The method below shows how I create a notification. I append a new item to the UserInfo dictionary.
private UNNotificationRequest CreateNotification(Geofence geofence)
{
var content = new UNMutableNotificationContent();
content.Title = "title";
content.Subtitle = "subtitle";
content.Body = "This is the message body of the notification.";
content.Badge = 2;
content.UserInfo.Append(new KeyValuePair<NSObject, NSObject>((NSString)"id", (NSString)"bla"));
var trigger = UNTimeIntervalNotificationTrigger.CreateTrigger(1, false);
var request = UNNotificationRequest.FromIdentifier("test1", content, trigger);
return request;
}
The problem is as follows:
public override void DidReceiveNotificationResponse(UNUserNotificationCenter center, UNNotificationResponse response, Action completionHandler)
{
foreach (var item in response.Notification.Request.Content.UserInfo)
{
}
// Inform caller it has been handled
completionHandler();
}
The UserInfo dictionary is always empty. Why is that and how can I fix this?
You need to get the logic in the switch statement
public override void DidReceiveNotificationResponse(UNUserNotificationCenter center, UNNotificationResponse response, Action completionHandler)
{
// Take action based on Action ID
switch (response.ActionIdentifier)
{
case "reply":
// Do something
break;
default:
// Take action based on identifier
if (response.IsDefaultAction)
{
// Handle default action...
var item = response.Notification.Request.Content.UserInfo;
}
else if (response.IsDismissAction)
{
// Handle dismiss action
}
break;
}
// Inform caller it has been handled
completionHandler();
}
Update
It seems that you add UserInfo in wrong way . Check the following code
content.UserInfo = NSDictionary.FromObjectAndKey(new KeyValuePair<NSObject, NSObject>((NSString)"id", (NSString)"bla"));

I need to run some address validation on Customer Location addresses using a 3rd party API to determine if the address is residential or commercial. This validation should run whenever an address field is changed. In other words, the validation should be run in the Address_RowUpdated event handler.
Because the function is calling a 3rd party API, I believe that it should be done in a separate thread, using PXLongOperation so that it does not hold up address saving and fails gracefully if the API is unavailable or returns an error.
However, I am not sure if the architecture of running a long operation within an event handler is supported or if a different approach would be better.
Here is my code.
public class CustomerLocationMaint_Extension : PXGraphExtension<CustomerLocationMaint>
{
protected virtual void Address_RowUpdated(PXCache sender, PXRowUpdatedEventArgs e)
{
PX.Objects.CR.Address row = (PX.Objects.CR.Address)e.Row;
if (row != null)
{
Location location = this.Base.Location.Current;
PXCache locationCache = Base.LocationCurrent.Cache;
PXLongOperation.StartOperation(Base, delegate
{
RunCheckResidential(location, locationCache);
});
this.Base.LocationCurrent.Cache.IsDirty = true;
}
}
protected void RunCheckResidential(Location location, PXCache locationCache)
{
string messages = "";
PX.Objects.CR.Address defAddress = PXSelect<PX.Objects.CR.Address,
Where<PX.Objects.CR.Address.addressID, Equal<Required<Location.defAddressID>>>>.Select(Base, location.DefAddressID);
FValidator validator = new FValidator();
AddressValidationReply reply = validator.Validate(defAddress);
AddressValidationResult result = reply.AddressResults[0];
bool isResidential = location.CResedential ?? false;
if (result.Classification == FClassificationType.RESIDENTIAL)
{
isResidential = true;
} else if (result.Classification == FClassificationType.BUSINESS)
{
isResidential = false;
} else
{
messages += "Residential classification is: " + result.Classification + "\r\n";
}
location.CResedential = isResidential;
locationCache.Update(location);
Base.LocationCurrent.Update(location);
Base.Actions.PressSave();
// Display relevant messages
if (reply.HighestSeverity == NotificationSeverityType.SUCCESS)
String addressCorrection = validator.AddressCompare(result.EffectiveAddress, defAddress);
if (!string.IsNullOrEmpty(addressCorrection))
messages += addressCorrection;
}
PXSetPropertyException message = new PXSetPropertyException(messages, PXErrorLevel.Warning);
PXLongOperation.SetCustomInfo(new LocationMessageDisplay(message));
//throw new PXOperationCompletedException(messages); // Shows message if you hover over the success checkmark, but you have to hover to see it so not ideal
}
public class LocationMessageDisplay : IPXCustomInfo
{
public void Complete(PXLongRunStatus status, PXGraph graph)
{
if (status == PXLongRunStatus.Completed && graph is CustomerLocationMaint)
{
((CustomerLocationMaint)graph).RowSelected.AddHandler<Location>((sender, e) =>
{
Location location = e.Row as Location;
if (location != null)
{
sender.RaiseExceptionHandling<Location.cResedential>(location, location.CResedential, _message);
}
});
}
}
private PXSetPropertyException _message;
public LocationMessageDisplay(PXSetPropertyException message)
{
_message = message;
}
}
}
UPDATE - New Approach
As suggested, this code now calls the LongOperation within the Persist method.
