title: Display format string, int to percent
body: <p>I have some integer values (between 1 and 100) and I want to use them in a progress bar, that has a DisplayFormatString property. </p>
  
  <p>I also want to have the percent symbol '%' in the output string. </p>
  
  <p>The problem is that by using the symbol, it automatically multiplies my value with 100, and it shows my values like 3300% when I wanted them 33%. How may I overcome this?</p>
  
  <pre><code>DisplayFormatString="0%"
  </code></pre>
