ArcGISFeature.Attributes.Count is Much Lower than Expected

TheKenerson

Newbie question of the day. I am writing a simple data editor using Xamarin Forms .Here is my issue: In my sample, when I access a selected feature in my feature service, I get a count of 4 for my feature service and I am expecting a count of 49. 

The Count is displayed using the ArcGIS Feature.Attributes.Count Property.

So I can display and edit the attributes, but only a few of them. 

I have tried accessing other feature services from AGOL, and their counts are way off too. Its generally about 10% of the total number of attributes.

I think the data is okay as I can access/display/edit the same feature service in a webapp using REST with the JavaScript API I just cannot access the data in the .NET Runtime Xamarin Forms Application.

Anybody else come across this behavior?

Did you load the feature first? By default only a minimum set of attributes needed for rendering is requested from the server so you won't get the network overhead of downloading a bunch of attributes you might not ever see. Once you identify a feature and want to display it in the UI, you should "load" it first so that all the data is included:

if(feature is ILoadable)

    await ((ILoadable)feature).LoadAsync();
