />
	<Run FontSize="24" FontWeight="Bold" Foreground="Orange" Text="{Binding Name}" />
	<Run Text="and your favorite activity is" />
	<Run Classes="activity" Text="{Binding Activity}" />
</TextBlock>

LineBreak

The LineBreak inline forces a line break.

<TextBlock>
    This is the first line and<LineBreak />here comes the second
</TextBlock>

Span

The Span inline allows grouping of inlines, including non-text inlines. While Span can apply its own text formatting, there are a few predefined formatting inlines derived from Span: Bold, Italic, and Underline. Users may also derive from Span to create their own formatting instead of using styles.

<TextBlock>
	This text is <Span Foreground="Green"> green with <Bold>bold sections,</Bold>
	<Italic>italic <Span Foreground="Red">red</Span> sections,</Italic>
	some
	<Run FontSize="24"> enlarged font runs,</Run>
	and</Span>
	back to the original formatting
</TextBlock>

InlineUIContainer

The InlineUIContainer allows any Control to be included as an inline.

<TextBlock ClipToBounds="False" FontSize="32" TextWrapping="Wrap">
    🚀 This <Span BaselineAlignment="TextTop">example</Span> shows the <Bold>power</Bold> of
    <InlineUIContainer BaselineAlignment="Baseline">
        <Image Width="32" Height="32" VerticalAlignment="Top" Source="/Assets/avalonia-logo.ico" />
    </InlineUIContainer>
    in creating rich text displays with
    <InlineUIContainer>
        <Button Padding="0,8,0,0">
            <TextBlock ClipToBounds="False" FontSize="24" Text="👍👍🏼👍🏽👍🏾👍🏿" />
        </Button>
    </InlineUIContainer>
    inline controls 📈
</TextBlock>
