Humm, it seems the portal item was corrupted at some point. I repaired it so now it should work. ... View more

Running a new query returns new instances of the features so a test on layer.Graphics.Contains doesn't detect the duplicates. You can base your test on the objectID. By supposing the OBJECID of your feature layer is "ObjectId" you could try: var id = g.Attributes["ObjectId"]; if (!layer.Graphics.Any(graphic => graphic.Attributes["ObjectId"] == id)) ...... ...

As, with an ArcGISDynamicMapServiceLayer, nothing is loaded at client side (except an image), you have to query the server to get informations about the underlying features. You can look at the Identify sample. ... View more

Likely there is a mismatch in the referenced dll's. Double check that your main project and the project withthe printing controls reference the same ESRI dll's. ... View more

For generating a token you can use the IdentityManager.GenerateCredentialAsync method. You can also set the IdentityManager to challenge the user on the fly (sample) ... View more

Great you got this working:) Another thing I would like to know for setting own proxy do we need to have online premium service account or it is free of cost? The proxy code sample is free. Then to access to the services, the proxy doesn't change anything, the cost is only depending on the underlying services. So it's free if you access public KML files. ... View more

To programmatically generate a token, it seems that we must set the IdentityManager.Current.ChallengeMethod to the proper method which can give user/pw, and then call GenerateCredentialAsync from within the challenge method. You can also call GenerateCredentialAsync  out of the challenge method and then call AddCredential to register this credential with the IdentityManager. Once done, the IdentityManager will automatically use this credential to access to the specified arcgis resource (portal or server). Example of code snippet: private Task InitIdentityManager() {     var tcs = new TaskCompletionSource<bool>();     IdentityManager.Current.TokenGenerationReferer = "arcgis.com";     IdentityManager.Current.ChallengeMethodEx += SignInDialog.DoSignInEx; // activate the IM with the standard SignInDialog     IdentityManager.Current.GenerateCredentialAsync("http://www.arcgis.com/sharing/rest", "username", "password", (crd, error) =>     {         if (crd != null)         {             IdentityManager.Current.AddCredential(crd);             tcs.SetResult(true);         }         else             tcs.SetException(error ?? new Exception("Unknown error"));     });     return tcs.Task; } Instead of using GenerateCredentialAsync, you can also call GetCredentialAsync in order to challenge the user using the toolkit signInDialog. Something like: IdentityManager.Current.GetCredentialAsync("http://www.arcgis.com/sharing/rest", true, (crd, error) => {     if (crd != null)          IdentityManager.Current.AddCredential(crd); }); ...

What kind of Challenge method did you set? Is it a challenge method that generates a token progammatically or is there an UI? From your description, it looks as if a token was generated automatically by the challenge method but for a wrong user. In this case, the IM gets in a loop to give a chance to the user or to the program behind the challenge method to log in with the right user. However the loop is limited to 20 tentatives then the request fails (as if the user cancelled the sign in dialog). Note: if not already done, we can try to set a referer for the token generation. Something like IdentityManager.Current.TokenGenerationReferer = "arcgis.com". Though, that should not explain the error you reported. ... View more

Could you use fiddler to look at the error returned by the service at step 4)? That could give a clue. Note that if you access to hosted or federated services, you have to set a default referer for the token generation (something like IdentityManager.Current.TokenGenerationReferer = "arcgis.com") because hosted and federated services don't support tokens associated to an IP address. It's even a good practice to set a referer as soon as you access to a portal. ... View more

By default the legend tree nodes are expanded. You can change this behavior either by restyling the legend control, or, likely easier, by code on the event Legend.Refreshed: private void Legend_Refreshed(object sender, Legend.RefreshedEventArgs e) {     // Collapse all map layers in the legend.     e.LayerItem.IsExpanded = false;     // Collapse all sublayers     if (e.LayerItem.LayerItems != null)         foreach (var sublayerItem in e.LayerItem.LayerItems)             sublayerItem.IsExpanded = false; } ...
