Question

Hello every one ;

I have a feature class named departementalLevel , that contains layers , i need to display these layers using on a map suing arcGis runtime version 100.1 , so i generated a .mpk file from my feature class and now i need to display these layers from this mpk file , can i do this task ? and how i can do it  need a sample code please that explains

thanks in advanced

Hi Manel,

I have created a small application that starts the Local Server and add a mpk as an ArcGISMapImageLayer. It is pretty straight forward. Attached is the screen shot and project file. The mpk is located under the "bin\MPK" folder.

Hope that helps.

Hi Manel, There are a few ways you can troubleshoot a layer that is not loading. One of them is using LayerViewStateChanged. For ArcGISMapImageLayer, you can check sublayer load errors this way. public MainWindow() { InitializeComponent(); MyMapView.LayerViewStateChanged += MyMapView_LayerViewStateChanged; MyMapView.Map = new Map(Basemap.CreateTopographic()); } private async void MyMapView_LayerViewStateChanged(object sender, LayerViewStateChangedEventArgs e) { var error = e.LayerViewState.Error ?? e.Layer.LoadError; if (error != null) MessageBox.Show(error.Message); if(e.Layer is ArcGISMapImageLayer) { var layer = (ArcGISMapImageLayer)e.Layer; try { foreach (var sublayer in layer.Sublayers) await sublayer.LoadAsync(); } catch(Exception ex) { MessageBox.Show(ex.Message); } } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ If it were a rendering issue, you can supply a different renderer provided it matches the geometry type of your service. In snippet below, I only wanted to display the line geometry so I cleared the rest of the sublayers. var layer =(ArcGISMapImageLayer) MyMapView.Map.OperationalLayers.FirstOrDefault(); layer.Sublayers.Clear(); layer.Sublayers.Add(new ArcGISMapImageSublayer(1) { Renderer = new SimpleRenderer() { Symbol = new SimpleLineSymbol(SimpleLineSymbolStyle.DashDotDot, Colors.Blue, 2) } });‍‍‍‍‍‍‍‍‍ You can enable debugging from your ArcGIS Runtime Local Server Utility and use Fiddler or any web debugging tool. When using ArcGISMapImageLayer from a LocalServer, one of the requests should look like this which returns you an image. You should see the same image rendered in your runtime map.
