Is there Any alternate of microchart nugets to implement Graph Chart? microchart Nugets increase package size .
Hello Team,
I am facing this The "XamlCTask" task failed unexpectedly. problem after adding the xamarin.forms.maps package to my application.
Waiting for your response.
Hello Everyone,
I think posting this information here will help Xamarin.Forms developers reduce their development time for building beautiful mobile apps.
The Essential UI Kit for Xamarin.Forms includes 35+ elegantly designed XAML pages, which can be used for modern mobile apps. You can use these pages to build your application from scratch or add required pages to your current applications. All the pages are based on the MVVM pattern, which makes it easy to integrate your business logic. The kit comes with a powerful Visual Studio extension, so adding new pages is like adding a ContentPage.
More pages are coming to this UI kit in the near future!
You can find all the resources to get started with this new product in the following blog post.
https://www.syncfusion.com/blogs/post/the-essential-ui-kit-for-xamarin-forms-is-ready-to-use.aspx
I encourage you to try using our Essential UI Kit to build your Xamarin.Forms apps faster and then give us your feedback.
Thanks,
Prabakaran
I'm trying to use XamarinEssentials to get sensors reading at the highest speed possible.
Trying to use SensorSpeed.Fastest, I'm still getting all the events on the Main/UI thread (which is for sure not the fastest way).
I hoped to find a way to get the events on other threads so I can collect more samples from the sendors.
Any sensor that we start with SensorSpeed.Fastest is claimed to "Get the sensor data as fast as possible (not guaranteed to return on UI thread)."
Tried the following code on multiple devices (and different sensors). Always same results (all notifications are always in the main/ui thread).
Am I doing anything wrong?
Note:
Here is a code snippet that demonstrated my issue:
Magnetometer.ReadingChanged += Magnetometer_ReadingChanged;
Magnetometer.Start(SensorSpeed.Fastest)
...
void Magnetometer_ReadingChanged(object sender, MagnetometerChangedEventArgs e)
{
** // This always received on ThreadId=1 (Main/UI Thread)...**
Console.WriteLine($"Thread: {Thread.CurrentThread.ManagedThreadId},. Reading: {data.MagneticField.}");
}
I want to Open picker list (picker.focus()) whenever I click on Frame.
I am using Xamarin forms with Prism Framework.
I have tried with below code but getting item object , not picker object.
<ListView.Behaviors>
<behavior:EventToCommandBehavior
EventName="ItemTapped"
Command="{Binding ApplyLeaveInfoCommand}"
EventArgsParameterPath="Item"/>
</ListView.Behaviors>
So Can I get picker.focus() after click on listview Item ???
Complete code:-
<ListView.ItemTemplate>
<Grid.RowDefinitions>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
</Grid.ColumnDefinitions>
<Image Source="{Binding ImageSource}" Aspect="AspectFit" Grid.Row="0" Grid.Column="1" Grid.RowSpan="2" VerticalOptions="CenterAndExpand" />
</Grid><Frame.GestureRecognizers>
<ClickGestureRecognizer Command="{Binding ApplyLeaveInfoCommand}"
CommandParameter="{Binding .}"
/></Frame.GestureRecognizers>
</Frame>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
I am trying a simple Azure function SignalR connection using Xamarin C# client.
The sample Javascript conenction to Azure function works fine.
[FunctionName("negotiate")]
public static SignalRConnectionInfo GetSignalRInfo(
[HttpTrigger(AuthorizationLevel.Anonymous, "post")] HttpRequest req,
[SignalRConnectionInfo(HubName = "chat")] SignalRConnectionInfo connectionInfo)
{
Console.WriteLine($"UserInfo: ");
return connectionInfo;
}
The client Javascript code works fine
const connection = new signalR.HubConnectionBuilder()
.withUrl(`${apiBaseUrl}/api`)
.configureLogging(signalR.LogLevel.Information)
.build();
connection.on('newMessage', newMessage);
connection.onclose(() => console.log('disconnected'));
console.log('connecting...');
connection.start()
.then(() => data.ready = true)
.catch(console.error);
It's my Xamarin forms c# code that hangs on StartAsync() call
hubConnection = new HubConnectionBuilder()
//.WithUrl($"http://signalrdemomsph.azurewebsites.net/chatHub")
.WithUrl($"http://10.0.2.2:7071/api/")
//.WithUrl($"https://10.0.2.2:44398/chatHub")
.Build();
hubConnection.On<string>("negotiate", (user) =>
{
Messages.Add(new SignalRMessage() { User = Name, Message = $"{user} has joined the chat", IsSystemMessage = true });
});
hubConnection.On<string, string>("ReceiveMessage", (user, message) =>
{
Messages.Add(new SignalRMessage() { User = user, Message = message, IsSystemMessage = false, IsOwnMessage = Name == user });
});
try
{
await hubConnection.StartAsync();
}
catch(Exception e)
{
Console.WriteLine(e.StackTrace);
}
await hubConnection.InvokeAsync("negotiate", Name);
I read here at Stackoverflow it could be a deadlock issue as I get an exception after a minute or so at the above code Console.Writeline(e.StackTrace)

