To implement the Google Maps in Asp.Net with Demo you need to follow the below steps :
Step1 :
Create a new Asp.net website in Visual Studio and write the following html code in the design part of the Default.aspx page.
Source Code :
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
Step2:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script language="javascript" type="text/javascript">
var directionsDisplay;
var directionsService = new
google.maps.DirectionsService();
