Use case
A user can input a raw address into your app's search bar and zoom to the address location.
How to use the sample
For simplicity, the sample comes loaded with a set of suggested addresses. Choose an address from the suggestions or submit your own address to show its location on the map in a callout.
How it works
- Create a
LocatorTaskusing the URL to a locator service. - Set the
GeocodeParametersfor the locator task and specify the geocode's attributes. - Get the matching results from the
GeocodeResultusinglocatorTask.GeocodeAsync(addressString, geocodeParameters). - Create a
Graphicwith the geocode result's location and store the geocode result's attributes in the graphic's attributes. - Show the graphic in a
GraphicsOverlay.
