Google Map Using Bootstrap In ASP.NET MVC - Part One


Google Maps API allows you to display maps on your ASP.NET MVC Website.

API means Application Programming Interface.


An API is a set of methods and tools, which can be used for building software Applications.


You will need to register and get an API key from Google API, which will be used to load and display Google Map.
Create a MVC Application named SatyaGoogleMapBootstrapMVC.

Now, create a controller class file named HomeController.cs. 
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Web;  
  5. using System.Web.Mvc;  
  7. namespace SatyaGoogleMapBootstrapMVC.Controllers  
  8. {  
  9.     public class HomeController : Controller  
  10.     {  
  11.         //  
  12.         // GET: /Home/  
  14.         public ActionResult Index()  
  15.         {  
  16.             return View();  
  17.         }  
  18.         public ActionResult Details()  
  19.         {  
  20.             return View();  
  21.         }  
  23.     }  

Create a View based on Controller Action Method Index named Index.cshtml.
  1. @{  
  2.     ViewBag.Title = "Satyaprakash Bhubaneswar Google Map";  
  3. }  
  5. <title>@ViewBag.Title</title>  
  7. <h2 style="background-color: Yellow;color: Blue; text-align: center; font-style: oblique">Satyaprakash's Bhubaneswar Google Map Using MVC and BOOTSTRAP</h2>  
  8. <fieldset>  
  9.     <legend style="font-family: Arial Black; color: blue; font-size: large;">Check Bhubaneswar City</legend>  
  10.     <meta charset="utf-8">  
  11.     <meta name="viewport" content="width=device-width, initial-scale=1">  
  12.     <link rel="stylesheet" href="">  
  13.     <script src=""></script>  
  14.     <script src=""></script>  
  16.     <div id="googleMap" style="height:400px;width:100%;"></div>  
  17.     <script>  
  18.         function myMap() {  
  19.             var myCenter = new google.maps.LatLng(20.296100, 85.824500);  
  20.             var mapProp = { center: myCenter, zoom: 12, scrollwheel: false, draggable: true, mapTypeId: google.maps.MapTypeId.ROADMAP };  
  21.             var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);  
  22.             var marker = new google.maps.Marker({ position: myCenter });  
  23.             marker.setMap(map);  
  24.         }  
  25.     </script>  
  26.     <script src=""></script>  
  27. </fieldset>  
  28. <footer>  
  29.     <p style="background-color: Yellow; font-weight: bold; color:blue; text-align: center; font-style: oblique">© @DateTime.Now.ToLocalTime()</p> @*Add Date Time*@  
  30. </footer> 
Here, I added some script reference file to keep loading of Google map and support mobile View, using Bootstrap.
  1. <link rel="stylesheet" href="">  
  2.     <script src=""></script>  
  3.     <script src=""></script> 
In div tag, I set the Google map view width and height. This also defines the map container and size.
  1. <div id="googleMap" style="height:400px;width:100%;"></div> 
Create a function to set the map properties.
  1. <script>  
  2.         function myMap() {  
  3.             var myCenter = new google.maps.LatLng(20.296100, 85.824500);  
  4.             var mapProp = { center: myCenter, zoom: 12, scrollwheel: false, draggable: true, mapTypeId: google.maps.MapTypeId.ROADMAP };  
  5.             var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);  
  6.             var marker = new google.maps.Marker({ position: myCenter });  
  7.             marker.setMap(map);  
  8.         }  
  9.     </script>  
  1. var mapProp = { center: myCenter, zoom: 12, scrollwheel: false, draggable: true, mapTypeId: google.maps.MapTypeId.ROADMAP }; 
The mapProp variable defines the properties for the map. The center property specifies where to center the map (using latitude and longitude coordinates). The zoom property specifies the zoom level for the map (try to experiment with the zoom level).
  1. var map=new google.maps.Map(document.getElementById("googleMap"), mapProp);  
The given code creates a new map inside the <div> element with an id= googleMap, using the parameters, which are passed (mapProp).
  1. var marker = new google.maps.Marker({ position: myCenter });  
  2. marker.setMap(map); 
The marker variable set the marker position as given latitude and longitude coordinates. Then marker pass the map varible properties in setmap function.
  1. scrollwheel: false, draggable: true  
This is defined in Google map scroll wheel. Proceed, as shown below.
  1. mapTypeId: google.maps.MapTypeId.ROADMAP    
Here, you can set Google map and type I set here as ROADMAP.
Google allows a Website to use any Google API for free, millions of times a day.

Go to

Now, you have to sign in to your Gmail account and you will get the key.

Google Maps expects to find the API key in the key parameter when loading an API.