protected virtual void Address_RowUpdated(PXCache sender, PXRowUpdatedEventArgs e)
{
PX.Objects.CR.Address row = (PX.Objects.CR.Address)e.Row;
if (row != null)
{
Location location = Base.Location.Current;
LocationExt locationExt = PXCache<Location>.GetExtension<LocationExt>(location);
locationExt.UsrResidentialValidated = false;
Base.LocationCurrent.Cache.IsDirty = true;
}
}
public delegate void PersistDelegate();
[PXOverride]
public virtual void Persist(PersistDelegate baseMethod)
{
baseMethod();
var location = Base.Location.Current;
PXCache locationCache = Base.LocationCurrent.Cache;
LocationExt locationExt = PXCache<Location>.GetExtension<LocationExt>(location);
if (locationExt.UsrResidentialValidated == false)
{
PXLongOperation.StartOperation(Base, delegate
{
CheckResidential(location);
});
}
}
public void CheckResidential(Location location)
{
CustomerLocationMaint graph = PXGraph.CreateInstance<CustomerLocationMaint>();
graph.Clear();
graph.Location.Current = location;
LocationExt locationExt = location.GetExtension<LocationExt>();
locationExt.UsrResidentialValidated = true;
try
{
// Residential code using API (this will change the value of the location.CResedential field)
} catch (Exception e)
{
throw new PXOperationCompletedWithErrorException(e.Message);
}
graph.Location.Update(location);
graph.Persist();
}
PXLongOperation is meant to be used in the context of a PXAction callback. This is typically initiated by a menu item or button control, including built-in actions like Save.
It is an anti-pattern to use it anytime a value changes in the web page. It should be used only when a value is persisted (by Save action) or by another PXAction event handler. You should handle long running validation when user clicks on a button or menu item not when he changes the value.
For example, the built in Validate Address feature is run only when the user clicks on the Validate Address button and if validated requests are required it is also run in a Persist event called in the context of the Save action to cancel saving if validation fails.
This is done to ensure user expectation that a simple change in a form/grid value field doesn't incur a long validation wait time that would lead the user to believe the web page is unresponsive. When the user clicks on Save or a specific Action button it is deemed more reasonable to expect a longer wait time.
That being said, it is not recommended but possible to wrap your PXLongOperation call in a dummy Action and asynchronously click on the invisible Action button to get the long operation running in the proper context from any event handler (except Initialize):
using PX.Data;
using System.Collections;
namespace PX.Objects.SO
{
public class SOOrderEntry_Extension : PXGraphExtension<SOOrderEntry>
{
public PXAction<SOOrder> TestLongOperation;
[PXUIField(DisplayName = "Test Long Operation", Visible = false, Visibility = PXUIVisibility.Invisible)]
[PXButton]
public virtual IEnumerable testLongOperation(PXAdapter adapter)
{
PXLongOperation.StartOperation(Base, delegate ()
{
System.Threading.Thread.Sleep(2000);
Base.Document.Ask("Operation Done", MessageButtons.OK);
});
return adapter.Get();
}
public void SOOrder_OrderDesc_FieldUpdated(PXCache sender, PXFieldUpdatedEventArgs e)
{
if (!PXLongOperation.Exists(Base.UID))
{
// Calling Action Button asynchronously so it can run in the context of a PXAction callback
Base.Actions["TestLongOperation"].PressButton();
}
}
}
}
In the Azure app service mobile backend service, REST API requests are handled by TableController implementation. These methods can be invoked by using corresponding methods available in client SDKs. So, i can query for a particular entity and update its status from the client side.
