Is there a way to get the map to continuously scroll without seeing the gray area? As an example, GoogleMaps, MapQuest, etc.. let you scroll left to right without getting to the "end of the world", it just continues to wrap around. I'm trying to avoid seeing the gray when I scroll too far left or right.

The feature for WPF will be available with R3 2016 in September.

Export RadMap to screenshot.

WPF: We will add ExportToImage public method for WPF in R1 2017 with option whether to include map objects from Information/VisualizationLayer.

SL: There is a Silverlight limitation in WriteableBitmap:

One partial solution if you use Bing Maps in RadMap is to use the Bing REST Static Map Imagery in order to download Image replicating the current viewport and zoomlevel of the RadMap.

     Bing REST Static Map => 

     Using Bing REST API with .NET =>

Currently only Mercator projection is supported. We should add support for other projections. Shape file reader should be able process .prj file and setup correspondent projection to the EmptyProvider. The Bing and OpenStreet map providers show map using Mercator projection, so they can't use any other projections to show map shapes (KML or ESRI).

Currently RadMaps Geocode, Search and Route providers are based on SOAP.

The Bing Maps discontinue their SOAP services in June 2017. 

The Bing REST Services API  ( includes:

- Imagery API 

    -- Imagery metadata (used for downloading image tiles - already implemented in BingRestMapProvider)

- Routes API 

- Location API

- Elevations API

For R1 2016 we will implement:

Routes API which will be replacement of SOAP based BingRouteProvider

Locations API which will be replacement of SOAP based BingGeocodeProvider

Elevations API which will be new API and has no existing SOAP replacement

Release R3 2019 SP1

If XML of the KML file is not ordered properly (beautified with tabs and new lines), the AsyncKmlReader doesn't read all shapes.

To work this around, beautify the KML file before passing it to the shape reader.

Add the CanvasDark, CanvasLight, CanvasGray, RoadOnDemand and AerialOnDemand modes in the BingRestMapProvider.

Currently it supports only Aerial, Road and BirdsEye and their variants with labels.

Check the imagerySet parameter here:

Ordnance Survey will not be added among with these modes.

Release R2 2019
There is a change in the Open Street Map Cycle and CylcleTransport services and they require an API key. Without it the service will returned tiles with a watermark saying "API KEY REQUIRED". Currently, the OpenStreetProvider doesn't expose a mechanism for providing a key. 

At this point you can provide a key by creating a custom map provider deriving from OpenStreeMapProvider and also a custom OsmTileMapSource. And override the original URL to use also an API Key.

public class CustomOpenStreetMapProvider : OpenStreetMapProvider
    public CustomOpenStreetMapProvider()
        string sourceKey = (typeof(OpenStreetCycleTransportSource)).FullName;
        this.MapSources[sourceKey] = new CustomOpenStreetCycleTransportSource("your api key here");           
public class CustomOpenStreetCycleTransportSource : OsmTileMapSource
    private static string UrlFormat = @"http://{prefix}{zoom}/{x}/{y}.png?apikey={apikey}";
    private string apiKey;
    public CustomOpenStreetCycleTransportSource(string apiKey)
        : base(UrlFormat)
        this.apiKey = apiKey;
    protected override Uri GetTile(int tileLevel, int tilePositionX, int tilePositionY)
        Uri originalUri = base.GetTile(tileLevel, tilePositionX, tilePositionY);
        string newUri = originalUri.OriginalString.Replace("{apikey}", this.apiKey);
        return new Uri(newUri);

Map with VisualizationLayer (VL) bound to collection of objects.

VL uses an ItemTemplate consisting of MapEllipseView object whose Location Width and Height properties are bound to ViewModel's properties.

On a button click, the ItemsSource of the VL is refreshed. However, the ellipses do not appear until a zoom action is performed.

The Location.Parse() method throws FormatException when the source string is saved (using the Location's object ToString() method) and the culture of the application is set to de-DE. 

Note:  The issue can appear with different cultures that use ',' as number decimal separator.

To work this around you can save or parse the Location manually instead of using ToString() and Parse().

MapPath with RotateTransform is added in InformationLayer runtime. Map produces NullReferenceException.

As a workaround you can use Visualizationlayer and PathData.

An exception is thrown in the following scenario:
-We have a data bound VisualizationLayer with MapShapeBindableWrapper elements in its ItemTemplate.
-The view models in the ItemsSource of the layer implements the INotifyLocationChanged interface and its LocationChanged event is manually raised when the Location property is changed
-If the layer's ItemsSource collection is reset and then the Location property the elements of the old collection is changed, an exception is thrown.

The fix will be available in our official release Q1 2016 SP.

RadMap's VisualizationLayer with ClusterGenerator. The default value of AutoExpandWhenSingle is used - TRUE. When removing items from the cluster at runtime, it does not auto expand when only one item is contained in the cluster.

The fix will be available in the internal build from 9.November 2015 as well as in the Q1 2016 official Release.
