Some of the pages in my Xamarin app are tabbed pages - navigation between these pages (using the tabs) works perfectly.

However, some of my pages are not accessible via the tabs, for example, I am displaying a list of items, and clicking on one of the items take you to a detail page for the list item that was clicked. This is handled in the cs code behind for the list page, and navigation is triggered using this:

await Navigation.PushAsync(new DetailPage(DetailPageViewModel)); 

This works, in that it does take you to the detail page, but the page is cut off, and only the lower part of the detail page can be seen - the top half of the page is not displayed and cannot be scrolled to. It only seems to be a problem with iOS, Android does not show the same issue.

Is this a known bug, or am I doing something wrong?

I am trying to make a label wrap inside of the Master page of a MasterDetail page. I thought it was the default behavior to wrap labels, but just in case I even made a custom renderer. I have confirmed that the custom renderer works (through debugging and adding a background to the label), so I assume there is something easy that I am missing. Can anybody take a look at my xaml and give me an idea why this label is not wrapping?

And my (most likely unnecessary) custom label renderer:

using MyApp.iOS.Renderers;
using MyApp.Pages.NavigationDrawer;
using Xamarin.Forms;
using Xamarin.Forms.Platform.iOS;

[assembly: ExportRenderer(typeof(MultiLineLabel), typeof(MultiLineLabeliOSRenderer))]
namespace MyApp.iOS.Renderers
{
    public class MultiLineLabeliOSRenderer : LabelRenderer
    {
        protected override void OnElementChanged(ElementChangedEventArgs<Label> e)
        {
            base.OnElementChanged(e);

            if (Control == null) return;

            Control.LineBreakMode = UIKit.UILineBreakMode.WordWrap;
            Control.Lines = 0;            
        }
    }
}

I generated a new shell app in Visual Studio Community 2019, which gave me an App.Shell.xaml file containing some styling, like this:

<ResourceDictionary>
        <Style x:Key="ShellStyle" TargetType="Element">
            <Setter Property="Shell.TitleColor" Value="Fuchsia" />
            <Setter Property="Shell.BackgroundColor" Value="Green" />
            <Setter Property="Shell.ForegroundColor" Value="Yellow" />
            <Setter Property="Shell.TitleColor" Value="Red" />
            <Setter Property="Shell.DisabledColor" Value="#B4FFFFFF" />
            <Setter Property="Shell.UnselectedColor" Value="Grey" />
            <Setter Property="Shell.TabBarBackgroundColor" Value="Blue" />
            <Setter Property="Shell.TabBarForegroundColor" Value="Indigo" />
            <Setter Property="Shell.TabBarUnselectedColor" Value="Lime" />
            <Setter Property="Shell.TabBarTitleColor" Value="Teal" />
        </Style>
        <Style TargetType="ShellItem" BasedOn="{StaticResource ShellStyle}" />
    </ResourceDictionary>

Those weren't the default colours by the way...

Anyway, none of those styles were being applied to the shell items (the bar right at the top of the app, or the tab bar at the bottom. The title is displayed at the top, and the tabs at the bottom, they just didn't have the above styling.

I managed to fix the tab bar, by adding some new styles to the resource dictionary:

<Style x:Key="TabStyle" TargetType="TabBar">
    <Setter Property="Shell.TabBarBackgroundColor" Value="Teal" />
    <Setter Property="Shell.TabBarUnselectedColor" Value="Silver" />
    <Setter Property="Shell.TabBarTitleColor" Value="Fuchsia" />
</Style>

Then I just applied the style to the TabBar in the usual way:

<TabBar Style="{StaticResource TabStyle}">
    ...
</TabBar>

This works perfectly and the styling is applied to the tab bar at the bottom. Unfortunately, I cannot get any styling to work for the top bar of the app. None of the styles like Shell.TitleColor or Shell.BackgroundColor have any effect on the app whatsoever, and unlike with the TabBar, I don't have a <TitleBar> or any element to manually add styles to.

I did think about hiding the shell top bar, and using my own one instead, but I guess with this approach, I would then have to handle navigating back to previous pages.

What's the recommendation here? Why isn't the shell styling working as this page says it should: https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/shell/configuration#set-page-colors ??

Hello.

I need to develop an application for Datalogic Memor 1 device (Handheld device that has android oreo and 1d laser integrated barcode scanner.)

They have a tutorial to use SDK with Xamarin. datalogic.github.io/xamarin/quick-start/

But their sample is Xamarin.Android project, not Xamarin.Forms. Is it possible to use barcode scanning feature from Xamarin.Forms only ? How can i integrate that to Xamarin.Forms?

