To add a mini map to a map, do the following.
- Create a MiniMap object.
- Specify the parameters of the mini map.
- Assign it to the
MapControl.MiniMap
property.
// In the Form's constructor.
object data = LoadData(@"..\..\Data\Ships.xml");
// Create a mini map and data for it.
MiniMap miniMap = new MiniMap();
miniMap.Alignment = MiniMapAlignment.BottomLeft;
miniMap.Layers.AddRange(new MiniMapLayerBase[] {
new MiniMapImageTilesLayer() {
DataProvider = new BingMapDataProvider() {
BingKey = "YOUR_BING_MAPS_KEY_HERE"
}
},
new MiniMapVectorItemsLayer() {
Data = CreateMiniMapAdapter(data)
}
});
map.MiniMap = miniMap;
// Creates an adapter for the map's vector layer.
private IMapDataAdapter CreateAdapter(object source) {
ListSourceDataAdapter adapter = new ListSourceDataAdapter();
adapter.DataSource = source;
adapter.Mappings.Latitude = "Latitude";
adapter.Mappings.Longitude = "Longitude";
adapter.AttributeMappings.Add(new MapItemAttributeMapping() { Member = "Name", Name = "Name" });
adapter.AttributeMappings.Add(new MapItemAttributeMapping() { Member = "Year", Name = "Year" });
adapter.AttributeMappings.Add(new MapItemAttributeMapping() { Member = "Description", Name = "Description" });
return adapter;
}
// Loads data from a XML file.
private List<ShipwreckData> LoadData(string path) {
return XDocument.Load(path).Element("Ships").Elements("Ship")
.Select(e => new ShipwreckData(
year: Convert.ToInt32(e.Element("Year").Value, CultureInfo.InvariantCulture),
name: e.Element("Name").Value,
description: e.Element("Description").Value,
latitude: Convert.ToDouble(e.Element("Latitude").Value, CultureInfo.InvariantCulture),
longitude: Convert.ToDouble(e.Element("Longitude").Value, CultureInfo.InvariantCulture)
))
.ToList();
}
public class ShipwreckData {
public int Year { get; }
public string Name { get; }
public string Description { get; }
public double Latitude { get; }
public double Longitude { get; }
public ShipwreckData(int year, string name, string description, double latitude, double longitude) {
this.Year = year;
this.Name = name;
this.Description = description;
this.Latitude = latitude;
this.Longitude = longitude;
}
