Hi Kenneth, Hi All,
I would like to create new Line (MgFeatureGeometricType.Curve) Layer , and
create line feature in this new Layer , I worked with follwoing steps:
1.Take Layer Definition for Exsisting Line Layer and SetResource as
following
MgByteReader byteReader = resourceService.GetResourceContent(layerDefResId);
XmlDocument doc = new XmlDocument();
String xmlLayerDef = byteReader.ToString();
doc.LoadXml(xmlLayerDef);
String xmlString = doc.DocumentElement.OuterXml;
MgResourceIdentifier layerDefId = new MgResourceIdentifier("Session:" +
GetParameter(this.args, "SESSION") + "//NewLayer.LayerDefinition");
resourceService.SetResource(layerDefId, new MgByteReader(xmlString,
"text/xml"), null);
2. Insert New Layer
layers.Insert(layers.IndexOf(layer), newLayer);
3.Create Line Geometry
MgLinearRing Line = geometryFactory.CreateLinearRing(coordinateColl);
MgGeometry Geom = geometryFactory.CreatePolygon(Line, null);
4.Write Geometry and Update Featur Service
propertyValues.Add(new MgGeometryProperty("Geometry", byteReader1));
updateCommands.Add(new MgInsertFeatures(className, propertyValues));
MgFeatureService featureService =
(MgFeatureService)this.site.CreateService(MgServiceType.FeatureService);
featureService.UpdateFeatures(layerResId, updateCommands, false);
5. Save map and refresh
after previouse steps No thing appear , No bugs , No Result , Only NewLayer
Created
Can you help me plz to update Exsisting Line Layer ?
Best Regards
Akram
