add a feature to my feature class

Hello every one ,

I'm trying to add a 2D feature (polygon) to my feature layer using ServiceFeatureTable so i tried to let the user to click the map to specify a new feature's location by listening to a click event on your map view, which in turn will call a function for adding a new feature. but my method doesn't seems good enough to work here's my code

public MainWindow()
{
InitializeComponent();
MyMapView.Map = new Map(Basemap.CreateTopographic());
MyMapView.GeoViewTapped += MymapView_GeoViewTapped;
}
private async void MymapView_GeoViewTapped(object sender, Esri.ArcGISRuntime.UI.Controls.GeoViewInputEventArgs e)
{
//get the click point in geographic coordinates
var mapClickPoint = e.Location;
var pointCollection = new Esri.ArcGISRuntime.Geometry.PointCollection(SpatialReferences.Wgs84);
pointCollection.Add(-109.048, 40.998);
pointCollection.Add(-102.047, 40.998);
pointCollection.Add(-102.037, 36.989);
pointCollection.Add(-109.048, 36.998);
//create a new polygon from the point collection
var polygon = new Esri.ArcGISRuntime.Geometry.Polygon(pointCollection);
var mapService = new LocalFeatureService(@"C:\Users\lolo\Documents\ArcGIS\3Dservitude.mpk");
await mapService.StartAsync();
var featureTable2DUri = new System.Uri($"{mapService.Url}/1");
var featureTable = new ServiceFeatureTable(featureTable2DUri);
await featureTable.LoadAsync();
//call the function that will add the new feature at this location
AddNewFeature(featureTable, mapClickPoint, 2018, polygon, 7000, 70000);
}

private async void AddNewFeature( ServiceFeatureTable featureTable,MapPoint location ,int servitude , Esri.ArcGISRuntime.Geometry.Polygon poly,int area , int lenght)
{

var attributes = new Dictionary<string, object>();
attributes.Add("servitude", servitude);
attributes.Add("polygone", poly);
attributes.Add("area", area);
attributes.Add("lenght", lenght);

//create a new feature in the GEOM2DServitudeGabarit table , pass in the attributes and geometry
var template = featureTable.FeatureTemplates.FirstOrDefault() ?? featureTable.FeatureTypes.FirstOrDefault(t => t.Templates.Any())?.Templates?.FirstOrDefault();
var newFeature = featureTable.CreateFeature(attributes, location);
await featureTable.AddFeatureAsync(newFeature);
var layer = new FeatureLayer(featureTable);

//push this update (apply edit) to the feature service
IReadOnlyList<EditResult> editResults = await featureTable.ApplyEditsAsync();
// check the results for errors
foreach (var r in editResults)
{
if (r.CompletedWithErrors)
{
Console.WriteLine("Edit to Object '" + r.ObjectId + "' failed: " + r.Error.Message);
}
}
}

i have a problem with (var newFeature = featureTable.CreateFeature(attributes, location);) looks doesn't support it although i have the right type parameters .and my code doesn't do any thing i join my mpk file .Any one can help please

thanks in advanced

cheers

Hi Manel,

I don't think LocalFeatureService yet has the capability of editing the feature from mpk. If you capture the url of the local feature service, only supported operation is the "Query". So it doesn't have the editing capabilities.

hi Yasmin ,

Okay now i understand , it's because of my basic licence of ArcMap that i use to generate my .mpk do you think that if i change the licence to standard will give me the ability to edit the features ? thanks in advance

cheers

Hello ,

i want to know with what i can replace (.mpk) to access to my geodatabase and edit features , knowing that i don't have arcGis pro so i can't use (.mmpk)

thanks
