“Silverlight Tip of the Day #58 – Text Wrapping and Line Breaks in TextBlocks”

TextBlocks are a great control to use in Silverlight to display read only text. In Tip of the Day #45 I covered the basic usage of TextBlocks including formatting and text runs.

For this tip I would like to show you how to make a TextBlock with wrapping text and line breaks.

To make a TextBlock wrap its text you will need to set TextWrapping ="Wrap" on the TextBlock. The following example below shows a TextBlock in a ContentControl that is only 100 pixels wide. With TextWrapping set to “Wrap”, the TextBlock will wrap to a new line each time its contents reach 100 pixels in width.

XAML:

        A lie can travel half way around the world while the truth is putting on its shoes.        

        --Mark Twain
    &lt;/TextBlock&gt;
&lt;/ContentControl&gt;

</Canvas>

…

As you may notice the text above does not include any of the line breaks seen in the XAML. To insert a line break all you need to do is insert a <LineBreak> tag within the text.

Example:

<Canvas Margin="10"> <ContentControl Width="100"> <TextBlock TextWrapping="Wrap"> A lie can travel half way around the world while the truth is putting on its shoes. <LineBreak></LineBreak> <LineBreak></LineBreak> --Mark Twain </TextBlock> </ContentControl>

</Canvas>
