Show predefined popups from a web map.

Show a popup screenshot

Use case

Many web maps contain predefined popups which are used to display the attributes associated with each feature layer in the map, such as hiking trails, land values, or unemployment rates. You can display text, attachments, images, charts, and web links. Rather than creating new popups to display information, you can easily access and display the predefined popups. The popup viewer control from the ArcGIS Toolkit currently supports label/value displays and plaintext HTML descriptions.

How to use the sample

Click on the features to prompt a popup that displays information about the feature.

How it works

  1. Create and load a Map using a URL.
  2. Use a 'GeoViewTapped' event for when the user clicks on the map.
  3. Use the IdentifyLayerAsync method to identify the top-most feature.
  4. Create a PopupManager using the Popup from the IdentifyLayerResult.
  5. Use the PopupManager to populate the PopupViewer UI element.

Relevant API

  • IdentifyLayerResult
  • Popup
  • PopupManager

About the data

This sample uses a feature layer that displays reported incidents in San Francisco.
