Dear Sir,
We want show marker on map canvas according to lat. long.
we are apply this process as given below.
-------------------------------------------------------------------------------
winformsMap1.MapUnit = GeographyUnit.DecimalDegree;
winformsMap1.BackgroundOverlay.BackgroundBrush = new GeoSolidBrush(GeoColor.GeographicColors.ShallowOcean);
ShapeFileFeatureLayer worldLayer = new ShapeFileFeatureLayer(path);
worldLayer.Open();
worldLayer.Name = add_node_name;
worldLayer.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level20;
worldLayer.ZoomLevelSet.ZoomLevel01.DefaultAreaStyle = AreaStyles.Country1;
layerOverlay.Layers.Add("wordlayer", worldLayer);
winformsMap1.Overlays.Add(layerOverlay);
worldLayer.Close();
winformsMap1.Refresh();
public void add_marker(double lat_data, double long_data)
{
Marker marker = new Marker(lat_data,long_data);
marker.Image = Properties.Resources.China;
marker.Width = 20;
marker.Height = 34;
marker.YOffset = -17;
SimpleMarkerOverlay markerOverlay = new SimpleMarkerOverlay();
markerOverlay.Markers.Add(marker);
winformsMap1.Overlays.Add(markerOverlay);
winformsMap1.Refresh();
}
-------------------------------------------------------------------------------
Please give me solution.

Marker Not show on .shp file
Hi Harish,
I think that the “MapControl” property isn't specified on "SimpleMarkerOverlay" instances as following statement:
markerOverlay.MapControl = winformsMap1;
Thanks,
Don
Dear Sir,
We are try already this condition this is not working
as
-------------------
public void add_marker(double lat_data, double long_data)
{
Marker marker = new Marker(lat_data,long_data);
marker.Image = Properties.Resources.China;
marker.Width = 20;
marker.Height = 34;
marker.YOffset = -17;
SimpleMarkerOverlay markerOverlay = new SimpleMarkerOverlay();
markerOverlay.MapControl = winformsMap1;
markerOverlay.Markers.Add(marker);
winformsMap1.Overlays.Add(markerOverlay);
winformsMap1.Refresh();
}

Dear Sir,
I am inserting India Lat. Long. Value but the marker
show outside of the Exact Location So please give me solution.
Some code give below
public void add_marker_layer()
{
try
{
SimpleMarkerOverlay markerOverlay = new SimpleMarkerOverlay();
markerOverlay.MapControl = winformsMap1;
winformsMap1.Overlays.Add("MarkerOverlay",
markerOverlay);
winformsMap1.Refresh();
}
catch (Exception
ex)
{
MessageBox.Show(ex.Message, "Error");
}
}
Marker marker;
public void
add_marker()
{
try
{
SimpleMarkerOverlay markerOverlay = (SimpleMarkerOverlay)winformsMap1.Overlays["MarkerOverlay"];
marker
= new Marker(
74.840478,30.421914);
marker.Image = Properties.Resources.AQUA;
marker.Width = 20;

Hi Harish,
Could you please upload a screen capture about your issue?
It looks your code works well.
Does that because your baselayer is based on different projection? It looks your marker is based on WGS84(4326).

Don
