title: Silverlight Issue styling Combobox
body: <p>I'm trying to style a combobox in silverlight and am running into an issue. Please look at the attached image.</p>
  
  <p><img src="https://i.stack.imgur.com/b8ad0.jpg" alt="enter image description here"></p>
  
  <p>Look at what the red arrow is pointing to. I'm unable to figure out what I should change to get that light blue to change. What do I do?</p>
