  <p>I want the Change Password button in same format and style as help and contact us,but when i add actionbutton OR actionlink,not able to get the same format and alignment respectively.</p>
  
  <p>Alternatively if i add a tagname(Change password it has the same format,but i want to link it with observe function further</p>
