To call the parameterize void function/method of server side from client side

You can define this method in an .asmx web service and call it via jQuery AJAX. The AJAX client side would look like this:

var val = <value for="" eleid="">
jQuery.ajax({
                url: "service.asmx/CreateDivSize",
                type: "POST",
                data: '{"eleId":"' + val + '"}',
                contentType: "application/json; charset=utf-8"
            }).done(function (ds) {
            });</value>

You can execute this AJAX request on any event you want, but please note that I have not had a great luck using JQuery AJAX with ASP.NET because AJAX calls like these don't seem to update the view-state correctly so any ASP.NET postback that depends on the change to viewstate, for e.g. UpdatePanels, might behave weirdly.

Please make sure you take care using these 2 things together.
