JQuery dialog not opening second time on click -

-

this code open jquery dialog. works first time (gets opened) not second time (not opening). similar question asked here not working me 

function loadgridview(id, row) {    var dlg = jquery('#edit').load('edit.aspx');      dlg.dialog({      autoopen: false,      modal: true,      show: 'slide',      close: 'slide',      width: 400,      height: 160,      buttons: {        "cancel": function() {          dlg.dialog("close");        }      }    });          dlg.dialog("open");  }

your dlg scope not exist when try open second time, need store globally 

// global var hold dlg var dlg;  $(document).ready(function() {   // element , store in dlg global var scope may retain   dlg = $("[id$='edit']");     dlg.dialog({     autoopen: false,     modal: true,     show: 'slide',     close: 'slide',     width: 400,     height: 160,     buttons: {       "cancel": function() {         dlg.dialog("close");       }     }   });  });
