Preserving whitespace in Run element

Question

When formatting a paragraph as so -

<RichTextBlock>
<Paragraph xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'>

<Run></Run> 

<InlineUIContainer><TextBlock >Words here</TextBlock></InlineUIContainer> 

<Run xml:space="preserve"> </Run> 

<InlineUIContainer><TextBlock>More words here</TextBlock></InlineUIContainer> 

<Run xml:space="preserve"> Lastly some words here</Run>

</Paragraph>
</RichTextBlock>

The <Run> element containing a single space is never displayed and ignore the space=preserve property. However the last run with a leading space is displayed correctly.

How can I get a run containing a single space to display ?

Answer 1

Here is the workaround:

<Run xml:space="preserve" Text="     " /> 

Happy New Year!

Answer 2

Thanks for the answer but this still has the exact same issue.

Answer 3

Check this.  I can really reproduce the problem. But this is maybe because I am using a Silverlight project for Windows Phone.

<TextBlock
       TextWrapping="Wrap" >
       <Run>This is a simple sample.</Run>
       <LineBreak/>
       <Run xml:space="preserve">    </Run>   <!-- this line has no effect -->
       <Run xml:space="preserve">You can put any content you want here...</Run>
       <LineBreak/>
       <Run xml:space="preserve" Text="     " />  <!-- this line is OK -->
       <Run xml:space="preserve">You can put any content you want here...</Run>                        
</TextBlock>

After some experimentation it seems like it is only an issue when the run is contained between two InlineUIContainers. Any ideas why? or a workaround?

I.e

<RichTextBlock TextWrapping="Wrap" HorizontalAlignment="Center" >
<!-- Not working -->
            <Paragraph xml:space="preserve"><InlineUIContainer><TextBlock>first part</TextBlock></InlineUIContainer><Run xml:space="preserve" Text="     " /><InlineUIContainer><TextBlock>second part</TextBlock></InlineUIContainer></Paragraph>
<!-- working -->
            <Paragraph xml:space="preserve"><Run>First part</Run><Run xml:space="preserve" Text="     " /><InlineUIContainer><TextBlock>second part</TextBlock></InlineUIContainer></Paragraph>
</RichTextBlock>