It only happens in Debug, but in Release i can deploy and run the app just fine.
Why is this happening?
This morning i installed the Android SDK 10.0 and I suspect it started after that, so now I uninstalled it, but I still can't deploy because of the same error.
Other apps from the same PC can be deployed just fine, so I don't get it...
I did check this out
https://docs.microsoft.com/en-us/xamarin/android/errors-and-warnings/adb0030
but I don't even have my app installed on the device...
Thanks

Hello there!
Right now, my apps can show some reports in PDF format: I have a WebApi call that opens a Crystal Report, populate it with updated data, save as PDF, and put it on a shared folder to see it using that popular javascript web viewer through a WebView on the App.
But our customer wants to watch the Crystal Report itself, because it has navigation (sub-reports, line details data...), so PDF is not good enough.
Asking to our SAP expert, he said that there is a lot of plugins to see Crystals on PC and mobile phones, so it can be easy to find a plugin or something to put a report in our APP. So I was looking for some examples or info, and I only found how to do on VS with C#, but no clue on how to show on a Xamarin page or how to open it on a third-party APP (if any).
Could you give me some advices, point me on the right direction or a link to a blog or something to do that? Or what the customer/expert wants is impossible right now?
Thank you.

Hi,
I have a Xamarin.Forms application with FontAwesome for iOS & Android. Now I
want to use it in macOS also.
I added this to the Info.plist:
<key>Fonts provided by application</key>
<array>
<string>FontAwesome5Regular.otf</string>
<string>FontAwesome5Solid.otf</string>
</array>
In my App.xaml I use this:
<OnPlatform x:Key="FontAwesomeBrands" x:TypeArguments="x:String">
<On Platform="Android" Value="FontAwesome5Brands.otf#Regular" />
<On Platform="iOS" Value="FontAwesome5Brands-Regular" />
<On Platform="macOS" Value="FontAwesome5Brands-Regular" />
</OnPlatform>
<OnPlatform x:Key="FontAwesomeSolid" x:TypeArguments="x:String">
<On Platform="Android" Value="FontAwesome5Solid.otf#Regular" />
<On Platform="iOS" Value="FontAwesome5Free-Solid" />
<On Platform="macOS" Value="FontAwesome5Free-Solid" />
</OnPlatform>
<OnPlatform x:Key="FontAwesomeRegular" x:TypeArguments="x:String">
<On Platform="Android" Value="FontAwesome5Regular.otf#Regular" />
<On Platform="iOS" Value="FontAwesome5Free-Regular" />
<On Platform="macOS" Value="FontAwesome5Free-Regular" />
</OnPlatform>
Could it be that the FontFamlily names other on macOS?
I checked that the font is in Resource folder in the macOS project and it is defined as BundleResource.
Thanks and greets,
Johann

I am trying to add a background image for my tabbed page. But I am not able to set it somehow.
And even I want to change the background color of the tabbed page bar.
code-behind:
viewModel = new UserRoomsViewModel(App.LoggedInUserId);
foreach (Room roomEntity in viewModel.roomDataStore)
{
Children.Add(new MyDevices(roomEntity.RoomId, roomEntity.RoomName)
{
Title = roomEntity.RoomName
});
}
I'm facing issue in Collectionview after implementing as staggeredgridlayoutmanager as given below"
Java.Lang.ArrayIndexOutOfBoundsException: 'length=4; index=36'
Note: "index=36" in the error may vary depending upon scroll position and "length=4" in the error statement i think are the number of visible items at any time in collectionview.
My Assumptions:
I think the error mentioned above always occurs when i reach to the end of collectionview and collectionview try to load more items. This is only happens when i fastely scroll collectionview and if i scroll normally then all is working well.
As for as i know, the think that is causing the problem is the layout measuring process after adding more items to the collectionview at reaching to the bottom of it and in that duration if i continue to scroll while collectionview is busy to measure the layout, then it will throw an exception as mentioned above.
And i think if i'm able to detect layout measuring process and stop further user scroll at that time, then i can solve the problem but the question is that is there anything exposed by collectionview or even at platform specific level (In my case android) to know that Layout Measuring processed is being performed
If i'm wrong, please someone can give me solution to solve that problem!

