I'm trying to solve some problems with two Master-Detail tabs. So my question, why are the ToolbarItems (Cancel/Save) twice on the page?

I have multiple Classes which inheritance from BaseTestFixture class.
each class has multiple tests which are shared the same preconditions
I want at the beginning before proceeding to generate randomly two emails one for registration test and the other I want to sign in using it using backdoors. where can I Put this logic to execute only once for each device?
And If I want to execute Precondition for a class only once not before each test in that class where can I do that?

Sorry to bother you, but I've come across a error in my code I don't how to deal with.

Whenever I try to run my app, I get faced with this:

System.TypeLoadException: 'Could not resolve type with token 01000019 from typeref (expected class 'Xamarin.Forms.Xaml.Diagnostics.VisualDiagnostics' in assembly 'Xamarin.Forms.Core, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null')'

It states it occurs when the InitializeComponent(); is called in the constructor of App.xaml.cs.

Constructor in question:

public App()
    {
        //Line throwing the error
        InitializeComponent();

        MainPage = new NavigationPage(new Login.LogonFinal()); 
    }

App.xaml.cs

using System;
using Xamarin.Forms;
using Xamarin.Forms.Xaml;

namespace NEA_I_MDL
{
    public partial class App : Application
    {

        static Databases.AccountDatabaseController AccountDatabaseVar;

        public App()
        {
            //Line throwing the error
            InitializeComponent();

            MainPage = new NavigationPage(new Login.LogonFinal()); //Defines what page the app opens on when starting
        }

        protected override void OnStart()
        {
            // Handle when your app starts
        }

        protected override void OnSleep()
        {
            // Handle when your app sleeps
        }

        protected override void OnResume()
        {
            // Handle when your app resumes
        }

        public static Databases.AccountDatabaseController AccountDatabaseFunc
        {

            get
            {

                if(AccountDatabaseVar == null)
                {
                    AccountDatabaseVar = new Databases.AccountDatabaseController();
                }

                return AccountDatabaseVar;

            }

        }

    }
}

Thank you for reading, any tips/assistance will be a huge help for my ineptly written code.

We've been trying SignalR on our mobile apps (Droid & iOS) in order to receive info on a stream and not worry about timers and collapsing the API.

Unfortunately, the time between connection and receiving the info we need to show is very inconsistent. Sometimes is just mere seconds, but most of the time takes longer than 10 minutes or so, and it's really frustrating.

Here are some code samples we've use, some parts have been, erm, altered because we cannot share our code online (at least the part that connects to our private data servers and such):

Here is where the hub connection is initialized.

SERVERLOC: is the url where the server is located
URLDATA: where we connect to get the data needed
HEADERNAME & HEADERDATA: a header is needed since, depending on different configurations, shows various data.

HubConnection connection = new HubConnectionBuilder ().WithUrl (/*"SERVERLOC", /*/"URLDATA", HttpTransportType.LongPolling, options => { options.Headers["HEADERNAME"] = "HEADERDATA"; }).WithAutomaticReconnect(new[] { TimeSpan.FromSeconds(30), TimeSpan.FromMinutes(1), TimeSpan.FromMinutes (2) }).Build ();

METHODNAME: Here, since it's basically an api, with the parameters sent within the header, we will tell the server which method we want to consult in order to get the desired data (for instance, a list of strings)
`try {
connection.On<List> ("METHODNAME", param => {
Console.WriteLine (param);
});

                if (connection.State == HubConnectionState.Disconnected) {
                    await connection.StartAsync ();
                    await DisplayAlert ("Warning", "Connecting. Please, wait", "OK");
                }

                connection.Closed += (error) => {
                    DisplayAlert ("Error", "Connection lost. Please, try again", "OK");
                    return Task.CompletedTask;
                };
            } catch (Exception ex) {
                Console.WriteLine (ex.Message);
                SetHorariosVisible (false);
            }`

Before finishing, I will add the 'Microsoft.AspNetCore.SignalR.Client' package version, for others to try (3.1.1).

If there is any info you need and we're missing, please tell us.

I can already load and display SVG but only by using blend mode to apply a uniform color

I have images which contain paths which need different colors to be applied

Please can someone demonstrate to me how I reference each and determine what color is appropriate?

what's the road to having a widget included in my xamarin.forms installation package?

Hi everybody.

I'm building a search - function in Xamarin (see code below):
I'm filling a Listview with data ( public async void FillSearchList()).
When the user writes in the entry, the datalines,
which content corresponds to the search-text,
are shown in the listview (through private void SearchList_OnTextChanged(object sender, TextChangedEventArgs e)).
The user picks a data-line ((private void SearchList_OnTextChanged(object sender, TextChangedEventArgs e))),
and this is being shown in the entry.
The problem is as follows:
First time the user picks a data-line, there are no problems. However, when picking a dataline for the second time,
the program freezes, Visual Studio 2019 freezes, and after a while the message below (in the picture) appears.

