WPF - Adding markers to Operational Layers using data from database rather than service

Kaju

I want to create markers on my map from a list containing C# objects with latitude and longitude properties, something similar to the following:

 

class Marker
{
  public int Long { get; set; }
  public int Lat { get; set; }
}

List<Marker> markers = databaseConnection.GetAllMarkers();

// Create Layer from markers
var layer = GetMarkerLayer(markers);

MapView.Map.OperationalLayers.Add(layer);

 

These markers need to be in a feature inside the "operationalLayers" list as I want to do clustering with them.

From my research, it seems like this is only possible by getting the data from a URL or some kind of service, but I want this functionality to be completely offline and mutable.

Is this possible?

The simplest way to do this is to add Graphics to a Graphics Overlay.

See this sample: https://developers.arcgis.com/net/wpf/sample-code/add-graphics-with-renderer/

Look at the MakePointGraphicsOverlay() method.

A Graphic combines a geometry (in this case point) and optionally attributes, and can provide a symbol to determine what it will look like on the map (although you can optionally define a renderer on the Graphics Overlay to provide the symbol, which is what this sample does).
