Hi, If I change something in css files of theme style folders, lets say a color, how to check that change on the WebAppp builder GUI? Do I need to close the webapp builder and run .bat file again? Or is there a simpler method? I noticed that sometimes changes in css files are not reflected by just refreshing the webpage. Many thanks

I am trying to publish a cached service through arcmap 10.1 to my arcgis online server, but after successful publication message, it is still not generating any cache. The message I am getting while viewing cache status is "Tile generation is not in progress or scheduled". Any idea how to fix this issue? Thanks

i want to display the global gravity data which is in the form of Kml. the link to the file is given below: ftp://topex.ucsd.edu/pub/global_grav_1min/global_grav.kmz‌ I wrote a small code using ARcGIS API for WPF and tried to initialize this kml file but I received this exception on running the code: 07/31/2014 13:37:39 | Fatal | App | Object reference not set to an instance of an object. STACKTRACE: at ESRI.ArcGIS.Client.Toolkit.DataSources.KmlLayer.Refresh() at ESRI.ArcGIS.Client.Toolkit.DataSources.KmlLayer.Initialize() at ESRI.ArcGIS.Client.GroupLayerBase.Initialize() at ESRI.ArcGIS.Client.Toolkit.DataSources.KmlLayer.backgroundWorker_RunWorkerCompleted(Object sender, RunWorkerCompletedEventArgs e) at System.ComponentModel.BackgroundWorker.OnRunWorkerCompleted(RunWorkerCompletedEventArgs e) at System.ComponentModel.BackgroundWorker.AsyncOperationCompleted(Object arg) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs) at MS.Internal.Threading.ExceptionFilterHelper.TryCatchWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler) | Object reference not set to an instance of an object. | | Dispatcher.CatchExceptionStatic => Dispatcher.CatchException => App.App_DispatcherUnhandledException As we can see that the exception is thrown by ArcGIS API internal functions. My code is given below: var kmlLayer = new KmlLayer { Url = new Uri(@"D:\global_grav.kml", UriKind.Absolute), ID = "Kml_Samples", VisibleLayers = new[] { "*" }, }; // I downloaded the file and converted it to kml kmlLayer.Initialize(); // this is where the exception is thrown. Any ideas about what might be causing this behavior? Any help would be highly appreciated. Thanks

Hi, I started learning ArcGIS API for JS today and I successfully displayed a simple basemap using the sample code provided in the first tutorial. However when I downloaded the 'Create Webmap' sample as a zip and tried to run it, it doesnot display any webmap except for the headers. I have tried changing web map IDs and although the sample runs in the sandbox, it displays blank screen when i download the html file and try to run it from my browser. Did anyone else experienced this issue? what can be the problem here. I have not modified the code in any way except for testing with different webmap IDs.

How do I add esri elevation service as a basemap in my native ios app. It is always asking for token when I add it with a url

Is there a way to add animation of weather data using ARcGIS SDK for WPF? I am in particular talking about these kinds of data visualizations http://earth.nullschool.net/#current/ocean/surface/currents/orthographic [ATTACH=CONFIG]31717[/ATTACH]

Yes, you are correct and thanks a lot for replying. But consider this scenario: I have a feature service which has 3 feature layers in it, a point feature layer, a polyline feature layer and a polygon feature layer. If I am making a user application on WPF, I donot think that it will be a good user experience for the user when he sees three sub feature layers instead of one in his/her application and then they have to add all these feature layers one by one to see the whole feature service. Thanks

How to added a service whose URL ends with FeatureServer (FeatureService) to a map using API for WPF? Please note that I am not talking about FeatureLayers but FeatureService. I know that Feature Layers can be added using FeatureLayer class, but I donot see any class for FeatureService like we have for TiledMapServiceLayers.

Dear Andrew, I can view my tile services by replacing services1 with 'tiles', 'tiles1', tiles2', 'tiles3' and 'tiles4. I am glad to know that you guys are working on this issue. Yes I can see all my services under 'services1' but I get an invalid url when I click on a tiled service, unless I replace services1 with the five variation of 'tiles' as I mentioned above.

Hello, How can I check programatically for a Layer(Tiled, Dynamic or Feature) whether a token is required to initialize it or not. I want to know this before I initialize it. I donot want to initialize it first and then view the error to know that I required a token for this service. I couldnot find any property in ArcGISTiledMapServiceLayer or ArcGISDynamicMapServiceLayer which can tell me that this service is secure.

Dear Thad, Thanks for the reply. I will use BeginInvoke and EndInvoke

If I use [HTML]http://services1.arcgis.com/<id>/ArcGIS/rest/services[/HTML], I can see all my feature services and tiled services listed in service directory. However if I click on any of the tiled services, It shows ' Invalid URL ' error. I have to change services1 to tiles and hit refresh in by browser in order to access the tiled service. Is this a bug? If yes then is there a work around for this, so that I donot have to change url manually everytime I want to see a tiled service? thanks

Dear goldenlimit, Thanks for the reply and the link. However I feel like even if we make our own GeoRSS, it would be tough to write code to display it on the map without any support from ESRI SDK.

Hi, I am implementing a function which will take username and ID of a person and then list the maps in the root folder and maps in the groups shared by that person in a separate UI. I am putting the results from both GetGroupAsync and GetItemsSync in an array. The idea is to call the new list box class constructor with the array as an argument after both async methods have finished. Now my problem is that where can I call the constructor of new class. There are three possibilities with three issues 1. put the nextUI = new Listboxconstructor(array); in the GetItemsAsync method. The problem is that I dont get the items from the GetGroupsAsync as that method is running in separate thread. 2. put the nextUI = new Listboxconstructor(array); in the GetGroupsAsync method. The problem is that I dont get the items from the GetItemsAsync as that method is running in separate thread. 3. put the nextUI = new Listboxconstructor(array); in the main thread. The problem is that I dont get the items from from any method as both methods are running in separate threads. Any workaround for this issue will be appreciated. Thanks
