Hello,
I'd like to do something like shown in the attached picture. Do you guys have any suggestions on how I should go about doing it, do I need to write my own control? The drop down and the search bar can be separate components, I just want a dropdown-list to pop.
Hi,
I have a Button with an Image inside, but my users think that a picture with text would be better. The problem is, when the resolution is not too big, text and image takes too much place. A better solution is, when the display/resolution is big enough, show the picture with text otherwise the image only. I took a look into the VisualStateManager stuff, but do not know how I to trigger the different states by changing the resolution. This XAML style I place into the button style:
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="ShowTextStates">
<VisualState x:Name="ShowText">
<VisualState.Setters>
<Setter Property="Text" Value="Test test test..." />
</VisualState.Setters>
</VisualState>
<VisualState x:Name="HideText">
<VisualState.Setters>
<Setter Property="Text" Value="" />
</VisualState.Setters>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
How can I solve this problem? Any suggestions? Thank you!
I need implementation similar to highlighting the text inside the paragraph on selecting the particular text.
Hi all
I want to introduce a nuget package which allows reloading XAML views from Visual Studio on your running app.
This package works for Mac too!

Hi everyone!!
I have a big issue that I can't solve from myself.
like the title says, in my android app (using xamarin.forms 3.4.0.1009999 after I updated from a very old version) when I select an entry, then tap over a picker, it opens twice.
A workaround I found is to place the picker in a StackLayout.. but when the picker is in a grid this workaround doesn't work.
Searching into the web, this issue should be resolved in release 3.4.0.1 so.. any ideas?
thanks!!!

Is there a way to speed up the performance of ListView, which uses over 200 Bindings?
This is a list that uses mostly Label elements, I do not use images at all.
Good day
I am using Firebase Messaging to send/Receive Push Notification on Android.
I've got the following implementation which is triggering OnMessageReceived twice on Android v 8.0, after rebooting the phone once, opening the app, rebooting the phone again and then sending myself a push notification.
Any ideas on what is causing this? I've looked online and found suggestions on removing any old GCM references which I have done already. The first time the app is built and deployed to the device, it doesn't happen and all subsequent push notifications seem fine. This just happens when the phone goes through the above mentioned reboot procedure. It may happen in other cases too but this has been my method to re-create the issue.
The App is compiled using

Hi, I've tried to use three different fonts on Xamarin.Forms and on Android works fine, but on iOS it doesn't work...
I followed this example: https://developer.xamarin.com/guides/xamarin-forms/user-interface/text/fonts/

2. I edited Info.plist file and now i have:
3. I'm trying to use like this:
<Label.FontFamily>
<OnPlatform x:TypeArguments="x:String">
<On Platform="iOS" Value="Black" />
<On Platform="Android" Value="Black.ttf#Black" />

Hi there! I'm facing the following issue:
I have a drawer menu (implemented with MasterDetailPage) with 3 items. When you first run the app you see an hamburger menu icon on top left.
When you click in one of these items, the page loads with an back arrow.
I'm trying to accomplish that these three pages must still have the hamburger menu item on its Action Bar. And the navigation after those, loads with the back button.
I ended up thinking that the Icon property for MasterPage won't work for Android.
I made it work on iOS but nothing I do seems to work on Android.
My code:
MainPage.cs
public class MainPage : MasterDetailPage { protected override void OnAppearing() { base.OnAppearing(); this.GetMenuPage().ListView.ItemSelected += OnItemSelected; } private void OnItemSelected(object sender, SelectedItemChangedEventArgs e) { var item = e.SelectedItem as Menu; if (item == null) return; // this.GetNavigationPage().PushAsync((Page)Activator.CreateInstance(item.Pagina)); ((NavigationPage)this.Detail).PushAsync((Page)Activator.CreateInstance(item.Pagina)); this.GetMenuPage().ListView.SelectedItem = null; IsPresented = false; } }
MenuPage.xaml
<?xml version="1.0" encoding="utf-8" ?> <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="BNB.CapturaGeodesica.MenuPage" Padding="0,40,0,0" BackgroundColor ="#A5183C" Title="Menu " Icon="ic_hamburguer_menu"> <!-- ## This works on iOS. But on Android, it won't show up. ##-->
DetailPage1.cs
public DetailPage1() { NavigationPage.SetHasBackButton(this, false); // Here I get rid of the back button. But I can't manage to show the menu icon on Android. InitializeComponent(); }
I'm attaching the result on iOS and Android. Just to clarify, to reach "Second page" on iOS or Android, assume that I opened the drawer menu and selected "Second page".
OBS: I need to have the page history.
Thank you for any help!
I have developed app for ios and android in xamarin form cross platform. The problem i am facing in notification that i can recive notification in android and its working absolutely fine, even i can open specific page from notification data, but in IOS i am not able to recieve notification.

