Map for WinForms - Connect to the OpenStreetMap Service

This example uses OpenStreetMapDataProvider to connect Map Control to the OpenStreetMap service.

IMPORTANT: Specify a valid OSM server name in the OpenStreetMapDataProvider.TileUriTemplate property. For instance, you can set your own tile server, use a public OSM server or choose alternative OSM servers. For more information, refer to the following article: Tile Usage Policy.

Follow the steps below to display the OpenStreetMap geodata in the Map Control:

• Use the ServicePointManager.SecurityProtocol property to specify the network security protocol before the InitializeComponent method call.

• Create a MapControl object. Set the MapControl.Dock property to the DockStyle.Fill value to fit the Map Control to the form. Call the Add method to add the Map Control to the form's control collection.

• Create ImageLayer and use the MapControl.Layers.Add method to add this layer to the map.

• Create an OpenStreetMapDataProvider object and assign it to the ImageLayer.DataProvider property. Specify the OpenStreetMapDataProvider.TileUriTemplate property to load data from an OSM server. Our example contains a sample template string that does not connect to an existing OSM server.

• Handle the OpenStreetMapDataProvider.WebRequest event and specify the e.UserAgent and e.Referer properties in the event handler.