But how to invoke them in the server side or within the same controller? For example, if I want to query for a particular todoItem and update its status from some custom method here like
Use LookUp(id) to get the item
Update the status
Use UpdateAsync(id, item)
Here I don't know how to create a Delta object of TodoItem to call UpdateAsync(id, patch) method.
public class TodoItemController : TableController<TodoItem>
{
protected override void Initialize(HttpControllerContext controllerContext)
{
base.Initialize(controllerContext);
initrackerserviceContext context = new initrackerserviceContext();
DomainManager = new EntityDomainManager<TodoItem>(context, Request);
}
// GET tables/TodoItem
public IQueryable<TodoItem> GetAllTodoItems()
{
return Query();
}
// GET tables/TodoItem/48D68C86-6EA6-4C25-AA33-223FC9A27959
public SingleResult<TodoItem> GetTodoItem(string id)
{
return Lookup(id);
}
// PATCH tables/TodoItem/48D68C86-6EA6-4C25-AA33-223FC9A27959
public Task<TodoItem> PatchTodoItem(string id, Delta<TodoItem> patch)
{
return UpdateAsync(id, patch);
}
// POST tables/TodoItem
public async Task<IHttpActionResult> PostTodoItem(TodoItem item)
{
TodoItem current = await InsertAsync(item);
return CreatedAtRoute("Tables", new { id = current.Id }, current);
}
// DELETE tables/TodoItem/48D68C86-6EA6-4C25-AA33-223FC9A27959
public Task DeleteTodoItem(string id)
{
return DeleteAsync(id);
}
}
Just use the standard Entity Framework mechanisms. For instance, to find and update a record with a status, you can just use the context:
var item = await context.TodoItems.Where(i => i.Id.Equals(myId)).FirstOrDefaultAsync<TodoItem>();
if (item != null) {
item.Complete = true;
context.Entry(item).State = EntityState.Modified;
await context.SaveChangesAsync();
}
My EF coding is not the greatest ad-hoc, but you should get the idea. Just do the Entity Framework thing.
It's better to use TableController.ReplaceAsync() method that is already implemented for us here in the source code of EntityDomainManager.
var item = Lookup(item.Id).Queryable.FirstOrDefault();
if (item != null)
{
item.Complete = true;
item = await ReplaceAsync(item.Id, item);
}
The ReplaceAsync() method correctly handles the exceptions, so I would not recommend working directly with the EF context.
I'm trying to retrieve user data from Parse (xamarin.ios using c#). I'm using an async method with await. My challenge is,each time I navigate to the tableView in the app, which should populate the user data in question,the table is always empty.
I would like to wait until the results have been returned before proceeding with the other portion of code.I have tried to use the ContinueWith() function but constantly ran into a build error -
Cannot implicitly convert type 'void' to System.Collections.Generic.IEnumerable<Parse.ParseObject>
My Questions:
Is this the best way to wait for the result?
How do I solve the build error?
