this might work. use javascript/jquery see if browser closing
<script type="text/javascript"> $(function () { $(window).unload(function () { //run ajax webmethod call here }); }); </script> if above doesn't work in body
<body onbeforeunload="closefunction();"> then create method called closefunction , run ajax webmethod there:
function closefunction() { //run ajax webmethod call here } see this link on how ajax webmethod call
