Map HtmlHelper Overview
The Telerik UI Map HtmlHelper for ASP.NET MVC is a server-side wrapper for the Kendo UI Map widget.
The Map displays geospatial information organized in layers and is supported for both desktop and mobile devices. It also provides tile layers, shape (vector) layers, and marker layers.
The Map is part of Telerik UI for ASP.NET MVC, a
professional grade UI library with 110+ components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.
Initializing the Map
The following example demonstrates how to define the Map by using the Map HtmlHelper.
@(Html.Kendo().Map()
.Name("map")
.Center(35.268107, -95.744821)
.Zoom(2)
.Layers(layers =>
{
layers.Add()
.Type(MapLayerType.Tile)
.UrlTemplate("http://#= subdomain #.tile.openstreetmap.org/#= zoom #/#= x #/#= y #.png")
.Subdomains("a", "b", "c")
.Attribution("© <a href='http://osm.org/copyright'>OpenStreetMap contributors</a>");
})
.Markers(markers =>
{
markers.Add()
.Location(30.268107, -97.744821)
.Shape(MapMarkersShape.PinTarget)
.Tooltip(tooltip => tooltip.Content("Austin, TX"));
})
)
public partial class MapController : BaseController
{
[Demo]
public IActionResult Index()
{
return View();
}
}
Basic Configuration
The following example demonstrates the basic configuration for the Map HtmlHelper.
<input id="zoomLevel"/>
<button id="zoom" class="k-button">zoom()</button>
@(Html.Kendo().Map()
.Name("map")
.Center(30.268107, -97.744821)
.Zoom(3)
.Layers(layers =>
{
layers.Add()
.Type(MapLayerType.Tile)
.UrlTemplate("http://tile2.opencyclemap.org/transport/#= zoom #/#= x #/#= y #.png")
.Subdomains("a", "b", "c")
.Attribution("© <a href='http://osm.org/copyright'>OpenStreetMap contributors</a>." +
"Tiles courtesy of <a href='http://www.opencyclemap.org/'>Andy Allan</a>");
})
)
<script>
$("#zoom").click(function (e) {
var map = $("#map").data("kendoMap")
map.zoom(
parseInt($("#zoomLevel").val(), 10)
);
});
</script>
Events
For a complete example on basic Map events, refer to the demo on using the events of the Map.
@(Html.Kendo().Map()
.Name("map")
.Layers(layers =>
{
layers.Add()
.Type(MapLayerType.Tile)
.UrlTemplate("http://#= subdomain #.tile.openstreetmap.org/#= zoom #/#= x #/#= y #.png")
.Subdomains("a", "b", "c");
})
.Events(e => e
.Reset("mapReset")
)
)
<script>
function mapReset(e) {
// Handle the reset event.
}
</script>
