Yes, the error message is exactly the same as you mentioned. Not sure what should cause this but I might get rid of this issue by adding a group layer and just altering (adding/removing layers to the group layer) the layer collection of the group layer, rather than directly using the remove method on a map layer. I'm yet to confirm this by testing on a device although this works without issues on a visual studio simulator. ... View more

Hi Mike, Thanks for taking time to look into this. Please find the attached txt file with the code snippets where I add and remove the tiles. Few other observations: Adding a try/catch block doesn't help to catch the exception. I have even tried to add a check to see if I can get the layer ID property correctly and only then proceed to remove the tile but that hasn't helped either. So, it looked like a timing issue and therefore I went in and added delays/checked for one layer to be completely unloaded and then proceeded with removing the next one. But, none of these has helped. Strangely, in debug mode if I place a breakpoint on the remove line, it doesn't fail at all. However, when running without debugging, it throws the unhandled exception.When deployed on to a device on release mode, the app crashes. Please let me know if you want me to try any other workflow. Thanks, Suja ... View more

Code snippet below: Capture click event on the layer: myGraphicsLayer.MouseLeftButtonUp += new GraphicsLayer.MouseButtonEventHandler(myGraphicsLayer_MouseLeftButtonUp); void myGraphicsLayer_MouseLeftButtonUp(object sender, GraphicMouseButtonEventArgs e) {     InfoWindow infowin;     GraphicsLayer gl = (GraphicsLayer)sender as GraphicsLayer;        TextBlock tb = new TextBlock();        tb.Text = "My attribute content";        tb.Margin = new Thickness(2);        tb.FontSize = 14;        //set the info window and its content to the text block (whatever control you are using)                 infowin.Map = myMap;                 infowin.Anchor = myMap.ScreenToMap(e.GetPosition(myMap));                 infowin.Content = tb;                 infowin.IsOpen = true;                 infowin.Visibility = Visibility.Visible;        //add infowin to the layout        FrameworkElement parent = VisualTreeHelper.GetParent(myMap) as FrameworkElement;        ((Grid)parent).Children.Add(infowin); } ...

hi, Yes, I have used InfoWindow which popups on feature mouse click (raised by attaching a mouse click event on the layer). Have used silverlight controls (stackpanel/text block/dock panel,etc) to create the required attribute window which is set as the content of the InfoWindow. This InfoWindow's anchor point is set to the mouse clicked position and then the InfoWindow is added to the visual tree to place it on top of the map. All of this is done in code behind and works very well. The only drawback is it doesn't bring back attributes of multiple features as the standard identify behaviour, only the top layer feature is returned currently. But, I am sure there should be  a workaround for which I haven't spent time yet. Cheers. ... View more

Can someone from ESRI confirm if this is a bug? Thanks! ... View more

Thanks Jennifer. I figured that out. When I have a featurelayer, its LayerInfo has all the associated details. Thanks again. ... View more

Have you tried executing this task from the browser through the REST endpoint? Do you get your expected outfields there? Hi, The results from the REST endpoint on browser are exactly the same as I get through the code. Based on this link (http://support.esri.com/en/bugs/nimbus/TklNMDY2NzMx), I am assuming I need to set the input feature set's field definitions as shown in the code block below. Also, I have set all the possible parameters as possible. But, nothing has made any difference. All these are ignored in the output feature class. Code block:                   FeatureSet featureSet = new FeatureSet(graphicsToSerialize);                   featureSet.Fields = metroFLI.Fields;                   featureSet.GlobalIdFieldName = metroFLI.GlobalIdField;                   featureSet.ObjectIdFieldName = metroFLI.ObjectIdField;                   featureSet.DisplayFieldName = metroFLI.DisplayField;                     FeatureSet clipFeatureSet = new FeatureSet(GetExtentAsPolygon(_InterfaceFeatureExtent));                             Geoprocessor gpTask = new Geoprocessor("http://myarcgisserver/ArcGIS/rest/services/Geoprocess/GPServer/Clip");                                    gpTask.JobCompleted += new EventHandler<JobInfoEventArgs>(gpTask_JobCompleted);                     gpTask.Failed += new EventHandler<TaskFailedEventArgs>(gpTask_Failed);                     List<GPParameter> gpParameters = new List<GPParameter>();                     gpParameters.Add(new GPFeatureRecordSetLayer("Input_Features", featureSet));                                       gpParameters.Add(new GPFeatureRecordSetLayer("Clip_Features", clipFeatureSet));                     gpTask.ProcessSpatialReference = _Map.SpatialReference;                     gpTask.OutputSpatialReference = _Map.SpatialReference;                                                           gpTask.SubmitJobAsync(gpParameters); Code block of Job_Completed event: void gpTask_JobCompleted(object sender, JobInfoEventArgs e)         {             Geoprocessor gpTask = (Geoprocessor)sender as Geoprocessor;             gpTask.GetResultDataCompleted += new EventHandler<GPParameterEventArgs>(gpTask_GetResultDataCompleted);             gpTask.Failed += new EventHandler<TaskFailedEventArgs>(gpTaskGetResults_Failed);             gpTask.GetResultDataAsync(e.JobInfo.JobId, "Output_Feature_Class", e.UserState);         } Code block of GetResultDataCompleted: void gpTask_GetResultDataCompleted(object sender, GPParameterEventArgs e)         {             GPFeatureRecordSetLayer resultRecordSet = e.Parameter as GPFeatureRecordSetLayer;             FeatureSet resultFeatureSet = resultRecordSet.FeatureSet;                        IList<Graphic> resultGraphics = resultFeatureSet.Features; } As I said in my previous post, each graphic in my resultGraphics has FID, shape.leng and shape.length as their only attributes ignoring the whole set of attributes that the input_features had. Any further pointers is highly appreciated. Thanks. ... View more

Hi, I am not getting any user inputs for cutter polyline. I am converting an extent envelope to a polyline object and using that as a cutter polyline. This is done to cut a polyline graphic only to my required extent. However, the cut completed results has got only 1 result which means there was no cut perfomed. Can CutAsync method be used only when user digitizes a polyline as the cutter? I wouldn't assume so, but why is this behaviour? Thanks! ... View more
