Bind Map to View Model

MVC enables you to natively bind parts of the page to the Model that is passed from the controller.

Using this technique, you can also bind Telerik UI Map HtmlHelper for ASP.NET MVC methods to the Model and populate the Markers collection to a collection that is defined in the Model.

The following example demonstrates how to set up the models.

public class Map
{
    // The Map properties.
    public string Name { get; set; }
    public double CenterLatitude { get; set; }
    public double CenterLongitude { get; set; }
    public int Zoom { get; set; }

    // The tile layer properties.
    public string TileUrlTemplate { get; set; }
    public string[] TileSubdomains { get; set; }
    public string TileAttribution { get; set; }

    // The markers collection.
    public IEnumerable<Marker> Markers { get; set; }
}
public class Marker
{
    public Marker(double latitude, double longitude, string sname)
    {
        latlng = new double[] { latitude, longitude };
        name = sname;
    }

    public double[] latlng { get; set; }
    public string name { get; set; }
}

The following example demonstrates how to set up the Controller.

public ActionResult Index()
{
    var map = new TelerikMvcApp.Models.Map()
    {
        Name = "MyMap",
        CenterLatitude = 30.268107,
        CenterLongitude = -97.744821,
        Zoom = 3,
        TileUrlTemplate = "http://#= subdomain #.tile.openstreetmap.org/#= zoom #/#= x #/#= y #.png",
        TileSubdomains = new string[] { "a", "b", "c" },
        TileAttribution = "&copy; <a href='http://osm.org/copyright'>OpenStreetMap contributors</a>",
        Markers = new List<Marker>
        {
            new Marker(30.268107, -97.744821, "Austin, TX")
        }
    };

    return View(map);
}

The following example demonstrates how to set up the View.

@model TelerikMvcApp.Models.Map

@(Html.Kendo().Map()
        .Name(Model.Name)
        .Center(Model.CenterLatitude, Model.CenterLongitude)
        .Zoom(Model.Zoom)
        .Layers(layers => layers
            .Add()
            .Type(MapLayerType.Tile)
            .UrlTemplate(Model.TileUrlTemplate)
            .Subdomains(Model.TileSubdomains)
            .Attribution(Model.TileAttribution)
        )
        .Markers(markers =>
        {
            foreach (var marker in Model.Markers)
            {
                markers.Add()
                .Location(marker.latlng)
                .Title(marker.name);
            }
        })
)
