Class ArcGISFeature
Represents a Feature stored in an ArcGISFeatureTable.
Namespace: Esri.ArcGISRuntime.Data
Assembly: Esri.ArcGISRuntime.dll
Syntax
public sealed class ArcGISFeature : Feature, INotifyPropertyChanged, ILoadableRemarks
An ArcGISFeature can contain:
- A set of attributes that describe the real-world entity it represents.
- A geometry that defines its location and shape. The geometry might contain m-values, which are typically used for linear referencing.
- Zero or more feature attachments such as images or documents.
If you create a ServiceFeatureTable from the URL of a feature service, features in the table are initially in one of the following states:
- A minimum set of attributes are available in the table, and m-values are omitted. This is an optimization for faster rendering.
- All attributes defined by the service are available in the table, including m-values, which might be NaN.
The initial state of features is determined by the feature request mode of the table. For important details, see FeatureRequestMode.
By default, a query on ArcGISFeatures in a minimum state will return them in the same state. To access all attributes (or the m-values) of features returned by a query, you must load the features. You can do one of the following:
- Call LoadAsync() on each feature.
- Call LoadOrRefreshFeaturesAsync(IEnumerable<Feature>) and pass a collection of features to be loaded.
- Call QueryFeaturesAsync(QueryParameters, QueryFeatureFields) with the constant LoadAll, which returns all features in a fully loaded state.
For more information, see the class description for ServiceFeatureTable.
