title: Replacing numbers with hashes in WPF when the text is too large
body: <p>I'm looking for a simple, idiomatic method of replicating Excel's visual cue that a number is too large to be displayed in a column. I've got the following xaml:</p>
  
  <pre><code>&lt;ListView.View&gt;
      &lt;GridView&gt;
          &lt;GridViewColumn ... /&gt;
      &lt;/GridView&gt;
  &lt;ListView.View&gt;
  </code></pre>
  
  <p>and what I'd like is if the text in the column is too small to be displayed (i.e. it's clipped), I want to replace the displayed data with '#' characters.</p>
