ArcGIS Pro version: 2.5 I have created a filegeodatabase with 2 Feature Classes and 1 Relationship Class with a Table (AttributedRelationshipClass). The AttributedRelationshipClass defines the link between those two featurelayers using GUIDs and a few properties for the relation. I used the ArcGis Pro sdk (c#) to add the feature classes to the map: var map = Project . Current . GetItems MapProjectItem > ( ) . FirstOrDefault ( e = > e . Name == name ) ; var lyrDocFromLyrxFile = new LayerDocument ( layerFile ) ; var cimLyrDoc = lyrDocFromLyrxFile . GetCIMLayerDocument ( ) ; var lcp = new LayerCreationParams ( cimLyrDoc ) ; LayerFactory . Instance . CreateLayer FeatureLayer > ( lcp , map , LayerPosition . AutoArrange ) ; I tried to add the table with: using ( var table = geodatabase . OpenDataset Table > ( relationshipName ) ) { StandaloneTableFactory . Instance . CreateStandaloneTable ( table , map , table . GetName ( ) ) ; } The datatype is then: esriDatasetType.esriDTTable. This resulted in these warnings: When I right click on the warning I get the option to add the table to the map. Then the table is added in the correct way with the datatype: esriDatasetType.esriDTRelationshipClass. Is it possible to do this with the ArcGIS Pro .NET sdk? Thanks, Tim

Is it possible to add an AttributedRelationshipClass Table to the map with esriDatasetType.esriDTRelationshipClass?

ArcGIS Pro version: 2.5

I have created a filegeodatabase with 2 Feature Classes and 1 Relationship Class with a Table (AttributedRelationshipClass).

The AttributedRelationshipClass defines the link between those two featurelayers using GUIDs and a few properties for the relation.

I used the ArcGis Pro sdk (c#) to add the feature classes to the map:

I tried to add the table with:

The datatype is then: esriDatasetType.esriDTTable.

This resulted in these warnings:

When I right click on the warning I get the option to add the table to the map. Then the table is added in the correct way with the datatype: esriDatasetType.esriDTRelationshipClass.

Is it possible to do this with the ArcGIS Pro .NET sdk?

Thanks,

Tim,

I haven't found a way to do this via the Pro SDK. We'll try to add support for this in a future ArcGIS Pro release.

Hi Tim,

While i can't find a way to make this relationship class work yet, there may be an alternative.

Instead of an attributed relationship class. create the table first and add 2 relationships with the other two featureclasses. and see if that works for you.

Gr,

Maarten

Hi Maarten van Hulzen ,

Thanks for the suggestion.

I added the table with the StandAloneTableFactory, which added the table to the map.

I tried adding the relationships with the "table.RelateTo()" method, but this only adds a virtual relationship and doesn't work for me. It states that this method is only used to create a Join object.

Do you have a code snippet to actually add a relationship?

Thanks,

Tim
