How can i get same functionality in windows forms as in the next example. When i have two links one beneath, and when i click first link a panel is visibleunder it and next link is shifted. When i click again the panel is invisible and second link shifted back.

  <script type="text/javascript">
   function toggleDivState(divName)
   {
      var ctl = window.document.getElementById(divName);
      if (ctl.style.display == "none")
         ctl.style.display = "";
      else
         ctl.style.display = "none";
   }
  </script>

<a href="javascript:toggleDivState('poll<%# Eval("ID") %>');">
<div style="display: none;" id="poll<%# Eval("ID") %>">