Is there any way to detect key events from a physical keyboard on UWP project?, or its posible to create a custom renderer and assign "onkeydown event" to it?

Hi,
I'm currently having a little problem understanding how OnIdiom works sometimes
In my Application Resources i have this :

            <x:Double x:Key="GlobalHeight">
                <OnIdiom x:TypeArguments="x:Double" Tablet="44" Phone="88"/>
            </x:Double>

But this doesn't work and it is rendered as if the size was null the problem is that it is working here

            <Setter Property="FontSize">
                <Setter.Value>
                    <OnIdiom x:TypeArguments="x:Double" Phone="12" Tablet="15"/>
                </Setter.Value>
            </Setter>

I'm calling it like this

<StackLayout HeightRequest="{StaticResource GlobalHeight}">

Is there a way to make OnIdiom work on a Double in a ResourceDictionary ?

Hello

I have a Xamarin Forms Shared Project which can build and deploy without errors. However, the following build warning have appeared:

There was a conflict between "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" and "mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e".

The build warning seems to have appeared after updating Visual Studio and I cannot get rid of it.
I have tried cleaning the project, removing bin folder, .vs folder and building a new project with the same dependencies but that does not replicate the warning.

I have found other posts with a similar issue to this but I do not know if those problems are related:

Hello,
I am currently building an application/library using Skiasharp which needs graphs. These graphs are updated each 4 ms with a new sample of data which is printed on the screen. I managed to make everything work but it is really slow.
1 second on my graph is actually 2 seconds in real life, it takes way longer than it should and I don't get why. I tried it with less frames and sample and I does everything fine up to 1 sample each 25 ms.

Does anyone know if this comes from Skiasharp because it can't refresh faster than 25ms ?
Does anyone know if there is a way to control the time Skiasharp takes to draw on the canvas ? To draw and update my graph I am using InvalidateSurface.

Thank you a lot for your help
Kind regards

Hi, How can i do the custom render for a collection view selected cell like did for a listview ?

Xamarin forms 3.4 (iOS)
I some cases the locale of the iOS is not valid for .net.
For example the locale returned from an iOS device can be en-BE or en-ES.
Because the returned locale (en-BE) is not valid in .net, I use a fallback which is en.
The problem is when an Entry control is bound to a decimal field and the Keyboard of the Entry is set to Numeric.
The soft keyboard that appears on the device has a comma , for decimal separator (coming for the BE part of the device culture) which is not valid for the fallback culture (en). As a result, the entry cannot accept decimals.
How can I solve this problem?

Hi,

I am using the following Xamarin Code

<ListView ItemsSource="{Binding UserGroups}" RowHeight="66">
          <ListView.ItemTemplate>
            <DataTemplate>
              <ViewCell>
                <StackLayout Orientation="Horizontal" Spacing="10" Padding="10,10,10,10" TranslationX="10">
                  <Label
                    Text="{Binding Name}"
                    VerticalOptions="CenterAndExpand"  >
                    <Label.GestureRecognizers>
                      <TapGestureRecognizer  NumberOfTapsRequired="2" Tapped="OnEditGroupClicked" CommandParameter="{Binding Name}" />
                    </Label.GestureRecognizers>
                  </Label>
                 </StackLayout>
              </ViewCell>
            </DataTemplate>
          </ListView.ItemTemplate>
    </ListView>

Tapped event is firing, but sender and args are getting as unknown identifier, I am not able to figure out the issue

On Code behind file,

async void OnEditGroupClicked(object sender, EventArgs args)
{
// I want to access the Name
}

and sender and args are getting as unknown identifier

Can someone guide me the correct way to pass the parameter to tapped event

Thanks in Advance

Hi,
I'm currently trying to build a Forms UI using the collection view but however I have a problem with the gesture recognizer using android. In iOS all works fine the the events fires when tapping the BorderView (inside the collection view template) but on andoird the events get never fired and I dont know why. I've tried to use the InputTrasnparent Property but that doesnt chnage anything at all.

Here is my xaml code:

                <CollectionView ItemsSource="{Binding Studies}"
                                ItemSizingStrategy="MeasureFirstItem"
                                HeightRequest="200">
                    <CollectionView.ItemsLayout>
                        <GridItemsLayout Orientation="Vertical"
                                         Span="2" />
                    </CollectionView.ItemsLayout>
                    <CollectionView.ItemTemplate>
                        <DataTemplate>
                            <StackLayout Padding="10,0">
                                <xe:BorderView HeightRequest="80"
                                               CornerRadius="10"
                                               WidthRequest="50"
