Can you access feature layers without a map? If not, can you delete a map from a project or create a temporary map?

Question

I need to access the attributes from various feature classes and, to the best of my knowledge, you can only do this through a feature layer loaded into a map. I am currently trying to create a map object, run the needed processes, then delete that map object. Is there a way to do this "behind the scenes" or without having an active map? I cannot find anything on being able to delete that map object.

Hi...did you ever find a solution to this?

I'm finding the same odd issue that isn't quite understood when trying to explain. I have an old .lyr file that was saved from a SQL server query (Query Layer).  I have since converted that to a lyrx file and I just want to use that lyrx file to search through the data...without adding it to a map.  In ArcObjects it was simple to get a FeatureLayer loaded from a lyr file.  Not only that, any set definition queries came along with it so you didn't have to wire that part up when searching the 'raw' feature class underlying the FeatureLayer.

Any ideas would be great!

Thanks

Hi Scott,

Once you fetch an individual feature, you can certainly view and edit the attribute data.  Here is an example showing how to modify a row: ProSnippets Geodatabase · Esri/arcgis-pro-sdk Wiki · GitHub

I hope this helps,

That method does not allow you to get to the attribute data associated with the feature. According to the SDK, that can only be done through an Inspector() loaded with a feature layer, ProConcepts Editing · Esri/arcgis-pro-sdk Wiki · GitHub
