How to access a Feature Class rows without creating a feature layer or project item in ArcGIS Pro SDK?

Amadeus111 — Mon, 08 Nov 2021 13:27:47 GMT

I need to read a field's values from a Feature Class specifically it is a Feature Class in an enterprise geodatabase. The values will be populated as a Search Box suggestion source.

I can do that by creating a FeatureLayer via

LayerFactory.Instance.CreateFeatureLayer

and using RowCursor

using (ArcGIS.Core.Data.Table ProposedBoundariesTable = FLayer.GetTable()) { using (RowCursor rowCursor = ProposedBoundariesTable.Search()) { //collect the information } }

However, in some cases, I want end-users would be able to do make a quick search without creating a Feature Layer or project item. Is there a way to do that in ArcGIS Pro SDK?

@Amadeus111 Can you open the row cursor as below as described in snippets

// Open a featureClass (within a feature dataset or outside a feature dataset).
using (FeatureClass featureClass = geodatabase.OpenDataset<FeatureClass>("FeatureClassName")) 
 using (RowCursor rowCursor = featureClass .Search(new QueryFilter())){
}

@Wolf Thank you for your reply but those links are broken on my end.

I used @Aashis link and worked fine. I appreciate your help though.
