title: Convert my full path file name into FileInfo.name in XAML binding
body: <p>This is my model:</p>
  
  <pre><code>public class Data
  {
      string fileName;
  }
  </code></pre>
  
  <p>And inside my <code>XAML</code> binding:</p>
  
  <pre><code>&lt;GridViewColumn Width="470" Header="File name" DisplayMemberBinding="{Binding FileName}" /&gt;
  </code></pre>
  
  <p>Now i don't want to see the whole path of my file but only the <code>File Name</code>, i know i can add another <code>class member</code> and put it but i wonder if i can change this inside my <code>DisplayMemberBinding</code></p>
