I'm really new to Xamarin and Xamarin forms and I need some help.
I have a StackLayout to which I want to add items dynamically from my ViewModel. Problem is I can't seem to bind the content of the StackLayout to my ViewModel's StackLayout.
this is my xaml code in my view
<StackLayout/>
I want something like
<StackLayout Content="{Binding MainStackLayout}"/>
I have a StackLayout already setup in my ViewModel like this
public StackLayout MainStackLayout;
I have a Xamarin Forms bottom placed tabbed page rendered using C#. I want a tab indicator to be displayed above each tab icons as it would in a top placed tabbed page. Is it possible? I am not able to find solution anywhere. I came across this SO post - https://stackoverflow.com/a/41570159/10329199, where we can define app:tabIndicatorColor="#123456" in Tabbar.axml. But I didnt work because I'm rendering the tabbar using C# not in AXML. I also want this tab indicator in iOS. Thanks
Our mobile app heavily depends on continuous syncing between app and server. For this we run multiple api's in the background(parallely) to fetch the data (like Account, Acc related items etc).
Every 5 mins sync process starts and it instantiates 12 api's. I have a backgroundtask(where I', handling httpclient methods) where all the 12 api's calls this task to fetch it's respective data.
public BackgroundTask(string authToken)
{
client = new HttpClient();
client.DefaultRequestHeaders.Add("Accept", "application/json");
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", authToken);
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", authToken);
}
api call:
private async TTask PostReturnMultipleAsync(string api, object postContent, CancellationToken cancellationToken)
{
try
{
var serializedContent = JsonConvert.SerializeObject(postContent);
HttpContent httpContent = new StringContent(serializedContent, Encoding.UTF8, "application/json");
response = await client.PostAsync(Constants.BaseUrl + "/" + api, httpContent, cancellationToken);
}catch(Exception ex){}
}
The issue is sometimes I'm getting strange errors in some sync process related to network. Let's say sync process starts at 12:00 pm I will be getting errors in some api's and another sync process starts at 12:10 pm, then it works fine.
The errors details are as follows:

I tried setting timeout to 50 seconds, that doesn't helps too. Any better to do this?
I've tried and tried but can't get this to work. Maybe it's not possible. I would like to load a css file per platform. Here's what I've tried.
<?xml version="1.0" encoding="utf-8" ?>
<Application
xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="eTabber.App">
<Application.Resources>
<StyleSheet Source="/css/Main.css" />
<StyleSheet Source="{OnPlatform iOS=/css/iOS.css, Android=/css/Android.css}" />
</Application.Resources>
</Application>
ERROR: Source is not a String Literal
and this:
<?xml version="1.0" encoding="utf-8" ?>
<Application
xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="eTabber.App">
<Application.Resources>
<StyleSheet Source="/css/Main.css" />
<StyleSheet Source="/css/Dummy.css" >
<StyleSheetExtension.Source>
<OnPlatform x:TypeArguments="x:Uri">
<On Platform="Android">/css/Android.css</On>
<On Platform="iOS">/css/iOS.css</On>
</OnPlatform>
</StyleSheetExtension.Source>
</StyleSheet>
</Application.Resources>
</Application>
This compiles but does nothing at all (Ok, it does load the dummy.css). If I leave out the 'Dummy.css' it complains it needs a 'Source'.
I also tried loading it in code behind. That works but then 'Hot XAML reloading' is not working.
B.t.w: compilation of this stuff is just instable. I had to delete 'bin' and 'obj' on several occasions and also had to restart VS2019.
I am using MVVM Prism for the Xamarin mobile app.
I created a NetCore 3.1 rest api that serves as the backend to my Xamarin mobile app. I want to be able to debug it locally.
I would like to:
A. Connect to localhost to debug the rest api from the Simulators
B. Also would like to connect to the localhost kestrel from the mobile app itself in debug mode if possible
I am using NetCore Kestrel instead of IIS to host the rest api in the localhost.
I can connect with Postman locally and DEBUG ok in VS using this URL:
even though I do get a first certificate validation error, but I turned off Certificate validation in POSTMAN to make it work, but when I try to connect to that same URL from the mobile, with the code below I get this error:
I have been struggling with this for 2 full days, this is my code:

It is possible that this question does not correspond to ask it but I would like to ask you if there is any alternative way to test the controls on iOS without having a MAC computer
It would help me a lot

Hi All,
I am having a ContentView where i add DataTemplate as its content. Is there any way to measure the size of the content view based on its content. Please note that its content can be any view. I can measure the size of the content if the height and width are explicitly set when defining the DataTemplate like in the below case.
<DataTemplate> <Entry x:Name="numeric" Text="{Binding FirstName}" FontSize="12" TextColor="Black" WidthRequest=150 HeightRequest=100 Keyboard="Numeric" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" /> </DataTemplate>
But when the height and width are not specified , the measure call returns -1 as width and height which is the behavior of the framework, since the measure call fetches the size only from the WidthRequest and HeightRequest properties. Is there any way to overcome this and get the actual size of the view based on the content.
Awaiting your suggestions. Thanks in advance !

I have a fairly complicated hierarchy of controls, going from a ScrollView to a ListView, to a StackLayout with a combination of buttons and a slider. If a user scrolls the page, they can start the swipe from most anywhere, including on top of a button, and the page will scroll without triggering any UI control events. However, if they try to scroll and accidentally start swiping up or down from on top of a slider, the slider moves instead of the page scrolling.
Is there any reason this is different from the way the buttons work? Is it possible to wait until the gesture is confirmed to be horizontal before allowing the slider to activate? It's frustrating to users when they are just trying to scroll through the page but accidentally change a slider value. I can change the workflow a bit to require confirmation of a slider change, or unlock the slider first somehow, but it'd be nice to keep things simple like they are.

Hi,
My Xamarin Forms iOS app is running perfectly on an emulator but crashing after splash screen on an iPhone device. I tried all the accepted from Xamarin Forums and StackOverflow. Nothing seems working.
I put try-catch blocks on Main.cs, AppDelegate.cs under the Xamarin Forms iOS app and under App.xaml.cs in the Xamarin Forms, it is not even triggering my try-catch blocks, even before the app crashes.
This occurs only on the real device [iPhone 6s iOS 13.3]
