title: Dropdown a combobox list automatically when item selected by mouse
body: <p>I need to reopen combobox list when a special item selected from the list. In this code I assume combo list will reopen when an item selected. It works if you use keyboard but I've got problem with the mouse.</p>
  
  <pre><code>        private void cbPredefinedReports_SelectionChanged(object sender, SelectionChangedEventArgs e)
          {
              cbPredefinedReports.IsDropDownOpen = true;
          }
  </code></pre>
  
  <p>How can I drop the list again when a user clicks an item?</p>
