Declares properties of business objects that can be displayed on a map using the Maps Module.

Namespace: DevExpress.Persistent.Base

Assembly: DevExpress.Persistent.Base.v19.1.dll

Declaration

C#

public interface IMapsMarker :
    IBaseMapsMarker

VB.NET

Public Interface IMapsMarker
    Inherits IBaseMapsMarker

Remarks

You can implement this interface in an XPO or Entity Framework business object. As a result, the WebMapsListEditor or MobileMapsListEditor will be used to display List Views of this business object. Each object is displayed as a marker. The Marker title is displayed after clicking a marker. An object’s Detail View is displayed after clicking the Show details link below the title.

public class Location : BaseObject, IMapsMarker {
    public Location(Session session) : base(session) { }
    //...
    private string title;
    public string Title {
        get { return title; }
        set { SetPropertyValue("Title", ref title, value); }
    }
    private double latitude;
    public double Latitude {
        get { return latitude; }
        set { SetPropertyValue("Latitude", ref latitude, value); }
    }
    private double longitude;
    public double Longitude {
