WPF Textblock, linebreak in Text attribute

Question

Is there a way to have \n make a line break in a TextBlock?

<TextBlock Text="line1\nLine2" />

Or is there a better way to force a middle line break, inside the Text attribute?

<LineBreak />

This doesn't work for me, it needs to be the value of the Text attribute, because the text string is being set from an outside source.

I'm familiar with LineBreak but it's not the answer I'm looking for.

in xaml you have to use control characters <TextBlock Name="txtBlock" Text="Line1&#10;Line2" />, if you want to use the \n character it only works from code behind txtBlock.Text = "line1\nline2"; – Chromoprotein

&#10; works fine in xaml. Thank you JJ_Coder4Hire ! – Postimpressionism

Answer 1

I know this is ressurecting an old question, but I had the same problem. The solution for me was to use HTML encoded line feeds (
).

Line1
Line2

Looks like

Line1
Line2

@Knasterbax if the text is specified as the content between <TextBlock> and </TextBlock> then yeah, you'll need <LineBreak/>. 
 works inside the Text attribute: <TextBlock Text="..." /> – Baghdad

"&#10;" worked for me. I did not need the "&amp;" as mentioned though. This method will also work when setting the text like so: <Setter Property="Text" Value="Line 1&#10;&#10;Line 2" /> – Bolin

The "outside source" should rather use Environment.NewLine. – Parolee

Answer 2

Try this:

<TextBlock>
    line1
    <LineBreak />
    line2
</TextBlock>

Haven't tried this directly but off the top of my head you could try xml:space="preserve" and then embed the line break in the Text property directly. – Loram

Capitalization matters. It's <LineBreak />. – Mazy

Answer 3

The easiest way is

<TextBlock> blabla <LineBreak /> coucou <LineBreak /> coucou 2 </TextBlock>

So you just write XAML code, and the <LineBreak /> has exactly the same meaning the
in HTML or the "\n" in C#.

Scott I don't understand your comment. – Buerger

The problem is that <LineBreak/> doesn't work on Windows XP. It may also have something to do with the .NET version installed. There are no exceptions and no errors other than the visual elements don't display correctly. – Tyrolienne

@Tyrolienne If the problem was the .NET version why didn't you just install an update? I don't care about old libraries if you can update them without any trouble. – Parolee

Answer 5

How about breaking the line into two tags?

<StackPanel>
    <TextBlock Text="Line1" />
    <TextBlock Text="Line2" />
</StackPanel>

Answer 6

Correct way to use it may be the following :

<TextBlock>  
    <Span>text1</Span>  
    <LineBreak/>  
    <Span>text2</Span>  
</TextBlock>

Aside from the fact that that doesn't answer the question (outside source) - what's "more correct" with Span than without? – Parolee

Answer 7

<LineBreak/> will not work if it is inside a collection such as Grid or StackPanel. In such cases the following would work as shown:

Quintet

I tried this as the content for a RadioButton. Everything seemed to work fine until I ran the program on Windows 7. On windows 7 the button was centered vertically between the two lines. Windows 10 aligns the button top the top by default. While Windows 10 would honor the VerticalContentAlignment property, Windows 7 ignores it. I had to use the LineBreak solution. – Dorothadorothea

@Dorothadorothea How can a button get between 2 text blocks that are it's content? And why did you even use this solution here? A RadioButton is no collection, is it? Could you please show your code? – Parolee

@TheincredibleJan It has been 4 years, so no, I don't have the code. It probably looked something like this: <RadioButton><StackPanel><TextBlock>Line 1</TextBlock><TextBlock>Line 2</TextBlock><TextBlock>Line 3</TextBlock></StackPanel></RadioButton>. I also don't have a Windows 7 machine to test with either, but I would presume that on Windows 7, the button always aligned with 'Line 2' regardless of any alignment settings – Dorothadorothea

Answer 8

The Best way that worked for me for multiple lines in the same Textblock is:

<TextBlock>  
    text1  
    <LineBreak/>  
    text2  
</TextBlock>

Make sure to not use TextWrapping="Wrap". Use TextWrapping="NoWrap" or use nothing.

Answer 9

  <HyperlinkButton 
        Content="Apply and restart this pplication!&#10;&#13;Note that modifying these settings requires the application to be restarted."   />

Answer 10

If you are binding TextBlock's Text, none of the other answers work. Simply add '\n' to the binding text to where you want to break.

Henceforward

Answer 11

this 
 did not work for me, when I used binding. But this works:

$"first line {Environment.NewLine} second line"

Answer 12

This also works fine:

<TextBlock>
    <Run Text="My nice text"/>
    <LineBreak/>
    <LineBreak/>
    <Run Text="After some linebreaks, I'm back!"/>
</TextBlock>

Answer 13

I'm late to the party but .. this is more or less how I did it ,(mind my ItemSources are plain strings, not formatted , and I didn't need to 'convertBack' anything)

public class SpaceToLineBreakConverter : IValueConverter
{   
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {            
        return (!String.IsNullOrEmpty(value as string)) 
        ? new Regex(@"\s").Replace(value as string, "\n") 
        : value;            
    }

    public object ConvertBack(object value, Type targetType, object parameter,System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

Answer 14

I was having a similar problem and wanted to bind a String of xaml markup to a TextBlock. Essentialy storing the declarative markup inside a TextBlock in a string for later use.

This is how I did: I subclassed the TextBlock to make the InlineCollection bindable and wrote a Converter between the string and an InlineCollection(or actually a generic list of Inlines.)

Answer 15

just use the AccessText control. you can use it like a label and you have the property TextWrapping="WrapWithOverflow"

eg.

Mine is like that and it's working fine. Also, you don't have any problems on changing the text dinamically.

Answer 16

This also works fine.

Using this method we can modify the text properties in each line as we required.

<TextBlock>
    <StackPanel>
        <TextBlock FontSize="12" FontWeight="Bold" >My Text One</TextBlock>
        <TextBlock FontFamily="Times New Roman" FontStyle="Italic">
            - My Text Two
        </TextBlock>
    </StackPanel>
</TextBlock>
