While closing Browser need to call a method in c#. OR need to reset a ISconnected to zero in DB table

What I have tried:

JS 

<pre>    window.onbeforeunload = function (e) {
// Your logic to prepare for 'Stay on this Page' goes here 
if((window.event.clientX<0) || (window.event.clientY<0))
    {
      UpdateLoginPassword();
    }
};

C#

public void UpdateLoginPassword(object sender, EventArgs e)
    {
            //To update Isconnetedflag flag to 0
            Quadra.Suite.Essential.UserManagement.ISYSUserService SYSUserService = serviceUtil.GetServiceProxy<Quadra.Suite.Essential.UserManagement.ISYSUserService>();
            SYSUserService.UpdateIsConnected(Convert.ToInt16(LOGIN_DETAILS.LoginUserID));
    }

You don't know when the browser is closed, and what if I don't close it but hibernate my machine, or simply leave it open for 3 days? The web is stateless and you should architect your sites so that they obey that and are stateless themselves. You will never know if the user is there or not.

you can do this with ajax that calls a web service or web api function.

<script type="text/javascript">


<pre>if((window.event.clientX<0) || (window.event.clientY<0))
    {
$.ajax({
         type: "POST",
         url: 'YOURWEBSERVICENAMEHERE.asmx/UpdateLoginPassword',
         data: "",
         contentType: "application/json; charset=utf-8",
         dataType: "json",
         success: function (msg) {
              alert('success');
         },
         error: function (e) {
              alert('fail');
         }
       });
    }
};
</script>
