this listener do:

listeners: {                                 keypress: function(textfield, e, options) {                                     if (e.keycode === 13) {                                         var form = this.up("form").getform();                                         if (form.isvalid()) {                                             ext.getcmp("<%=submitbtnid%>").disable();                                             form.standardsubmit = true;                                             form.method = "post";                                             form.submit();                                          }                                     }                                 }                             }