Here is my current implementation:
public async void retrieveData(string username)
{
try
{
this.requests.ClearRequests();
refreshed = false;
var query = ParseObject.GetQuery("Requests").WhereEqualTo("username", username);
IEnumerable<ParseObject> results = await query.FindAsync().ContinueWith(t =>{
if(results != null)
{
foreach(ParseObject parseObject in results)
{
UserRequest request = new UserRequest();
request.objectId = parseObject.ObjectId;
request.make = parseObject.Get<string> ("item1");
request.model = parseObject.Get<string> ("item2");
request.year = parseObject.Get<string> ("item3");
request.userName = parseObject.Get<string> ("username");
this.requests.addRequest (request);
}
refreshed = true;
}
});
}
catch(ParseException e) {
Console.WriteLine (e.Message + e.StackTrace);
}
}
You shouldn't need a ContinueWith...that's what the await should handle.
await waits on a Task and then brings back the result with the proper return type. ContinueWith returns a Task, so you would have to grab the Result from the task to make it usable.
For more on this type of thing, you may want to check out Difference between await and ContinueWith
You can try something like this.
public async void retrieveData(string username, )
{
try
{
this.requests.ClearRequests();
refreshed = false;
var query = ParseObject.GetQuery("Requests").WhereEqualTo("username", username);
IEnumerable<ParseObject> results = await query.FindAsync();
if(results != null)
{
foreach(ParseObject parseObject in results)
{
UserRequest request = new UserRequest();
request.objectId = parseObject.ObjectId;
request.make = parseObject.Get<string> ("item1");
request.model = parseObject.Get<string> ("item2");
request.year = parseObject.Get<string> ("item3");
request.userName = parseObject.Get<string> ("username");
this.requests.addRequest (request);
}
refreshed = true;
}
//This is your refresh method for your TableView
this.RefreshTableView();
//or, if in iOS
NSNotificationCenter.DefaultCenter.PostNotificationName("resultsRetrieved", null);
}
catch(ParseException e) {
Console.WriteLine (e.Message + e.StackTrace);
}
}
To show the results in the tableView, I would recommend moving the refreshing of the tableView to a separate method that gets triggered synchronously after the results have been retrieved and parsed. This is shown with the this.RefreshTableView() call above.
If in iOS on Xamarin, another option is to post a notification to the NSNotificationCenter (the Xamarin documentation for which is here). Use the PostNotificationName part seen above instead and then add an observer in the ViewControllers that you want to be dependent on the data. This is done as follows:
Make a notificationToken object:
NSObject notificationToken;
Then in your setup method (you could put this inside of your ViewDidLoad):
void Setup ()
{
notificationToken = NSNotificationCenter.DefaultCenter.AddObserver ("resultsRetrieved", RefreshData);
}
Make your RefeshData method:
void RefreshData (NSString notifString)
{
this.tableView.ReloadData();
}
And then, make sure you dispose of the notification observer when you tear down the class
void Teardown ()
{
NSNotificationCenter.DefaultCenter.RemoveObserver (notificationToken);
}
I had a similar issue so started using callbacks. I'm using them in Xamarin.Android, pretty sure they're available in Xamarin.iOS.
Method that starts the task method - Note I am passing in a method of this class as a parameter
private async void updatedData()
{
await Utils.DataTasks.getNewLiveTips(populateTipsList);
}
Method that calls for data from server
public class DataTasks
{
public static async Task getAllData(Action<IEnumerable<ParseObjects>> callback) {
var query = new ParseQuery<ParseObjects>().OrderByDescending("updatedAt").Limit(5);
IEnumerable<ParseObjects> parseTips = await query.FindAsync();
foreach (var tip in parseTips)
{
// Save data to DB if needed
}
callback(parseTips);
}
Method I passed as parameter in the first instance is now called
private void populateTipsList(IEnumerable<ParseObjects> results)
{
mAdapter = new TipAdapter(this.Activity, results);
mRecyclerView.SetAdapter(mAdapter);
refresher.Refreshing = false;
}
Is it possible to delete entity while same is still in plugin update transaction?