I searched for the error for a long time, but sadly -> no luck. In VS 2019 I tried to "Empty symbol cache" and chose "Microsoft Symbol Servers"
under Debug->Options->Debugging->Symbols (picture 2 below). It did not help.

Does anybody have an idea, how to fix this?
Friendly regards

Hello All, I am relative new to Xamarin. I have started building a Shell Application.
From one of my tabs I have a button where I navigate to another page which is fired form a command in my ViewModel
This is the code to navigate to the page - await Shell.Current.Navigation.PushModalAsync(new AddNewItemView(), false);

1. How do I get a busy spinner to show while loading the new page? I am using Syncfusion controls but I have yet to find a way for the spinner to show. I have tried all there examples but its not working.

2. PushModalAsync seems to be VERY VERY slow. If I go to "PushAsync" it speeds up to a fraction of the time. I am not sure why. It all seems rather clunky, however it could me from my lack of understanding.

I have updated Xamarin.Forms to 4.5.0.617 and Xamarin.iOS to 13.0.16 in my visual studio
I am using grep -r UIWebView .(dot) command to check for references which, as an output shows references in files listed below,

Xamarin.Forms.Platform.iOS.dll
Xamarin.iOS.dll
Xamarin.iOS.pdb

and

./.vs/[ProjectName]/xs/sqlite3/storage.ide

Can someone please help me with this?

I want to share an url, the url of page where I am, to my Xamarin Forms App (Android and iOS).

And when I',m going to share this url...

I want that my app appears into the share options list, to send this url to my app to a specific page, beacause I want to use this url strings into the app.

I know there are many ways to prevent multiple clicks on a button in Xamarin, but is there a single solution to prevent it globally? i.e. in every button in my app. Otherwise, what would be the best solution for me to do it to every button I have?

Doubles have imprecisions which can cause odd things to happen in your app. For instance this code:

        double a1 = 1;

        double c1 = UnitConverters.CelsiusToFahrenheit(a1);
        double c2 = UnitConverters.FahrenheitToCelsius(c1);

        if(c2 == a1)
        {
            // will never get here
        }

// c2 equals something like .999999998 and a1 equals 1

These methods should be overloaded to be able to take decimals and return decimals.

Hello everybody! I have a little question about using a ControlTemplate in XAML. Let me explain what my trouble is. I have the fresh installation of VS 2015 with Xamarin. I had created new cross-platform solution (Xamarin.Forms v 2.0.0.0) with PCL. Then, I had added new XAML Page and within it I had created simple control template with one label (in resources of the page). Below I had created ContentView with property ControlTemplate binded to that resource. But when I try to compile I receive the error "The Type 'ControlTemplate ' not found in namespace 'http://xamarin.com/schemas/2014/forms'". And it's odd because at this page 'https://developer.xamarin.com/api/type/Xamarin.Forms.ControlTemplate/' we can see that ControlTemplate exists in this assembly and should be reachable. If I update Xamarin.Forms the problem is disappear and everything works but then i can't compile iOS app because my Xamarin Studio on my mac has different version of the library. Does anybody know how I can solve my problem? Thanks

P.S. Sorry for my English

Hi everyone,
I have simple problem but i could not solve it.
I know how i can use multilingual plugin and how i can do databinding. But how do i can use them together?
I have a lot of situation for a label. Let me explain:

{Binding Status}
Status = "Status: No internet connection"; ---------> Translator key => NOINTERNETCONNECTION
Status = "Status: Did not found any files."; ---------> Translator key => NOTHINGFOUND
(......)

I want to use them like that and translate.
{translator:Translate {Binding Status}} ----------> {translator:Translate NOTHINGFOUND} ----------> "Dosya bulunamadı."

Yes, it doesnt work. But, you know, i tried my chance. (It looks like chaos, i know)

I hope I was able to express myself.

STAYHOME and... #HELPME

Does anybody know what this is called when a notification does this "quick display" thing at the top of the device for 1-2 seconds before going away and just having the icon in the notification tray? Is this a setting that has to be specified when building out the notification using NotificationCompat.Builder? Is it a setting elsewhere?

Here is where I took the screenshot. You can see the full GIF in action from the point of the user clicking the button to send the notification, the notification being received, the "quick display" thing that I'm asking about, and then the notification disappearing into the tray.

I've been trying to get my own Xamarin.Forms application to do it but instead when I get a notification it immediately goes to showing the tray icon and that's it.

Hi,

When I create new Xamarin.Forms project for Android (from some template) it works fine. But when I switch to armeabi-v7 arcitecture only it will show only white screen on my phone (testing on Galaxy S10). Build and deployment throws no error or warning, debugger can not be attached.
What am I missing ?

Thanks

Since I upgraded, two days ago, to the latest version of Visual Studio for Mac the XAML previewer no longer renders for iOS (Android still works), This is the stack trace it renders instead:
