currently js code is outside the form tag but it is not working inside the form tag either.
here is code

What I have tried:

ASP.NET

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<head runat="server">
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key= xxxxXfuVqTQRTy5AmZx9D3pHjkfHW4&sensor=false">
</script>
    <title></title>
</head>
<body>
<div id="map">
<script type="text/javascript">
    function InitializeMap() {
        var latlng = new google.maps.LatLng(-34.397, 150.644);
        var myOptions = {
            zoom: 8,
            center: latlng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        var map = new google.maps.Map(document.getElementById("map"), myOptions);
    }

    window.onload = InitializeMap;
</script>
<form id="form1" runat="server">    
    
    </form>
    </div>
    
</body>
</html>

Your html is messed up. Move inside the form which also means to move the closing div inside the form tag as well. then move the script into your head.

It's quite possible that the onload event will fire before the maps script has finished loading.

You also need to set an explicit height for the container element.
