Hello
I add some icon to my map with this code:
///////
FeatureSet _markers;
MapPointLayer _markerLayer;
System.Drawing.Image imobj = Image.FromFile(@"..\BallChartreuse.png");
_markers = new FeatureSet(FeatureType.Unspecified) { Projection = map1.Projection };
_markerLayer = new MapPointLayer(_markers);
_markerLayer.Symbolizer = new DotSpatial.Symbology.PointSymbolizer(imobj, 30);
map1.Layers[0].MapFrame.DrawingLayers.Add(_markerLayer);

void map_MouseUp(object sender, MouseEventArgs e)
    {
        if (e.Button != MouseButtons.Right) return;
        Coordinate c = map1.PixelToProj(e.Location);
        _markers.AddFeature(new DotSpatial.Topology.Point(c));
        map1.Layers[0].MapFrame.Invalidate();

    }
/////

it is ok but haw can I save the result.if I save markers,it just save point without Icon.
Please answer me.
Thanks
