Display selectable Points at runtime

Question

I am trying to get a Map that has selectable points that will navigate to a details page. These points are coming from a local database that can change often. The map will need to set these points at runtime. The map will also need to be offline. Any tips on what tools to use would be great. I have currently tried a map with graphics.

Also, you could put in each Graphic a KeyValuePair<string, object> that has some identifying information you can use to navigate to the details page. So after identifying the graphics, you can check if they have any keyvaluepair that matches what you want, and then navigate to your page, however your application handles that.

I know this might be to old for you now but in case others have a similar need.

A simple way to go about this using just Graphics and GraphicsOverlays could be for you to load the points from the database, create a MapPoint for each one, and a Graphic using each MapPoint as its geometry. You can then put them into a GraphicOverlay of your choice, and use the MapView.GeoViewTapped/GeoViewDoubleTapped events to capture when a user clicks on those Graphics/Points. You could then MapView.IdentifyGraphicsOverlaysAsync(...) or just have a collection of the same points that you use to reference the latlon and if the position you get from the GeoViewTapped events is in there, go to the detail's page related to that point.

Hi,

The approach with the best support for this scenario would be using a feature service and one of the offline map workflows (as mentioned in an earlier reply): https://developers.arcgis.com/net/offline-maps-scenes-and-data/.

A GraphicsOverlay might fit your needs, but you could also take a look at FeatureCollections which provide ToJson/FromJson methods for saving (they also support saving as portal items): https://developers.arcgis.com/net/wpf/api-reference/html/T_Esri_ArcGISRuntime_Data_FeatureCollection.htm.
