title: WPF listbox. Skip underscore symbols in strings
body: <p>I have some WPF ListBox which is dynamically populating with items. Something like this :</p>
  
  <pre><code>ListBox.Items.Add
  (new ListBoxItem { Content = new CheckBox { IsChecked = true, Content = "string_string"} );
  </code></pre>
  
  <p>The problem is with checkbox content. It's showing on GUI like "stringstring"...
  How to escape the "_" symbols ? (I get strings dynamically)</p>
