        I am trying to use Telerik RadMap (OpenStreet Map) in offline mode(i.e without internet acess).For this purpose I am using Easy Openstreet Map downloader.So

        I have some below queries.

       1) Can we get whole world map as image tiles upto street level zooming by this downloader and integrate the same with radmap or there is some better approach to use offline map(upto street level zooming is a must) ?

       2) How can we search a location by name on radmap (offline mode)[on open street map provider] ?

      3) How to add a place i.e if we want to name a place not marked or already marked on radmap(openstreet map) and it will be permanently stored on the map tiles?

     I am waiting for the reply of above post.As we are planning to purchase telerik UI so we will have to know if these points get satisfied or not.
    Any help will be highly appreciated.

    Hello P Kumar,

    1) The Easy OSM DownLoader can be used freely for downloading tiles up to zoom level 12. For bigger levels you will need to purchase. Once you download the tiles on your machines, you can use the approach given to our clients in some forum threads.
    Offline TiledMapProvider
    Offline Map Server

    2) Currently we do not provide Search Provider for OpenStreet, we only have such one for BingMaps.
    You can create such service class outside the RadMap and use the results from a given search to display objects on RadMap. Actually, as far as I can tell , the search services are provided by some other companies (not directly opensteet). For example MapQuest, Nominatim.

    3) You can use MapMouseClick event, get the mouse geographich location on the map an use it to add objects. You can save these objects location / info in file / db/ dictionary and introduce method that adds the objects on load or on other event ( this is how I understand "permanently stored" - to be visible on every new application load). Let us know if you need different behavior.
