title: Alternative to WPF combo box dropdownstyle
body: <p>In system.windows.forms, a combo box had a DropDownStyle.  Unfortunately, I hate the style of a readonly combo box in WPF, and there is no longer the ability to set the DropDownStyle/FlatStyle to is there an easy way to simply never use the ugly gray "button"-looking combo box and always use the appearance as though it is a text box with a drop down arrow?  </p>
  
  <p>I hope I'm making sense...  Accomplishing this seems way more difficult than it should be.  </p>
  
  <p>Thank you!</p>
