There are no possibility to run function from aspx page directly via url.

Try the following:

Change your ajax request as below:

$.ajax({
     type: "POST",
     url: 'About.aspx',
     data: '{"method":"updatingdatabase","username":"' + col1 + '","password":"' + col2 + '","age":"' + col3 + '","city":"' + col4 + '","id":"' + idlast + '"}',
     contentType: "application/json; charset=utf-8",
     dataType: "json",
     success: function (data) {
                      var x = data.d;// i am trying to store the return data into a local variable

     },
     error: function (e) {

     }
 });

Update Page_Load handler in your page:

protected void Page_Load(object sender, EventArgs e)
{
    if (!String.IsNullOrEmpty(Request["method"]) && String.Compare(Request["method"], "updatingdatabase", true) == 0)
    {
        UpdatingDatabase(); //run the method
    }
}

try this

data: '{"method":"updatingdatabase","username":"' + col1 + '","password":"' + col2 + '","age":"' + col3 + '","city":"' + col4 + '","id":"' + idlast + '"}',

instead of

 url: 'About.aspx',
     data: '{"method":"updatingdatabase","username":"' + col1 + '","password":"' + col2 + '","age":"' + col3 + '","city":"' + col4 + '","id":"' + idlast + '"}',

and call function in pageload
