Try using ajax call for setting the session value:-

JS:-

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"> </script>
<script type="text/javascript">
    var TempSession = '<%= Convert.ToInt32(Session["Status"]) %>';
    if (TempSession == 6) {
        alert(TempSession);
        $.ajax({
            type: 'POST',
            url: 'WebForm1.aspx/SetValue',
            data: '{ val:1 }',
            contentType: 'application/json; charset=utf-8',
            dataType: 'json',
            success: function (msg) {
                alert("New Session value is " + msg.d);
            }
        });
    }

</script>

In your code behind file:-

[WebMethod]
public static string SetValue(string val)
{
    HttpContext.Current.Session["Status"] = val;
    return HttpContext.Current.Session["Status"].ToString();
}
