Obtaining INetworkSource from Edge EID - ArcObjects C#

Muhammad_TayyabMir

I have  a Geometric Network of electric dataset and I'm working on a downstream trace addin using Forward Star.

While tracing, I need to obtain an extra attribute ("Feeder ID") from the source of my geometric network, which is not present in the network attributes.

So far, I have the EID of the Edge, and its geometry, during the trace iteration.

fStar.QueryAdjacentEdges(ref adjEdgeEIDS, ref adjRevOrientations, ref adjEdgeWeights);

for (int i = 0; i < adjEdgeCount; i++)
      {

         int connectedEdgeEID = adjEdgeEIDS;

         IGeometry edgeGeom =(IGeometry) _geomNet.get_GeometryForEdgeEID(connectedEdgeEID);

         // Get source of Edge EID to get FeederID Attribute

      }

Now, I have researched a little and found out that this will be achieved through INetworkSource.
I can obtain SourceID and SourceOID from the INetworkElement of that edge.

What I am unable to figure out is that how to obtain the corresponding NetworkElement from the EID or Goemetry of the Edge I have.

I hope I am going in the right direction. Any help would be appreciated.
Note: I do not have the Network Analyst Extension. I need to do it without needing the Network analyst extension.

Thanks alot Joe! this is exactly what I needed.
About using ArcFM, that really was my first approach. I spent 2 weeks understanding the documentation and doing it through Downstream Trace but I got stuck very bad. I asked a couple on questions on GIS Stack Exchange which no one answered and I did not have a Schneider account to post on their forum. After two weeks I gave up and did it with Forward Star, since my deadline was reaching. 
Will surely go back to that method once I complete it for now.
