Use Hidden variable to maintain visible / Insvisible flag. Also when ever postbacks check for flag and do display:none or display:block in the javascript

$(document).ready(function () {
  var manager = Sys.WebForms.PageRequestManager.getInstance();
  manager.add_endRequest(endRequest);
  manager.add_beginRequest(OnBeginRequest);

  if(hdnShowflag == true)
  {
    display:block
  }
  else
  {
    display:block
  }
});

function OnBeginRequest(sender, args) {
  if(hdnShowflag == true)
  {
    display:block
  }
  else
  {
    display:block
  }
}

function endRequest(sender, args) {
  if(hdnShowflag == true)
  {
    display:block
  }
  else
  {
    display:block
  }
}

Solution 2

If you are using session management, store the state of the variable in a session and load it once the page reloads.
If you are unaware about state management, you might want to read about it in a book or msdn.
