How to add a field for mappoints?..

[JenniferNery]

Do you mean how to add attributes to a graphic that has MapPoint geometry?

Graphic g = new Graphic() { Geometry = new MapPoint(x, y, MyMap.SpatialReference) };
g.Attributes["CurrentDate"] = DateTime.UtcNow;
g.Attributes["Greeting"] = "Hello, world!";
g.Attributes["Distance"] = 123.45;
