    //Creating the GenericTileProvider instance
    Telerik.Reporting.GenericTileProvider genericTileProvider1 = new Telerik.Reporting.GenericTileProvider();

    //Setting the attribution text that will be shown at the bottom right corner of the map control.
    genericTileProvider1.Attribution = "Tiles courtesy of MapQuest";

    //Setting the URL to the image file that will be used to download the tile provider logo, if required by the provider's usage policy
    genericTileProvider1.LogoUrl = "http://developer.mapquest.com/content/osm/mq_logo.png";

    //Specifying the URL template that will be used to get the tiles from the tile server.
    genericTileProvider1.UrlTemplate = "http://{subdomain}.mqcdn.com/tiles/1.0.0/map/{zoom}/{x}/{y}.jpg";

    //Adding the subdomains used to distribute the tile requests evenly. They will replace the {subdomain} tag in the UrlTemplate.
    genericTileProvider1.UrlSubdomains.Add("otile1");
    genericTileProvider1.UrlSubdomains.Add("otile2");
    genericTileProvider1.UrlSubdomains.Add("otile3");
    genericTileProvider1.UrlSubdomains.Add("otile4");

    //Assigning the tile provider to the map instance
    this.map.TileProvider = genericTileProvider1;
}

Public Sub HowToInitializeGenericTileProvider()
    'Creating the GenericTileProvider instance
    Dim genericTileProvider1 As New Telerik.Reporting.GenericTileProvider()

    'Setting the attribution text that will be shown at the bottom right corner of the map control.
    genericTileProvider1.Attribution = "Tiles courtesy of MapQuest"

    'Setting the URL to the image file that will be used to download the tile provider logo, if required by the provider's usage policy
    genericTileProvider1.LogoUrl = "http://developer.mapquest.com/content/osm/mq_logo.png"

    'Specifying the URL template that will be used to get the tiles from the tile server.
    genericTileProvider1.UrlTemplate = "http://{subdomain}.mqcdn.com/tiles/1.0.0/map/{zoom}/{x}/{y}.jpg"

    'Adding the subdomains used to distribute the tile requests evenly. They will replace the {subdomain} tag in the UrlTemplate.
    genericTileProvider1.UrlSubdomains.Add("otile1")
    genericTileProvider1.UrlSubdomains.Add("otile2")
    genericTileProvider1.UrlSubdomains.Add("otile3")
    genericTileProvider1.UrlSubdomains.Add("otile4")
