Sorry, when I looked at that later I see it would not work but we don't want to be using ItemsSource with the FeatureDataGrid, that is there because it inherits from DataGrid but really should be working with the GraphicsLayer property as the binding property. You said you had it working to load the entire FeatureLayer data using code the Jenifer provided.  If you go back to that setup than the only part missing is filtering the list after the relationship query.  In that setup you have a class level variable l which is the FeatiureLayer.  I am going to call that _featureLayer because I hate having a variable named l. Right now you have         private void QueryTask_ExecuteRelationshipQueryCompleted(object sender, RelationshipEventArgs e)         {               IEnumerable<Graphic> graphics = e.Result.RelatedRecordsGroup.First().Value;                RelationshipResult pr = e.Result;              if (pr.RelatedRecordsGroup.Count == 0)              {                    RelatedRowsDataGrid.ItemsSource = null;              }              else              {                  foreach (var pair in pr.RelatedRecordsGroup)                  {                        RelatedRowsDataGrid.ItemsSource = pair.Value;                      MyFDG.ItemsSource = pair.Value;                                          }              }         } What needs to happen in the RelationshipComplete handler is that the FeatureLayer (_featureLayer) gets filtered to only show the correct records.         private void QueryTask_ExecuteRelationshipQueryCompleted(object sender, RelationshipEventArgs e)         {             //This line gets you the all features returned from the Relationship Query             IEnumerable<Graphic> graphics = e.Result.RelatedRecordsGroup.First().Value;                          // There are two ways to filter either using Where clause or using the ObjectIDs property             // before you set the Where clause to return all records 1=1 I think             // Here instead lets use the ObjectIDs approach, first get rid of the old Where                    _featureLayer.Where = null //remember _featureLayer is l                                      //ObjectIDs takes an int[] and with a little Linq we can get that array             // I am assumning you have included OBJECTID in your outfields when you defined the query                          int[] objectIds = graphics.Select(g => (int)g.Attributes["OBJECTID"]).ToArray();               //now set the ObjectIDs on our FeatureLayer                          _featureLayer.ObjectIDs = objectIds;               //Update the FeatureLayer to 'redraw' the new filtered set of Features                     _featureLayer.Update();               //And I hope this worked.  you could rebind the layer to the grid to make sure all is good             MyFDG.GraphicsLayer = _featureLayer;           } Hope that helps -Joe ...

So went back to this to see if I could track down the problem.  Set up everything the same as it had been, and it is working update fine Graphics are loaded.  I looked back in subversion and I swear it is the same code that was failing.  I am going to blame it on solar flares or something of that nature.  All I know is it is working so I will just be happy about that and move forward.
