location range within shapes

[Donna]

Is it possible, once a shape is drawn on the map, to be able to determine any pin points that fall within the shape?

Hi Donna,

The information layer contains the GetElementsInRectangle method. You can use it to get pin points within the geographical bounds of the MapShape. Also you can select the pin points which are inside the shape using the InformationLayer.GetItemsInLocation method.
The sample GetPinPointsInShape method is below.

private Collection<MapPinPoint> GetPinPointsInShape(MapShape shape)

{

    Collection<MapPinPoint> points = new Collection<MapPinPoint>();


    var shapes = this.informationLayer.GetElementsInRectangle(shape.GeographicalBounds);

    foreach (object item in shapes)

    {

        MapPinPoint point = item as MapPinPoint;

        if (point != null && this.IsLocationInShape(shape, MapLayer.GetLocation(point)))

        {

            points.Add(point);

        }

    }


    return points;

}


private bool IsLocationInShape(MapShape shapeToTest, Location location)

{

    bool isInShape = false;


    IEnumerable<object> list = this.informationLayer.GetItemsInLocation(location);

    foreach (object item in list)

    {

        MapShape shape = item as MapShape;

        if (shape != null && shape == shapeToTest)

        {

            isInShape = true;

            break;

        }

    }


    return isInShape;

}

This works for me. Thank you very much!
