EndSaveEdits ... Graphics collection is empty after successfully adding!

michaelrosen

I'm need to add rows that contain a FK into a primary table (wrapped by an ArcGISLocalFeatureLayer).  When I add the row into the primary table, everything indicates success in the EndSaveEdits ... but sometimes the the Graphics collection still shows empty.  Can someone offer some suggestions or insight?

            theFeatureLayer.EndSaveEdits += (s2, endEditEventArgs) =>
            {
              
                // I observe that after adding a row, sometimes  endEditEventArgs.Results.AddResults is 1 but theFeatureLayer.Graphics.Count is 0.  Why is that and what can I do about it?

                System.Diagnostics.Debug.Assert(theFeatureLayer == s2); // ok, as expected.

                if (endEditEventArgs.Results.AddResults != null)
                {
                    foreach (EditResultItem r in endEditEventArgs.Results.AddResults)
                    {
                        if (!r.Success)
                        { // no problem here...
                            theLogger.WriteLine(String.Format("EndSaveEdits skipped item due to '{0}'", r.ErrorDescription));
                            continue;
                        }
                        // Fails b/c the Graphics collection is empty.
                        Graphic gr = theFeatureLayer.Graphics.Single(g => (int)g.Attributes["OBJECTID"] == (int)r.ObjectID);
                        if (gr != null)
                        { // need to use the Graphic we just added.  If only it were available....

You have to be aware of the layer's lifecycle:

first the layer must be created.....

Code:
var myLayer = new ArcGISLocalFeatureLayer(); // all code required to create it then initialize it

Code:
myLayer.Initialize(); ....and wait
When it finish to initialize (myLayer.Initialized event).....
you must update it

Code:
myLayer.Update(); .....and wait again...
When it finish to update (myLayer.UpdateCompleted event)....Voila!!!! you have your Graphics!!!
