DrawingManager Events

The example adds a bunch of events to the drawing manager that is created by the drawing tools module. As the different events first a label will be highlighted in green to indicate which event(s) have fired.

    var map, drawingManager;

    function GetMap() {
        map = new Microsoft.Maps.Map('#myMap', {});

        //Load the DrawingTools module
        Microsoft.Maps.loadModule('Microsoft.Maps.DrawingTools', function () {
            //Create an instance of the DrawingTools class and bind it to the map.
            var tools = new Microsoft.Maps.DrawingTools(map);

            //Show the drawing toolbar and enable editting on the map.
            tools.showDrawingManager(function (manager) {

                //Add events to the drawing manager.
                Microsoft.Maps.Events.addHandler(manager, 'drawingChanged', function () { highlight('drawingChanged'); });
                Microsoft.Maps.Events.addHandler(manager, 'drawingChanging', function () { highlight('drawingChanging'); });
                Microsoft.Maps.Events.addHandler(manager, 'drawingEnded', function () { highlight('drawingEnded'); });
                Microsoft.Maps.Events.addHandler(manager, 'drawingErased', function () { highlight('drawingErased'); });
                Microsoft.Maps.Events.addHandler(manager, 'drawingModeChanged', function () { highlight('drawingModeChanged'); });
                Microsoft.Maps.Events.addHandler(manager, 'drawingStarted', function () { highlight('drawingStarted'); });

    function highlight(id) {
        //Highlight the mouse event div to indicate that the event has fired.
        document.getElementById(id).style.background = 'LightGreen';

        //Remove the highlighting after a second.
        setTimeout(function () { document.getElementById(id).style.background = 'white'; }, 1000);
    <script type='text/javascript' src='http://www.bing.com/api/maps/mapcontrol?callback=GetMap&key=[YOUR_BING_MAPS_KEY]' async defer></script>
    <div id="myMap" style="position:relative;width:600px;height:400px;"></div>

    <div id="drawingChanged">drawingChanged</div>
    <div id="drawingChanging">drawingChanging</div>
    <div id="drawingEnded">drawingEnded</div>
    <div id="drawingErased">drawingErased</div>
    <div id="drawingModeChanged">drawingModeChanged</div>
    <div id="drawingStarted">drawingStarted</div>

Running this code in a browser you will see the different events highlighted in green as you draw a shape on the map.
