Add different types of markers

Different marker objects can be added to the Maps component using the marker settings. To update different marker settings in Maps, follow the given steps.

Step 1:

To customize the shape of the marker using the Shape property and change the border color and width of the marker using the Border property as mentioned in the following example.

@{
    var data = new[]
    {
        new { latitude=  40.7424509, longitude = -74.0081468, city = "New York"}
    };
    var border = new Syncfusion.EJ2.Maps.MapsBorder
    {
        Width = 2,
        Color = "#333",
        Opacity = 1
    };
}

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Maps
@Html.EJS().Maps("container").Layers(new List<Syncfusion.EJ2.Maps.MapsLayer>
    {
        new Syncfusion.EJ2.Maps.MapsLayer
            {
                ShapeData = ViewBag.usMap,
                MarkerSettings  = new List<Syncfusion.EJ2.Maps.MapsMarker>
                    {
                        new Syncfusion.EJ2.Maps.MapsMarker
                            {
                                Visible = true,
                                DataSource = data,
                                Width= 2,
                                AnimationDuration= 0,
                                Border = border,
                                Fill = "white",
                                Shape = Syncfusion.EJ2.Maps.MarkerType.Circle
                            }
                    }}}).Render()

Marker1.cs

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using EJ2_Core_Application.Models;
using Newtonsoft.Json;

namespace EJ2_Core_Application.Controllers
{
    public class HomeController : Controller
    {
        public IActionResult Index()
        {
            ViewBag.usmap = GetUSMap();
            ViewBag.usMap = GetMap();
            return View();
        }
        public object GetUSMap()
        {
            string allText = System.IO.File.ReadAllText("./wwwroot/scripts/MapsData/USA.json");
            return JsonConvert.DeserializeObject(allText);
        }
        public object GetMap()
        {
            string allText = System.IO.File.ReadAllText(Server.MapPath("~/App_Data/USA.json"));
            return JsonConvert.DeserializeObject(allText, typeof(object));
        }
    }
}

Step 2:

Customize the above option for n number of markers as mentioned in the following example.

    };
    var data2 = new[]
    {
