Now I am generating a token for the FeatureService in my ArcGIS online services and using the same token to access the Feature Layers in my FeatureService but I am having invalid token error. Do youknow that the token for feature layers is different from the parent featureservice (one which ends with '/FeatureServer') or not? ... View more

Can you tell me how do you trim the url and how do you access to the home level of the service? I haven't tested similar case but it should work if you keep the token defined in every request. If you access to layers (webmap) via Document, remember to set Token property. If you are accessing to layer via Layer (ie. dynamic), make sure that Token gets set. If you are accessing via custom http call using ArcGISWebClient it doesn't automatically activate IdentityManger so it should be activated before using it. If you are accessing to layer via custom http call, remember to keep ?token=<token> defined. But if you tell how you access to the home level of the service, maybe I can give better pointers. Hi, thanks a lot for your reply. I really appreciate that 🙂 What I am doing is something like this 1. I present a dialog box in which I get user id and password for ArcGIS online 2. I use GetItemsAsync() function to get all the portal items Urls, secure and non secure both under that user's name. 3. I send one Url out of many to another function which removes the last two parts of the Url so that the Url ends with only '/services' e.g  http://xxxxx/arcgis/rest/services/US_Map/FeatureService to http://xxxxx/arcgis/rest/services 4. I perform JSON query on the resulting Url and create a tree like view in XAML. with the names and the URLs of the service. Then If a user clicks on one of the names. It creates a layer using the URL and then projects the layer on to the map. However when I perform Json query on the services Url aka http://xxxxx/arcgis/rest/services I only get the public services in response. I donot know how to incorporate token into the services home directory url so that I can see the private services as well. I will be grateful if you can shed some light on it. ... View more

Thanks Antti. This will be helpful ... View more

Hi, In the code example that you gave me, you added a Feature Layer which was in that FeatureService, not the whole FeatureService itself. If a FeatureService has multiple FeatureLayers then we will have to add them one by one using XAML tag <esri:FeatureLayer Thanks ... View more

Hi, Could you define your question in more detail, I think didn't understand it. Hi, Thanks a lot for your reply.  I have an ARcGIS 10.11 server in which I have MapService layers (Url ending with MapSErver) and FeatureService  layers (url ending with FeatureServer). I wanted to ask that whether ArcGIS api for wpf allows addition of layers whose URl end with FeatureServer directly on to the map? The reason why I ask is that I cannot find any function for initializing feature "services" in the API however there are functions for TiledMap services and DynamicMapServices listed in the API reference.

Humza, I have tried that but maybe I am putting it in the wrong spot or doing something else wrong.  I am attaching my code for both calling the get image process and the process itself.  Any help would be greatly appreciated.  Calling -(void) PrintPermitFinal { CAEAGLLayer *eaglLayer = (CAEAGLLayer *) self.mapView.layer;     eaglLayer.drawableProperties = @{                                      kEAGLDrawablePropertyRetainedBacking: [NSNumber numberWithBool:YES], kEAGLDrawablePropertyColorFormat: kEAGLColorFormatRGBA8                                      }; // reset buttons     [selfsettoInitialMapView]; // create image and pdf     UIImage *screenshot = [[UIImage alloc] initWithData:[self getImage]]; // use clip path Rect to clip image to right size CGImageRef imageref = CGImageCreateWithImageInRect([screenshot CGImage], clipRect);     screenshot = [UIImage imageWithCGImage:imageref]; //save image to photo album for testing only     UIImageWriteToSavedPhotosAlbum(screenshot,self,@selector(image:didFinishSavingWithError:contextInfo:),nil); //Send Image to Dictionary if (AppDelagate.PermitImages == nil)     { AppDelagate.PermitImages = [[NSMutableDictionaryalloc] init];     } NSString *Key= [selfCreatePermitID:[AppDelagate.GraphicToPrint.allAttributesvalueForKey:@"Full_Name"] AndAddress:[AppDelagate.GraphicToPrint.allAttributesvalueForKey:@"Owner_Address"]];     [AppDelagate.PermitImages setObject:screenshot forKey:Key]; self.tabBarController.selectedViewController = [self.tabBarController.viewControllersobjectAtIndex:1]; } Getting the image virtually unchanged from Bernese - (NSData *)getImage {     GLint width;     GLint height; glGetRenderbufferParameteriv(GL_RENDERBUFFER, GL_RENDERBUFFER_WIDTH, &width); glGetRenderbufferParameteriv(GL_RENDERBUFFER, GL_RENDERBUFFER_HEIGHT, &height);     NSInteger myDataLength = width * height * 4; // allocate array and read pixels into it.     GLubyte *buffer = (GLubyte *) malloc(myDataLength);     glReadPixels(0, 0, width, height, GL_RGBA, GL_UNSIGNED_BYTE, buffer); // gl renders "upside down" so swap top to bottom into new array. // there's gotta be a better way, but this works.     GLubyte *buffer2 = (GLubyte *) malloc(myDataLength);     for(int y = 0; y < height; y++)     {         for(int x = 0; x < width * 4; x++)         {             buffer2[((height - 1) - y) * width * 4 + x] = buffer[y * 4 * width + x];         }     } // make data provider with data.     CGDataProviderRef provider = CGDataProviderCreateWithData(NULL, buffer2, myDataLength, NULL); // prep the ingredients     int bitsPerComponent = 8;     int bitsPerPixel = 32;     int bytesPerRow = 4 * width; CGColorSpaceRef colorSpaceRef = CGColorSpaceCreateDeviceRGB(); CGBitmapInfo bitmapInfo = kCGBitmapByteOrderDefault; CGColorRenderingIntent renderingIntent = kCGRenderingIntentDefault; // make the cgimage     CGImageRef imageRef = CGImageCreate(width, height, bitsPerComponent, bitsPerPixel, bytesPerRow, colorSpaceRef, bitmapInfo, provider, NULL, NO, renderingIntent); // then make the uiimage from that     UIImage *myImage = [[UIImage alloc] initWithCGImage:imageRef];     NSData *iDat = UIImageJPEGRepresentation(myImage, 0);     CGImageRelease(imageRef); CGDataProviderRelease(provider);     CGColorSpaceRelease(colorSpaceRef);     free(buffer);     free(buffer2);     return iDat; } Cheers, Jeff Hi Jeff, does your print method gets called after user has pressed some button to take screenshot of the map ? if yes then kindly remove the first two lines of the code in print method and add them to a initialization method like didopenwebmap() or didloadmap() or your selfsettoInitialMapView() method  and try again. Also please make sure that before you take the screenshot there should be no popup being displayed on the map. Regards ... View more
