row.store throwing COMException: Error HRESULT E_FAIL

MK13 — Tue, 19 Nov 2024 22:10:12 GMT

My attempt to set and save the geometry on a point layer is throwing the COMException: Error HRESULT E_FAIL error on line 24, feat.Store(). @CharlesMacleod @Wolf @UmaHarano @GKmieliauskas any ideas?

Full error message is below:

ArcGIS.Core.Data.Exceptions.GeodatabaseException: 'A geodatabase exception has occurred.'

COMException: Error HRESULT E_FAIL has been returned from a call to a COM component.

Hi,

You could use Row.Store method without EditOperation callback only in OnRowChangedEvent implementation. More information here. There are not so many cases which need Store using.

The linked documentation states that you only need to utilise the edit operation callback when performing edits that span both GIS and non-GIS data. I am only updating GIS data so I assumed that I don't need to use a callback.

I have checked all Esri Community samples. There are 3 cases of using Store method. First method using inside EditOperation callback. Second method uses Store inside Geodatabase.ApplyEdits (sample MemoryGeodatabase). And third one as I wrote above is using Store in Row events without additional requirements (sample ModifyNewlyAddedFeatures). Rest of Store samples (6 from 😎 use first method.

I used Store method in my first add-ins, but now there is no Store usage in my code. It seems that is similar solution as in ArcObjects but it works different.
