Introduction

The directionsDisplay in Google Maps helps us to show routes between places.

Description

The Autocomplete widget provides a type-ahead search box . It is operated by using Google Api Key.
The source and destination textbox will show you places.

After putting source and destination then click on button then you will get the realtime duration and distance details with map view.

Steps to be followed

Step1

As I described earlier,

Create a controller action method named "DistanceCalculation" in "HomeController.cs".

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace SatyaGoogleMapBootstrapMVC.Controllers
{
public class HomeController : Controller
{
//
// GET: /Home/
public ActionResult Index()
{
return View();
}
public ActionResult Details()
{
return View();
}
public ActionResult Animate()
{
return View();
}
public ActionResult Icon()
{
return View();
}
public ActionResult Steet()
{
return View();
}
public ActionResult ModeTravel()
{
return View();
}
public ActionResult Traffic()
{
return View();
}
public ActionResult RouteColor()
{
return View();
}
public ActionResult DistanceCalculation()
{
return View();
}
}
}

Then create a view named "DistanceCalculation.cshtml".

@{
ViewBag.Title = "Satyaprakash Goolge Map Distance Calculation";
}
<title>@ViewBag.Title</title>
