title: Disabling all but one child control in a WPF window
body: <p>I have a bunch of controls on my window.  One of them is a refresh button that performs a cumbersome task on a background thread.</p>
  
  <p>When the user clicks the refresh button, I put the cursor in a wait (hourglass) status and disable the whole window -- <code>Me.IsEnabled = False</code>.</p>
  
  <p>I'd like to support cancellation of the refresh action by letting the user click a cancel button, but I can't facilitate this while the whole window is disabled.</p>
  
  <p>Is there a way to do this besides disabling each control (except for the cancel button) one by one and then re-enabling them one by one when the user clicks cancel?</p>
