title: How do you clear a WPF RichTextBox?
body: <p>Whenever I do <code>richtextbox1.Clear()</code> it says the method doesn't exist. And it's pretty much the only solution I get, everywhere I go.</p>
  
  <p>I've tried looking for a <code>Text</code> property, and I've tried to look through the <code>Document</code> property as well, but to no avail.</p>
  
  <p>What I am missing? The box needs to be cleared, like you can do with a <code>textbox.Clear()</code> call.</p>
