  <ol>
  <li><p>The dropdown list will bind the following options</p>
  
  <p>i) internetwork
  II) lan
  iii) none</p></li>
  </ol>
  
  <p>Question</p>
  
  <ol>
  <li>if the lan item in dropdownlist is selected from the row one of list view, i would like to make other other dropdownlist item's item must become none.</li>
  </ol>
  
  <p>Can this be done using WPF UI or have to use only data model for this?</p>
