title: TextTrimming with Ellipsis and a Colon
body: <p>This is a relatively simple question:</p>
  
  <p>I can trim a text with ellipsis using this:</p>
  
  <pre><code>&lt;TextBlock Text="{Binding}" TextTrimming="CharacterEllipsis"/&gt;
  </code></pre>
  
  <p>it would give me something along the lines of:</p>
  
  <p>"This sentence is too long"</p>
  
  <p>=></p>
  
  <p>"This sentence i..."</p>
  
  <p>That's all great and dandy, but what I actually want is this:</p>
  
  <p>"This sentence ...:" / "This sentence...:"</p>
  
  <p>What I'm looking for is a colon after the ellipses.  Is there a simple way to achieve this?</p>
  
  <p>EDIT:</p>
  
  <p>sorry for the confusion.</p>
  
  <p>I want to change the default ellipsis string from '...' to '...:'.  As well, I'm going to include a colon in the text string itself.  This way, I'll always have the colon displayed.  As well, everything should be on one line in every situation.</p>
  
  <p>here are a couple of results that are acceptable:</p>
  
  <p>short enough:</p>
  
  <p>way too l...:</p>
