Sorry this is not possible, what you want here.

As i have mentioned in my last post that you can make AJAX request but that is not possible in all the browsers

Every browser behaves differently, Like you can make an AJAX request to the server(either HTTPHandler or Service and not the WebMethod on the same page) from Internet Explorer from unload event but this will not work in Google chrome. I tried to make an AJAX request to an HTTP handler from unload event on Internet Explorer and it is working fine.

For Making AJAX Request i have used this code(AJAX request using jQuery).

function HandleClose() {
alert('Window is to be closed.');
$.ajax({
url: "/Default.AbondonSession",
data: {},
dataType: "json",
success: function (msg) {
alert(msg.d);
}
});

}

If you don't know hot to create HTTP handler you can refer a section(For Creating HTTP Handler) in one of my post http://www.c-sharpcorner.com/UploadFile/25c78a/jquery-ui-autocomplete/

I haven't checked but it will definitely behave differently in Safari and Firefox.

this is not a full proof solution as it is browser dependent and you can't change the browser behaviour.

What i can understand is that you want to call a server side method on page unload. Sorry to say but it is not possible as Web is working on stateless model. Unload is the last event which is called before the page closes, you can show alert in javascript before page close but you cant stop the page from closing so that is why your server side method is not getting fired.

you can make an AJAX request but i am sure that you will never get the response from that request, because till the time you can get the response the page on the client side is actually disposed.
