  • Feature layer selection

  This sample demonstrates how to select features in a feature layer by tapping a MapView.

  • Feature layer definition expression

  This sample demonstrates how to apply definition expression to a feature layer for filtering features. It also shows how to reset the definition expression.

  • Create a new feature collection layer

  This sample demonstrates how to create a new feature collection with several feature collection tables. The collection is displayed in the map as a feature collection layer.

  • Create a feature collection layer from a portal item

  This sample demonstrates opening a feature collection saved as a portal item.

  • Feature collection layer from query result

  This sample demonstrates how to create a feature collection layer to show a query result from a service feature table.

  • Feature layer dictionary renderer

  Demonstrates how to apply a dictionary renderer to a feature layer and display mil2525d graphics. The dictionary renderer creates these graphics using a mil2525d style file and the attributes attached to each feature within the geodatabase.

• Feature Tables

  • Service feature table (cache)

  • Render unique values

  This sample demonstrate how to use a unique value renderer to style different features in a feature layer with different symbols. Features do not have a symbol property for you to set, renderers should be used to define the symbol for features in feature layers. The unique value renderer allows for separate symbols to be used for features that have specific attribute values in a defined field.

  • Simple renderer

  This sample demonstrates how to create a simple renderer and add it to a graphics overlay. Renderers define the symbology for all graphics in a graphics overlay (unless they are overridden by setting the symbol directly on the graphic). Simple renderers can also be defined on feature layers using the same code.
