function myFunction() {
    alert('hello');
    var fname = document.getElementById('<%=hidden.ClientID%>').value;
    alert(fname);
    var mapOptions =
                {
                    zoom: 13,
                    mapTypeId: google.maps.MapTypeId.ROADMAP
                }
    var infowindow = new google.maps.InfoWindow();
    var map = new google.maps.Map(document.getElementById('displayMap'), mapOptions);

    $.ajax({
        type: "GET",
        url: "Location\\" + fname + "",
        dataType: "xml",
        success: function (xml) {
            $(xml).find("Location").each(function () {
                Loc = $(this).find("Loc_Name").text();
                Lat = $(this).find("Latitude").text();

                var loc = new google.maps.LatLng(Lat, Long);