It seems following code is not working. I need to delete entity when its get updated and some other circumstances
Something like:
protected void ExecutePosAnnotationtUpdate(LocalPluginContext localContext)
{
if (localContext == null)
{
throw new ArgumentNullException("localContext");
}
if (localContext.PluginExecutionContext.Depth > 1) return;
Entity postEntityImage = null;
if (localContext.PluginExecutionContext.PostEntityImages.Contains("PostImage"))
{
if (localContext.PluginExecutionContext.PostEntityImages["PostImage"] != null)
{
postEntityImage = localContext.PluginExecutionContext.PostEntityImages["PostImage"];
}
}
Entity preEntityImage = null;
if (localContext.PluginExecutionContext.PreEntityImages.Contains("PreImage"))
{
if (localContext.PluginExecutionContext.PreEntityImages["PreImage"] != null)
{
preEntityImage = localContext.PluginExecutionContext.PreEntityImages["PreImage"];
}
}
if ((bool)postEntityImage.Attributes["isdocument"])
{
if ( some condition )
localContext.OrganizationService.Delete(postEntityImage.LogicalName, postEntityImage.Id);
}
}
`
Since you're updating, the record is there in Target.
public void Execute(IServiceProvider serviceProvider)
{
var context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
var serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
var service = serviceFactory.CreateOrganizationService(context.UserId);
var target = context.InputParameters["Target"] as Entity;
var condition = /* whatever */
if(condition)
{
service.Delete(target.LogicalName, target.Id);
}
}
Works as expected when attached to Update message, Post-Operation, Asynchronous. Works inside the Sandbox, also.
Records will not disappear at once, it takes some time (~20 seconds on my on-premise playground). If you make it Synchronous it will still work but alerts are going to come up because data disappears while being handled by the CRM during the update.
I have an Azure Mobile service coded in .net Web API. I have a TableController. I want that table controller to be able to insert multiple persons, not just one person with from the client with InsertAsync(myPerson). I have the following code in the TableController:
[RequiresAuthorization(AuthorizationLevel.Admin)]
public async Task<bool> InsertPersons(List<Person> values)
{
try
{
foreach (var item in values)
{
var current = await InsertAsync(item);
}
return true;
}
catch (System.Exception)
{
return false;
}
}
The problem is in the client. Because it is strongly typed it only allows me to insert one item at a time. How must I call the server from the client? Do I have to write a Custom Api Controller and call it with mobileService.InvokeApiAsync? If so, how can I get access to my database from a Custom API Controller that doesn't inherit from TableController?
Thank you so much!
The helper methods in the TableController<T> base class assume that the insert operations apply to a single object - and the InsertAsync method in the client also assumes the same. So even though you can define in a table controller a method that takes an array (or list) of Person, you won't be able to call it via the client SDK (at least not without some heavy-lifting using a handler, for example).
You can, however, create a custom API which takes such a list. And to insert the multiple items from the API, you can access the context directly, without needing to go through the helper methods from the table:
public class PersonController : ApiController
{
test20140807Context context;
protected override void Initialize(HttpControllerContext controllerContext)
{
base.Initialize(controllerContext);
this.context = new test20140807Context();
}
[HttpPost]
public async Task<bool> InsertPersons(List<Person> values)
{
foreach (var value in values)
{
if (string.IsNullOrEmpty(value.Id))
{
value.Id = Guid.NewGuid().ToString();
}
}
try
{
this.context.People.AddRange(values);
await this.context.SaveChangesAsync();
return true;
}
catch (System.Exception ex)
{
Trace.WriteLine("Error: " + ex);
return false;
}
}
}
And on the client:
private async void btnTest_Click(object sender, RoutedEventArgs e)
{
var items = new Person[]
{
new Person { Name = "John Doe", Age = 33 },
new Person { Name = "Jane Roe", Age = 32 }
};
try
{
var response = await App.MobileService.InvokeApiAsync<Person[], bool>("person", items);
Debug.WriteLine("response: " + response);
}
catch (Exception ex)
{
var str = ex.ToString();
Debug.WriteLine(str);
}
}
From Carlos Figueira's post on inserting multiple items at once in azure mobile services, it looks like what you need to do is create another table called AllPersons. In your client, the AllPersons object would have a Persons array member. In your server side script for the AllPersons insert, you iterate through the AllPersons.Persons and insert into the table one by one.
