In ArcObjects, IFeatureCursor.UpdateFeature method is much faster than IFeature.Store.  I just could not find a similar way of UpdateFeature in ArcGIS Pro.  What is the equivalent of UpdateFeature in Pro? ... View more

Updating data to a feature class will be slow when there are some tables joined to it.  The following is the function we used to update the data.  The performances on a feature class with table joined and without table joined are very different.  We are able to duplicate this issue in 2.3, 2.4 and 2.5.         private async Task<bool> UpdateType(FeatureLayer pFeatLyr, List<long> oidSet, string sType)         {             var op = new EditOperation();             FeatureClass pFeatCls = await CHaLayerSrv.GetFeatureClass(pFeatLyr);             //FeatureClass pFeatCls = ((FeatureLayer)pFeatLyr).GetFeatureClass();             try             {                 op.Callback(async context =>                 {                     StringBuilder sb = new StringBuilder();                     sb.Append("OBJECTID IN(");                     foreach (long objId in oidSet)                     {                         sb.Append(objId.ToString() + ",");                     }                     sb.Remove(sb.Length - 1, 1).Append(")");                        string query = sb.ToString();                     using (RowCursor pFeatCur = await CHaMapSelection.SearchFeatures(pFeatCls, query, "", false))                     {                         while (pFeatCur != null && pFeatCur.MoveNext())                         {                             using (Feature pFeat = (Feature)pFeatCur.Current)                             {                                 context.Invalidate(pFeat);                                 pFeat[GlobalConst.SHAPE_TITLE_TYPE] = sType;                                 pFeat.Store();                                 context.Invalidate(pFeat);                             }                         }                     }                 }, pFeatCls);                   if (!op.Execute())                 {                     Console.WriteLine(op.ErrorMessage);                     return false;                 }                 else                 {                     return true;                 }             }             catch (Exception ex)             {                 Console.WriteLine(ex.Message);                   return false;             }             finally             {                 if (pFeatCls != null)                 {                     pFeatCls.Dispose();                     pFeatCls = null;                 }             }         } We have reported similar issue before.  But we are still not able to solve this problem.  Any help will be greatly appreciated. ...

I was trying to select a layer from ArcGIS Online using the following code.  I can click the layer but pDialog.Items also return empty.  Any ideas? var pDialog = new ArcGIS.Desktop.Catalog.OpenItemDialog(); pDialog.MultiSelect = false; pDialog.Filter = "tables_all"; pDialog.ShowDialog(); var pItems = pDialog.Items; if (pItems == null) return; var pList = pItems.ToList<ArcGIS.Desktop.Core.Item>(); if (pList.Count < 1) return; var pItem = pList[0]; if (pItem == null) return; ...
