Access load status

This code sample is available for these platforms:
View Sample on GitHub

Determine the map's load status which can be: NotLoaded, FailedToLoad, Loading, Loaded.


Use case

Knowing the map's load state may be required before subsequent actions can be executed.

How to use the sample

The load status of the map will be displayed as the sample loads.

How it works

  1. Create a Map and add it to a MapView.
  2. Use the Map.LoadStatusChanged event to listen for changes in the map's load status.

The LoadStatus is Loaded when any of the following criteria are met:

  • The map has a valid spatial reference.
  • The map has an an initial viewpoint.
  • One of the map's predefined layers has been created.

Relevant API

  • Map
  • ILoadable
  • MapView