Hi everyone
I am developing an application with Xamarin Forms 4.3.0.9. I also use Shell in my project. My goal is to swipe between Tabbars. I've written custom renderer code for this. However, when used with shell structure, black screen error occurs on iOS side.
That's why I came up with the CubeView of the cardViews plugin I used in my project. Because the tabbar feature and you can scroll. But I have a problem.
With MVVM, I need to bind 4 of my pages into the card. I tried something for it, but I didn't get the result I wanted. I'm going to show you the codes I wrote down below. I ask you to tell me how to bind the page dynamically into the card with MVVM.
CardsSampleViewModel .cs
namespace GulaylarMenuDesign.ViewModel
{
public sealed class CardsSampleViewModel : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
private int _currentIndex;
private int _pageCount = 0;
public CardsSampleViewModel()
{
Items = new ObservableCollection<object>
{
new { Source = "DDD", Ind = _pageCount++, Color = Color.Red, Title = "Altın"},
new { Source = "DDD", Ind = _pageCount++, Color = Color.Red, Title = "Pırlanta", },
};
PanPositionChangedCommand = new Command(v =>
{
if (IsAutoAnimationRunning || IsUserInteractionRunning)
{
return;
}
var index = CurrentIndex + (bool.Parse(v.ToString()) ? 1 : -1);
if (index < 0 || index >= Items.Count)
{
return;
}
CurrentIndex = index;
});
RemoveCurrentItemCommand = new Command(() =>
{
if (!Items.Any())
{
return;
}
Items.RemoveAt(CurrentIndex.ToCyclicalIndex(Items.Count));
});
GoToLastCommand = new Command(() =>
{
CurrentIndex = Items.Count - 1;
});
}
public ICommand PanPositionChangedCommand { get; }
public ICommand RemoveCurrentItemCommand { get; }
public ICommand GoToLastCommand { get; }
public int CurrentIndex
{
get => _currentIndex;
set
{
_currentIndex = value;
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(CurrentIndex)));
}
}
public bool IsAutoAnimationRunning { get; set; }
public bool IsUserInteractionRunning { get; set; }
public ObservableCollection<object> Items { get; }
private object AddPage()
{
ContentPage page = new ContentPage();
var source = page.Content.BindingContext = "AltinPage";
return source;
}
}
}
Is there a way to bind the page into the DataTemplate in the following code?

Hi,
I am developing an application which contains Microsoft outlook and calendar.
Can anyone help me how to integrate Microsoft Graph Notifications in Xamarin.Forms
i am using Xamarin form,
Post is working using my Xamarin app to Sql server database using Asp.net Api,
but Get is not working to try to log in method.
my code is below.
using Seagullapi.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using System.Web.UI.WebControls;
namespace Seagullapi.Controllers
{
public class LoginController : ApiController
{
LoginEntities db = new LoginEntities();
// GET: api/Login
[HttpPost]
[ActionName("XAMARIN_REG")]
public HttpResponseMessage Xamarin_reg(login log)
{
try
{
login llogin = new login();
llogin.phone = log.phone;
llogin.password = log.password;
llogin.email = log.email;
llogin.first_name = log.first_name;
llogin.last_name = log.last_name;
llogin.dateofbirth = log.dateofbirth;
llogin.address = log.address;
llogin.city = log.city;
llogin.state = log.state;

llogin.passwordconfirm = log.passwordconfirm;
db.logins.Add(llogin);
db.SaveChanges();
return Request.CreateResponse(HttpStatusCode.Accepted, "Successfully Created");
}
catch (Exception ex)
{
return Request.CreateResponse(HttpStatusCode.ExpectationFailed, ex.ToString());
}
}
[HttpGet]
[ActionName("XAMARIN_Login")]
// GET: api/Login/5
public HttpResponseMessage Xamarin_Login(string phone, string password)
{
var user = db.logins.Where(x => x.phone == phone && x.password == password).FirstOrDefault();
