Weird Issue with onDeleteFeature event

[BrianBulla]

Hi,

So I've written an Editor Extension which has some code that runs when a feature is deleted.  Everything works 100% as needed, but today I decided to add a few lines of code to track some information in a Share Point List when a feature gets deleted.  As soon as I add that code, none of the code within my onDeleteFeature event fires.  It's like it doesn't even exists.  But....as soon as I comment out the code I added, everything works fine.  Really weird.  I don't know what the heck is going on.

See below.  The code below works, but as soon as I uncomment the commented out section, nothing works.  i don't even get the message box to pop up.  If I debug, nothing in this entire code block runs, but the delete still happens in ArcMap.

Any ideas??

        //When a feature is Deleted.
        void Events_OnDeleteFeature(ESRI.ArcGIS.Geodatabase.IObject obj)
        {
            try
            {
                if (obj is IFeature)
                {
                    //Cast to an IFeature
                    IFeature inFeature = (IFeature)obj;                 
                    ITable inTable = obj.Table;

                    if (inTable is IVersionedObject)
                    {
                        IVersionedObject3 vObject = (IVersionedObject3)inTable;

                        //Check if the Features Table is Versioned.  If not, then exit.
                        if (vObject.IsRegisteredAsVersioned)
                        {
                            //Look for the Maximo field and edit.
                            if (inFeature.Fields.FindField("MXCREATIONSTATE") != -1)
                            {
                                MessageBox.Show("DELETE");
                                //using (SPSite spSite = new SPSite("https://...."))
                                //{
                                //    using (SPWeb spWeb = spSite.OpenWeb())
                                //    {
                                //        spWeb.AllowUnsafeUpdates = true;
                                //        SPList list = spWeb.Lists["GIS_Deletes"];

                                //        //Add an item
                                //        SPListItem newItem = list.Items.Add();
                                //        newItem["MXASSETNUM"] = inFeature.Fields.FindField("MXASSETNUM").ToString();
                                //        newItem["MXSITEID"] = inFeature.Fields.FindField("MXSITEID").ToString();
                                //        newItem.Update();

                                //        spWeb.AllowUnsafeUpdates = false;
                                //    }
                                //}
                            }                                                            
                        }                        
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString(), "Error in OnDeleteFeature procedure.");
            }
            
        }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I know nothing about share point but just for a sanity check could you put say a write to a simple text file in place of that code, so you know that code is executing in that block? If that works suspicion falls upon you SPSite and SPWeb objects.

Hi Duncan,

It took a while but I eventually figured out that I was just using the wrong NuGet package in VisualStudio.  Removing references and then using a different reference to the 2016 Microsoft SharePoint references seemed to fix the issue.

Thanks,
