    Is it possible to draw shapes on the map with a mouse?  I do not see mouse events exposed for the map or shape layer.

    Here is some code I have been trying,



    var _drawing = false;
    var _currentShape = null;
    var _shapeData = new Array(0);
    var _map = $("#map").data("kendoMap");
    var _shapeLayer = _map.layers[2];
    var _lineShapeFactory = new LineShapeFactory();
    var _polygonShapeFactory = new PolygonShapeFactory();

    var _counter = 0;

    function mapMouseDown(e) {
        var location = _map.eventToLocation(e);

        _currentShape = new _lineShapeFactory.CreateNew();

        _currentShape.coordinates.push(new Array(location.lat, location.lng));

        _currentShape.coordinates.push(new Array(location.lat, location.lng));


        _shapeLayer.datasource = _shapeData;

        _drawing = true;


        var foo = null;

    function mapMouseMove(e) {

        if (_drawing == false) {

        var location = _map.eventToLocation(e);

        if (_currentShape.type == "Linestring") {
            _currentShape.coordinates[1] = new Array(location.lat, location.lng);

        var test = _shapeData;


        if (counter == 100) {
            var foo = null;


    function mapMouseUp(e) {
        _drawing = false;


    function LineShapeFactory() {
        this.CreateNew = function () {
            var newLineString = {
                "type": "Linestring",
                "coordinates": new Array(0)

            return newLineString;

    The map is named "map", and it has in this order a tile layer, a marker layer, and a shape layer.

    Using the shape layer as a drawing surface is an interesting idea. It makes possible to persist the changes in a standard format. We'll consider it as a full-blown feature.

    Please, file a request for this feature on our UserVoice portal if you have minute.
    This will help us gauge the overall interest and prioritize.

    Did the ability to draw get accepted into the Map component?

    Hello Matt,


    I am afraid that such functionality is not available out of the box. Furthermore, there is no request for it in our feedback portal.



    If you would like to request the feature please log an item in the portal. We prioritize the requests based on the customer demand and the impact they would have for a given component.
