Drag and Drop Markers

The following example demonstrates how to integrate the Kendo UI Draggable widget with the Map.

You can drag and drop the markers within the visible area of the Map. The location of the marker is updated on dropping.

Example

<div id="map"></div>
<script>
    var markers = [
    {"latlng":[30.2675,-97.7409], "name": "Zevo Toys"},
    {"latlng": [30.2707,-97.7490],"name": "Foo Bars"},
    {"latlng": [30.2705,-97.7409],"name": "Mainway Toys"},
    {"latlng": [30.2686,-97.7494], "name": "Acme Toys"}];

    $("#map").kendoMap({
        center: [30.268107, -97.744821],
        zoom: 15,
        layers: [{
            type: "tile",
            urlTemplate: "http://#= subdomain #.tile.openstreetmap.org/#= zoom #/#= x #/#= y #.png",
            subdomains: ["a", "b", "c"],

            }, {
            type: "marker",
            dataSource: {
                transport: {
                    read: function(e) {
                        // Load mock data
                        e.success(markers);
                    }

                    // Update method omitted for simplicity
                }
            },
            locationField: "latlng",
            titleField: "name"
        }],
        markerActivate: function(e) {
            var marker = e.marker;
            var element = marker.element;
            var width = element.width();
            var height = element.height();
            var map = e.sender;

            element.kendoDraggable({
                // Move marker "hot point" under the cursor
                cursorOffset: { top: -height, left: -width / 2 },

                // Create and style drag hint
                hint: function() {
                    var hint = element.clone().css({
                        width: width,
                        height: height,
                        backgroundImage: element.css("backgroundImage")
                    });

                    element.hide();
                    return hint;
                },

                // Constrain drag area
                container: e.layer.map.element,

                // Update marker location
                dragend: function(e) {
                    e.sender.hint.hide();

                    var loc = map.viewToLocation([e.x.client, e.y.client]);
                    marker.dataItem.set("latlng", [loc.lat, loc.lng]);
                }
            });
        }
    });
</script>
