Hello,
I have the next example:
<StackLayout Padding="16" Spacing="16">
<Label Text="{Binding Title}" FontAttributes="Bold" />
<BoxView Color="Gray" HeightRequest="1" />
<Label Text="{Binding SubTitle}">
</StackLayout>
Like can I do so that it does not affect padding BoxView?

Sorry if the question's a bit convoluted! This has me stumped at the moment: I have a ListView and I'm creating the DataTemplate programatically to be able to make it responsive. My ListView's ItemSource is a list called "Recipes" made up of "Recipe" objects.
How can I create a label in codebehind and bind its text property to, say, Recipe.Title? Here's my current code and what I'd like it to do:
private void GenerateTitleLabel(Grid grid)
{
Grid.SetColumn(grid, 1);
grid.Margin = 1;
grid.RowDefinitions.Add(new RowDefinition { Height = new GridLength(2, GridUnitType.Star) });
grid.RowDefinitions.Add(new RowDefinition { Height = new GridLength(4, GridUnitType.Star) });
grid.RowDefinitions.Add(new RowDefinition { Height = new GridLength(2, GridUnitType.Star) });
grid.RowDefinitions.Add(new RowDefinition { Height = new GridLength(2, GridUnitType.Star) });
Label title = new Label
{
Style = Application.Current.Resources["styleLabelTitle"] as Style,
};
//Here I'd set the binding to the Title attribute in my Recipe class
title.SetBinding(???);
Grid.SetRow(title, 1);
}
That's it. If anything's unclear, let me know!
Hey guys,
I'm really frustrated and require some help from you. I'm not really new at Xamarin, but some things won't get in my brain. Maybe I haven't understood the entire logic so far.
But, my problem is: I've been adding a Button to the content page and all were working fine. So, I had to change the background color and now it's messed up! When I click the button, it shows WHILE the press event is invoked, a small visible rectangle with the 0.25 scale of the entire button on the top left of the button.
Can someone help me? I've made a screenshot WHILE PRESSING THE BUTTON here:
Note: BEFORE changing the background color, all has been working fine. AFTER setting the background color, the color gets changed well and is correct but the PRESS/CLICK/ACTIVE state of the button shows a small - unrequired - rectangle on the top left of the button.
Thankful for every answer.
Kind regards,
Dominik G.

Hi All,
I'm having an issue with httpClient, but only on my iOS device (I've not checked Android but I'm not targeting it), it works well in the emulator.
When my app loads the ViewModels do a API call to try and get data from my server and I almost immediately get a System.Net.WebException: Error: NameResolutionFailure crash. I don't get this in the iOS emulator for the same API call.
I tried calling https://jsonplaceholder.typicode.com/posts which I know works and rules out anything idiosyncratic bugs in my code but it still fails.
Is there anything special I need to do enable internet access on an iOS device? Could I have set up something wrong in my provisioning profile in the Apple Account?
Thanks in advance

I added mapview using xamarin.forms.maps package. I wanted to add a searchbar field to search address and drop pin using search box.
How to add a SearchBar programmatically a search a location?
I tried the following:
var searchField = new SearchBar
{
Placeholder = "Enter search term"
};
searchField.SearchCommand = new Command(() => { if (searchField != null) { string.Format("Result: {0} is what you asked for.", searchField.Text); }
** // I don't get the text here**
Content = new StackLayout
{
Spacing = 0,
Children = {
searchField,
map,
buttons
}
};
I have the following XAML:
<ffimg:CachedImage HeightRequest="400" WidthRequest="400" Source="{Binding ImageUrl}">
<fffimg::CachedImage.Transformations>
<fftransformations:CircleTransformation/>
</ffimg::CachedImage.Transformations>
</ffimg::CachedImage>
I would like to set the <fftransformations:CircleTransformation/> only if : {Binding IsRoundImage}. Is it possible to do this directly in XAML? I have tried DataTriggers but it doesn't work.
This is for tracking incoming and outgoing phone calls. I am pushing a Xamarin form in the application Navigation stack from BroadcastReciever class using following code:
var phoneAddPage = new SomePage();
Xamarin.Forms.Application.Current.MainPage = new NavigationPage(phoneAddPage);
The page is getting pushed properly as expected. Issue is the page is overlapped by Splash Screen when application is opened. The form is functioning properly, overlap is the only issue.
