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.

I have only seen this once. It's possible this is because I am using multiple maps at the same time. I think it crashed the application, but I do not recall.

The issue is reproduced mainly, when animated items are brought out of the viewport and then reenter the viewport.

In reference to: https://www.telerik.com/forums/binding-question

This sample project is not exactly the same as my actual project, but has the same issue.

I have multiple maps visible. I have a PolygonData that I want to be visible on both maps. It shows up fine. However, the polygon on the first map will not scale when zooming with the FIRST map. If I zoom with the SECOND map, both polygons will correctly scale.

If I replace PolygonData with my own object (PolygonVM), both polygons always correctly scale.

OpenStreetMap provider uses OpenStreetMapSources which have MaxZoomLevel 18.

When Wraparound of the Map is True and you move (with SetView or ZoomLevel + Center properties) the map to zoomlevel > 18 , no tiles are loaded.

RadMap with Wraparound = True. Custom TiledProvider with custom TileSource is used.

GetCachedTile is overridden to get the cached tiles in the local file system.

When zooming , endless invocation of GetCachedTile method is performed which leads to increasing of CPU usage.

BingRestMapProvider always search with Structured URL and that is why it fails to find locations via long query search strings like: 

"royalton rd & brecksville rd brecksville oh"

You can see the difference between Structured and Unstructured rest search URLs here:

https://msdn.microsoft.com/en-us/library/ff701711.aspx



As a workaround, users can override BingRestMapProvider like so:

 public class CustomBingRestProvider : BingRestMapProvider
    {    
        protected override Uri BuildSearchLocationRequestUri(BingRestSearchLocationRequest request)
        {
            Uri baseUri = base.BuildSearchLocationRequestUri(request);

            string newPath = baseUri.AbsoluteUri.Replace("Locations/", "Locations/?q=");

            return new Uri(newPath); ;
        }

MiniMapWidth and MiniMapHeight have default values 250 and 200. If you use different values, for example 250 and 250, panning the RadMap can result in jumping the minimap - unexpected zoom in/out. This is easier to observe with MiniMap, outside RadMap. 

Playing with Width / Height of the MiniMap might workaround the issue.

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.

By design, a UserData property must be presented in the arguments of the  SearchLocationCompleted, CalculateElevationCompleted and CalculateRouteCompleted events of the BingRestMapProvider.  It should provide the UserData object given to the corresponding request classes.

When you have a bindable wrapper as MapEllipseView, MapPolygonView, etc. and bind its ShapeFill property to the view model, the fill is not applied.

This is resolved when the UseRegularFill() method of the MapDataShape object is called manually. You can use this approach to work around the issue.

Width / Height of the MapEllipseView are bound to doubles from ViewModel.

Runtime change to 0 does not hide / remove the Ellipse from the Map.

This is a bug in the MapShapeBindableWrapper's Geometry update code. 

The workaround is to use the Visibility of the MapEllipseView in order to hide it.

Other workaround could be using FrameworkElements (Ellipse, Polyline, Rectangle) instead of BindableWrappers (MapEllipseView, MapPolylinerView, MapRectangleView).

When CommandBarVisibility is Collapsed in VS2013 and Office2013 themes, the zoombar and navigation bar are misplaced.


As a workaround users might set  CommandBarVisibility="Hidden".

When WrapAround is set to TRUE, the MapItemsRequest does not fire when you pan endlessly in one direction.

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().

The Opacity of the provider is not respected by any new map sources added at runtime

To work this around you can set the Opacity of the source manually.

provider.MapSources.Add(new CustomTiledSource() { Opacity = 0.5 });

When you have two providers - BingMapProvider and custom TiledProvider - and the map source of the second provider (the custom one) is changed, the updated provider is drawn under the provider defined before it in the Providers collection (the BingMapProvider).

To work this around you can call the BingMapProvider's SetMapSource() method after the source of the custom provider is changed.

// set the custom provider source
bingMapProvider.SetMapSource(bingMapProvider.SupportedSources[0]);
