Note

Bing Maps Web Control SDK retirement

Bing Maps Web Control SDK is deprecated and will be retired. Free (Basic) account customers can continue to use Bing Maps Web Control SDK until June 30th, 2025. Enterprise account customers can continue to use Bing Maps Web Control SDK until June 30th, 2028. To avoid service disruptions, all implementations using Bing Maps Web Control SDK will need to be updated to use Azure Maps Web SDK by the retirement date that applies to your Bing Maps for Enterprise account type. For detailed migration guidance, see Migrate Bing Maps Enterprise applications to Azure Maps with GitHub Copilot.

Azure Maps is Microsoft's next-generation maps and geospatial services for developers. Azure Maps has many of the same features as Bing Maps for Enterprise, and more. To get started with Azure Maps, create a free Azure subscription and an Azure Maps account. For more information about azure Maps, see Azure Maps Documentation. For migration guidance, see Bing Maps Migration Overview.

This example shows how to get all the shapes that are in the drawing manager at any time.

	<script type='text/javascript'>
    var map, drawingManager;

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

        Microsoft.Maps.loadModule('Microsoft.Maps.DrawingTools', function () {
            var tools = new Microsoft.Maps.DrawingTools(map);

            tools.showDrawingManager(function (manager) {
                drawingManager = manager;
            })
        });
    }

    function getShapes() {
        var shapes = drawingManager.getPrimitives();

        if (shapes && shapes.length > 0) {
            alert('Retrieved ' + shapes.length + ' from the drawing manager.');
        } else {
            alert('No shapes in the drawing manager.');
        }
    }
    </script>

<body>
    <div id="myMap" style="position:relative;width:600px;height:400px;"></div><br/>
    <input type="button" value="Get Shapes" onclick="getShapes()"/>
</body>
</html>

Tip

If you want to get a shape right after it was drawn, use the drawingEnded event on the DrawingManager.