Hello All,
I am beginner in Xamarin and trying to consume REST API in Xamarin forms to display the data using ListView in tab page. Below is the Xamarin version in my development environment:
Xamarin - 4.12.3.78
Xamarin.Android.SDK - 9.1.5.0
VS 2017 - Community (15.9.5)
The problem is,
For Android, let's say if we run the application 10 times, it gets the response from REST API 5-6 times only. In other case, the application gets stuck at 'HttpResponseMessage response = await client.GetAsync(subUrl)'.
I don't understand what is the error? Is there any way we can see the log for this error?
Also, even for UWP, the application is throwing an error "Access Denied".
I have attached the screenshots of the Xaml and Xaml.cs file for the reference.
Can anyone please help me on this?
I have a basic ListView that uses a DataTemplateSelector
<ListView **x:Name="listView"** ItemsSource="{Binding PostDb}"
ItemSelected="ListView_OnItemSelected"
ItemTemplate="{StaticResource ActivityDataTemplateSelector}"
HasUnevenRows="True"
IsPullToRefreshEnabled="true" Refreshing="ListView_OnRefreshing"
SeparatorVisibility="Default"
SeparatorColor="Gray" />
But I have simply no idea how to retrieve listview's reference inside my DataTemplates.
<Image Source="Test.png">
<Image.GestureRecognizers>
<TapGestureRecognizer
NumberOfTapsRequired="1"
BindingContext="**{Binding Source={x:Reference listView}**, Path=BindingContext}"
Command="{Binding CommentButton}"
CommandParameter="{Binding Source={x:Reference LayoutButtons}, Path=BindingContext}"
/>
</Image.GestureRecognizers>

Any guess?
Hi.
I have a XAML form with button.
<StackLayout.BindingContext>
<viewModels:CartVM/>
</StackLayout.BindingContext>
<!-- other code -->
<ListViewItemsSource="{Binding Items}">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
Button Text=" - "
Command="{Binding DecreaseQtyCommand}"
CommandParameter="{Binding}"
/>
<!-- other code -->
This is the ViewModel:
public class CartVM : BaseViewModel
{
public CartVM()
{
Items.CollectionChanged += ItemsHasBeenChanged;
}
public ObservableCollection<ShopCart> Items
{
get
{
return // list
}
}
public string Title {get;set;}
public string TotalAmount{get;set;}
public ICommand DecreaseQtyCommand
{
get
{
return new Command<ShopCart>((ShopCart shopCart) =>
{
shopCart.Qty -= 1;
OnPropertyChanged("Items");
});
}
}
The prolbem only with the Commands, the other Properties of CartVM work via Binding on the Xaml, like CartVM.Title, CartVM.TotalAmount

I want to know when a button is pressed and when a button is released. I seen this example where the gestures are captured for a label here:

Hello dear Xamariners !
I'm wasting a lot of time trying to figure out why FontAwesome doesn't work on Android & iOS.
No need to tell you that I've tried several solutions I found on this forum.
To help you to help me (what ? haha)
Here are some screenshots :
On iOS :
On UWP or Android (kind of same result I don't have the right icon)
The FontFamily resource in app.xaml :
My Fonts folder :
My VS fonts Android folder with the properties AndroidAsset // copy if newer
My VS fonts UWP folder with the properties Content // Do not copy
Do you have any idea why it isn't working ?
I've tried several way to declare my font (without the otf.#name of font , with .otf#name of font style , with .otf only)
If anybody got this working, it would be awesome 
to get some help.
PS : I'd like to avoid a custom renderer
I wish you all a good weekend !
