Hey, Try this one:
MgLayer layer = GetLayerByName(map, "ROADS"); -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of staniz Sent: Tuesday, February 10, 2009 4:01 PM To: [email protected] Subject: Re: [mapguide-users] MapGuide Programming using C#, need help, please Dennis, I am really sorry for making you confused because I mistyped the code. These are the original code that I copied from aspx that i got the first error. //Highlight the query result on the map MgSelection selection = new MgSelection(map); MgLayer layer = map.GetLayers().GetItem("Parcels"); featureReader = featureService.SelectFeatures(parcelId, "Parcels", nameQuery); selection.AddFeatures(layer, featureReader, 0); String selectionXML = selection.ToXml(); I changed the line to ---MgLayerBase layer = map.GetLayers().GetItem("Parcels");--- as your suggestion but the Query result is still empty.
