When I have TextBlock. Run Text = "(" Run Text={Binding IncomeLoss} Run Text=")" in a Page it comes out looking ok,
but when I have the same thing inside a ControlTemplate that I apply to a class that derives from Control, there is extra space after each character like "( 100 ) ".
I read that ControlTemplate is a barrier to style inheritance, but how do I guess what exactly style parameter is the one missing that is usually inherited by the Textblock on a Page?
Make sure that you have put all Run elements on the same line in the ControlTemplate.
There is a difference in output between this:
<TextBlock><Run Text = "(" /><Run Text="{Binding IncomeLoss}"/><Run Text=")"/></TextBlock>
...and this:
<TextBlock>
<Run Text = "(" />
<Run Text="{Binding IncomeLoss}"/>
<Run Text=")"/>
</TextBlock>

I would bind a string property to text property like this: Text="{Binding propertyName}.
I also want to append a hardcoded string to this like Text="{Binding propertyName} appendedName. How to do this?
Text="{Binding propertyName,StringFormat='Your property is: {}{0}'}"
You could use Run Text:
<TextBlock>
<Run Text="{Binding YourBinding}"/>
<Run Text="Suffix"/>
</TextBlock>
If you want to use it like this several times I would recommend a TemplatedControl where you have a Suffix DependencyProperty and a Text DependencyProperty.
You should create new property that returns text + appendedName.
Another way is to use several text blocks.
When would I use the Text attribute of the <TextBlock> and when should I put my text in the content of the <TextBlock>?
<TextBlock Text="Example Text" />
vs.
<TextBlock>Example Text</TextBlock>
The former can be bound, whilst the latter is particularly useful when combining Runs:
<TextBlock Text="{Binding SomeProperty}"/>
<TextBlock>
<Run>You have </Run>
<Run Text="{Binding Count}"/>
<Run>items.</Run>
</TextBlock>
The use of the Text property has become common as a result of previous versions of the Xaml parser but the placing the text as content is more natural especially if you have a background in HTML.
The fact the many TextBlocks either have simple short chunks of literal text in or are bound. Would tip the balance IMO to using the Text property. In addition any globalisation that may come along latter may end with those literals being replaced by bindings as well.
I'm trying to make a Hyperlink that contains text with super- and/or subscripts. I've found two ways to do this, and both of them suck.
Solution #1: use Typography.Variants. This gives a terrific superscript... for some fonts.
<StackPanel>
<TextBlock FontFamily="Palatino Linotype" FontSize="30">
<Hyperlink>R<Run Typography.Variants="Superscript">2</Run></Hyperlink>
(Palatino Linotype)
</TextBlock>
<TextBlock FontFamily="Segoe UI" FontSize="30">
<Hyperlink>R<Run Typography.Variants="Superscript">2</Run></Hyperlink>
(Segoe UI)
</TextBlock>
</StackPanel>
(source: excastle.com)
Looks beautiful in Palatino Linotype; but for fonts that don't support variants, it's simply ignored, no emulation is done, and the text is full-size, at-baseline, 100% normal. I would prefer to allow my end-users to select the font they want to use, and still have super/subscripts work.
Solution #2: use BaselineAlignment. This raises or lowers the text appropriately, though unlike solution #1, I have to decrease the font size manually. Still, it's effective for all fonts. The problem is the Hyperlink's underline.
<TextBlock FontSize="30" FontFamily="Palatino Linotype">
<Hyperlink>
R<Run BaselineAlignment="Superscript" FontSize="12pt">2</Run>
</Hyperlink>
</TextBlock>
The underline is raised and lowered along with the text, which looks pretty wretched. I'd rather have a continuous, unbroken underline under the whole Hyperlink. (And before anyone suggests a Border, I'd also like the Hyperlink to be able to word-wrap, with all of the words underlined, including the first row.)
Is there any way to make superscript and subscript work in WPF, in any font, without looking laughably bad when underlined?
If the hyperlink isn't going to wrap to more than one line, then embedding another TextBlock can work:
<TextBlock FontSize="30" FontFamily="Palatino Linotype">
<Hyperlink>
<TextBlock>
R<Run BaselineAlignment="Superscript" FontSize="12pt">2</Run>
</TextBlock>
</Hyperlink>
</TextBlock>
This will give a solid hyperlink under the Hyperlink's child, which means an unbroken hyperlink:
However, if the embedded TextBlock needs to wrap to multiple lines, you'll only get one underline under the entire wrapped paragraph, rather than underlining each line of text:
(source: excastle.com)
If you can put a TextBlock only around a short bit of content that needs superscripts -- e.g., around just the R^2 in the above example -- and leave the rest of the text parented to the hyperlink, then you get underlining as normal. But sometimes that's not practical, so it's something to watch out for.
You can use the superscript unicode characters (e.g. http://www.fileformat.info/info/unicode/char/b2/index.htm)
Like this:
<TextBlock FontSize="30" FontFamily="Segoe UI">
<Hyperlink>
Apply R² Calculation
</Hyperlink>
</TextBlock>
Result:
Obviously this will not work unless what you are super scripting actually has a unicode superscript character.
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.
Try this:
<TextBlock>
line1
<LineBreak />
line2
</TextBlock>
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
For more of the HTML encoded characters check out w3schools
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#.
<LineBreak/>

How about breaking the line into two tags?
<StackPanel>
<TextBlock Text="Line1" />
<TextBlock Text="Line2" />
</StackPanel>
<LineBreak/> will not work if it is inside a collection such as Grid or StackPanel.
In such cases the following would work as shown:
Correct way to use it may be the following :
<TextBlock>
<Span>text1</Span>
<LineBreak/>
<Span>text2</Span>
</TextBlock>
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.
<HyperlinkButton
Content="Apply and restart this pplication!
Note that modifying these settings requires the application to be restarted." />

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.
this did not work for me, when I used binding. But this works:
$"first line {Environment.NewLine} second line"
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();
}
}
This also works fine:
<TextBlock>
<Run Text="My nice text"/>
<LineBreak/>
<LineBreak/>
<Run Text="After some linebreaks, I'm back!"/>
</TextBlock>
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.)
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.
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>
