Not sure if that will give me what I need but I cannot seem to attach a handler to MapView #if IOS
.ConfigureMauiHandlers(handlers =>
{
handlers.AddHandler<Esri.ArcGISRuntime.Maui.MapView, MyMapViewHandler>();
handlers.AddHandler<ContentPage, ContentPageHandler>();
})
#endif I have this added in but the MyMapViewHandler never connects public class MyMapViewHandler : Esri.ArcGISRuntime.Maui.Handlers.MapViewHandler
{
protected MapView MapView => VirtualView as MapView;
protected override void ConnectHandler(Esri.ArcGISRuntime.UI.Controls.MapView nativeView)
{
base.ConnectHandler(nativeView);
//Still do not see a long press on nativeView
}
}

I am looking at the swift SDK. And it looks like swift has events that do not exist in .net. Which would seem how Field Maps is able to handle these behaviors

I want the magnifier. I want to be able to have the magnifier, let the user 'drop' at the location of the magnifier and somehow my app gets a notification that action (and location) occurred

If one does a GeoViewHolding on the map a magnifier pops up. In FieldMaps that gets handled and implements the Dropped pin behavior. I am trying to implement something similar but I cannot see what event is triggered after the magnifier appears and the user releases. The SDK seems to already be implementing the behavior for the magnifier, but what event handler does one implement to capture the release

I have tried using an upgrade to 200.7 and it still gives me the same issue. If I am logged in to ArcGIS Enterprise it will go into the ChallengeHandler with this Url: https://geocode-api.arcgis.com/arcgis/rest/services/World/GeocodeServer when the search bar is loaded. Entering credentials does nothing, it just loops through the ChallengeHandler over and over until I cancel and then there is no address search I think we have things setup correct in ArcGIS Enterprise, but if there is a guide that shows specifics I would be happy to review. We are able to do an address search from a WebMap

Yes absolutely. The idea that only the owner can create an offline area makes no sense. At lease allow other administrators, or have a special share around this. This makes using the entire offline area approach incredibly difficult.

I apologize for being unclear. I am not using an ApiKey if the user logs on. If they log in to ArcGIS Enterprise I do not set an ApiKey. When a user connects using this approach, when the Map opens with the SearchView an authentication is requested (i.e., ChallengeHandler invoked). The ServiceUri in the challenge is for the Geocoding Url. I did try using an ApiKey when the user does not log in via OAuth (SAML). Search works fine in this scenario. The user of course cannot sync, but search works fine because layer searches are offline and the ApiKey works for Geocoding Url.

Hi, I am really struggling with how one can use the SearchView in the toolkit on an ArcGIS Enterprise 11.1 portal. I am still at 200.6 for Mobile API and Toolkit. The problem is that the authentication does not seem to recognize that a logged in user can use location services. I have set in Portal the Configure utility services to use a AGOL user (user is a Creator/Admin). I can use the search in a web map and do a location search which works. However, when I open the map with the SearchView it will prompt for a login. If I try to enter my portal user, it will fail and ask again. I have logging so I can see that it is the geocode service Url that is requesting authentication. But it does not recognize the portal user as having permission. This makes the SearchView unusable. I have developed logic to read the Web Map configuration and create and add ISearchSource objects for each layer. Which works really well, but this permission to use locator is making it not useable as a search tool

After upgrading to 200.7 I am having issues with authentication. I basically now going to a non-stop loop of being asked to login. Logging shows it is the same exact service that is being requested in the ChallengeHandler. My 200.6 version of the app works as expected My process is to use the await ArcGISPortal.CreateAsync(new Uri(_portalUrl), true); to log into Portal. In 200.6 that is all that is required and then other services load properly. In 2007 I connect to the portal, I can see valid tokens in AuthenticationManager, but if I try to query a layer I am presented with the authentication dialog over and over

I just upgraded my app to use 200.7 and now when I try to load MapView it crashes. I am looking through getting started, don't see anything I need to change. I have been using net9.0 for a while on the 200.6 release System.InvalidOperationException: Unable to convert Esri.ArcGISRuntime.Maui.MapView to UIKit.UIView
