title: Return to default values PowerBuilder 11
body: <p>I have a DataWindow object with these three columns:</p>
  
  <ul>
  <li>status - which is a checkbox</li>
  <li>criteria - which is a dropdownDW</li>
  <li>another </li>
  </ul>
  
  <p>When status is 1 (checked) then <code>criteria.Protect='0'</code>. If the user chooses from the criteria list "another criteria", then <code>another.Protect='0'</code> and the user can write whatever he wants.</p>
  
  <p>The problem is when the user changes his mind and uncheck the status. 
  The criteria and the another column have the last values he chose/wrote before. How can I reset the dropdownDW or how can I have the default values back?</p>
  
  <p>In the itemchange event I have this:</p>
  
  <pre><code>choose case dwo.name
    case "status"
      if  data ='0' then
        dw_list.modify("criteria.Protect='1'")
        dw_list.modify("another.Protect='1'")
      else
        dw_list.modify("criteria.Protect='0'")
      end if
  </code></pre>
