title: KeyDown Event not Firing in WPF
body: <p>I am using WPF and VB.Net as Coding Language.</p>
  
  <p>When I press any keys, on some keys like all alphabetical keys keyDown Event Fires nicely, But If I use arrow keys then keyDown event Does not Fire. On WPF I don't know how to do it. There was same problem in winForms too. But there was KeyPress event which worked perfectly.</p>
  
  <p>I have searched on google but every where I got the same answer.</p>
  
  <pre><code>this.KeyPreview = True;
  </code></pre>
  
  <p>But I am using VB.Net. I cant find any <code>this</code> object in VB.Net</p>
