How to get jQueryui dialog scrollTop to scroll dialog content to top

Try

$("#the_dialog_div").scrollTop("0")

This worked for me!

this is working for me

$(function() 
{
 $( "#tos_dialog" ).dialog({
  title: 'Terms Of Service Agreement',
  autoOpen: true,
  height: 480,
  width: 640,
  modal: true,
  show: "blind",
  hide: "explode",
  buttons: {
   "I Accept": function() {
    $( this ).dialog( "destroy" );
      $( "#login_container" ).dialog( "destroy" );
      window.location.replace('/main.php');
   },
   "I Decline": function() {
      $( this ).dialog( "destroy" );
   }
  },
  open: function() {
    //Solution HERE
    $( ".ui-dialog-content" ).scrollTop(0);
    //End of Solution
  }
});

Try:

setTimeout(function(){
   $('#selector').scrollTop("0");
},100);
