Routing and Driving Directions with Local Data

Question

Hello,
I am trying to return driving directions when using a GeoprocessorTask with a local dataset.
The example I am following is the "Point-to-point routing in ArcGIS Runtime for WPF" available here
http://www.arcgis.com/home/item.html?id=21a58d089764402e90ce127894dec94e.

Routing works just fine, however I am unable to get Routing Directions from the resulting FeatureSet.
Questions
1) Can one derive directions from a GeoprocessingTask and .gpk (if so how)?
2) Is the RouteTask and subsequent ArcGISServer Network Dataset the only way to return directions?

Ultimately my goal is to derive Routing Directions with a local dataset and not have to go through ArcGISServer.

Thanks in advance.

I was able to Successfully do this can you perhaps put your code up, might be able to help?

I have attached code in previous post.
The only other way I can think of it is to create a text file output from the Geoprocessing model using ModelBuilder
example here
http://resources.arcgis.com/en/help/main/10.1/index.html#//00570000009q000000

And then have a method that reads the output text; but it would seem that the directions can be exposed some other way

Below is code ............................................................................ private LocalGeoprocessingService geoprocessingService; private Geoprocessor geoprocessorTask; // Creating the service and starting public bool CreateNewRoute() { try { var source = ConfigUtils.ProjectLocation + ConfigurationManager.RouteLayer.SourceLayerName + ".gpk"; geoprocessingService = new LocalGeoprocessingService(source, GPServiceType.SubmitJob); geoprocessingService.StartAsync((x) => { if (x.Error != null) Log.Error(x.Error); }); return true; } catch (Exception ex) { Log.Error(ex); return false; } } // Solving route with input locations public bool SolveRoute() { try { geoprocessorTask = new Geoprocessor(geoprocessingService.UrlGeoprocessingService + "/Route"); geoprocessorTask.Failed += new EventHandler(GeoprocessorTaskFailed); geoprocessorTask.JobCompleted += new EventHandler(GeoprocessorTaskJobCompleted); routeTask = new RouteTask(geoprocessingService.UrlGeoprocessingService + "/Route"); routeTask.SolveCompleted += new EventHandler(RouteTaskSolveCompleted); routeTask.Failed += new EventHandler(RouteTaskFailed); List parameters = new List(); List inputLocations = new List() { new ESRI.ArcGIS.Client.Geometry.MapPoint(routeStartPoint.X, routeStartPoint.Y,esriMap.SpatialReference), new ESRI.ArcGIS.Client.Geometry.MapPoint(routeEndPoint.X, routeEndPoint.Y,esriMap.SpatialReference) }; FeatureSet featureSet = new FeatureSet(inputLocations); featureSet.GeometryType = GeometryType.Point; featureSet.SpatialReference = esriMap.SpatialReference; GPFeatureRecordSetLayer gpFeatureRecordSetLayer = new GPFeatureRecordSetLayer("Input_Locations", featureSet); parameters.Add(gpFeatureRecordSetLayer); geoprocessorTask.UpdateDelay = 2000; geoprocessorTask.SubmitJobAsync(parameters); return true; } catch (Exception ex) { Log.Error(ex); return false; } } //Route solved async, only features are returned, no way of deriving route direction objects private void GeoprocessorTaskJobCompleted(object sender, JobInfoEventArgs e) { try { geoprocessorTask.GetResultDataCompleted += (s1, e1) => { if (e1.Parameter is GPFeatureRecordSetLayer) { GPFeatureRecordSetLayer gpLayer = e1.Parameter as GPFeatureRecordSetLayer; var gphLayer = (GraphicsLayer)esriMap.Layers["LocalGraphicsLayer"]; gphLayer.ClearGraphics(); int i = 1; foreach (Graphic graphic in gpLayer.FeatureSet.Features) { Symbol sym = new SimpleLineSymbol() { Color = ConfigurationManager.RoutingColorBrush, Width = ConfigurationManager.RoutingWidth, }; graphic.Symbol = sym; gphLayer.Graphics.Add(graphic); } } }; geoprocessorTask.GetResultDataAsync(e.JobInfo.JobId, "Routes"); } catch (Exception ex) { Log.Error(ex); } }
