Layer.UpdateFeatures(); Layer.SaveFeatureChanges() is Slow

324 Views, 2 Replies

I am working with the AutoDesk Geospatial platform API to connect to a SQL2008 spatial database. I have my application working but whenever I try to add/update features and save the changes it takes a long time. It takes about 5 seconds which making a user wait five seconds to add a feature is too long.

Is this the right approch to add features or is there another method to update features and then save to the database?


Here is a section of my code:


MgFeatureCommandCollection commands = new MgFeatureCommandCollection();

commands.Add(new MgInsertFeatures(MyPointLayer.FeatureClassName, propcol));




Any insight would be appricated.

I think you don't have to call SaveChanges method on layer and did you try updating features like this


AcMapFeatureService fs = AcMapServiceFactory.GetService(MgServiceType.FeatureService) as AcMapFeatureService;

fs.UpdateFeatures(new MgResourceIdentifier(layer.FeatureSourceId), commands, false);

I found a documentation site that explains this.


I tried the featureservice method but the problem is AutoCAD does not update the layer correctly. It saves the data to the datasource but then AutoCAD re-overwrites it and I end up losing data. 


After my command to updateFeatures I would have to refresh each layer which takes longer then the "Edit Set" method from the above link.
