Hi @Ethan please Check this code is there anything wrong. When we are using this code whole Graticule layer is coming as small tiles with coordinates.
LineStyle customDashLineStyle = LineStyles.CreateSimpleLineStyle(GeoColor.FromArgb(Convert.ToInt32(GraticuleColor.Split(',')[0]), Convert.ToInt32(GraticuleColor.Split(',')[1]), Convert.ToInt32(GraticuleColor.Split(',')[2]), Convert.ToInt32(GraticuleColor.Split(',')[3])), 1, LineDashStyle.Custom, true);
customDashLineStyle.CenterPen.DashPattern.Add(4f);
customDashLineStyle.CenterPen.DashPattern.Add(4f);
customDashLineStyle.CenterPen.DashPattern.Add(4f);
customDashLineStyle.CenterPen.DashPattern.Add(4f);
GraticuleFeatureLayer graticuleAdornmentLayer = new GraticuleFeatureLayer(_proj);
//graticuleAdornmentLayer.WrappingMode = WrappingMode.WrapDateline;
//graticuleAdornmentLayer.WrappingExtent = _proj.ConvertToExternalProjection(new RectangleShape(-180, 90, 180, -90));
graticuleAdornmentLayer.GraticuleLineStyle = customDashLineStyle;
LayerOverlay graticuleAdornmentLayerOverlay = ((LayerOverlay)wfMap.CustomOverlays["AllOverlays"]);
if (graticuleAdornmentLayerOverlay.Layers.Contains("GraticuleAdornmentLayer"))
graticuleAdornmentLayerOverlay.Layers.Remove("GraticuleAdornmentLayer");
graticuleAdornmentLayerOverlay.Layers.Add("GraticuleAdornmentLayer", graticuleAdornmentLayer);
