    Hi everyone,


    I'm using the OpenStreetMapProvider for a long time now, but since this monday I have a problem. Instead of the real map tiles see the the pictures you can see in the attached file. I don't understand whats wrong here. I'm not using MapQuest. And Openstreetmap is still free to use.


    Can someone tell me how to solve this, so I can have my map back?


    Best Regards

    If you are getting this it means you must be using the Map Quest Open Street Map tile server. That server was shutdown on 7/11/2016.

    Maybe you are using the OpenStreetMapQuestSource class provided by Telerik?

    You will need to switch map providers. You might try MapBox, you will need to have an account and you may need to create a custom map provider and source.

    We created a TitleProovider that allows us to try multiple services by swapping out the TiledMapSource, so when MapQuest shutdown their service, we moved to Mapbox which we had already implemented.

    Here is the bit of our MapBoxSimpleItsSource class that does the work:

    protected override Uri GetTile(int tileLevel, int tilePositionX, int tilePositionY)
        int zoomLevel = ConvertTileToZoomLevel(tileLevel);
        string tileUrl = string.Format(
        return new Uri(tileUrl);

    No, unless Telerik is doing so in the background, I'm actually not using MapQuest.

    I'm using the the Telerik.Windows.Controls.Map.OpenStreetMapProvider. Just like it is explained this article

    same problem for us...I removed  the SetMapSource method from OpenStreetMapProvider


    var ret = new OpenStreetMapProvider();              //ret.SetMapSource("Telerik.Windows.Controls.Map.OpenStreetMapQuestSource");
