Description Tyler_hartwig 2015-06-04 00:26:42 UTC
When writing a Xamarin.Forms app using XAML and Styles, the Padding property of a style is not applied for Frame views.  I have attempted this on both iOS and Android, and neither apply this particular style property.  Here is the XAML code I created, it is also in the attached project.  

<?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="FormsFrameBug.FramesPage">
			<Style TargetType="Frame">
				<Setter Property="Padding" Value="0" />
				<Setter Property="VerticalOptions" Value="CenterAndExpand" />
			<Style TargetType="Frame" x:Key="ExplicitStyle">
				<Setter Property="Padding" Value="0" />
				<Setter Property="VerticalOptions" Value="CenterAndExpand" />
			<Frame BackgroundColor="Blue">
				<BoxView BackgroundColor="Red" />
			<Frame Style="{StaticResource ExplicitStyle}" BackgroundColor="Yellow">
				<BoxView BackgroundColor="Red" />
			<Frame BackgroundColor="Lime" Padding="0">
				<BoxView BackgroundColor="Red" />

I believe each of the Frame Views in this stack layout should be rendered identically, as each of their padding properties should be 0.  The sample also displays that the issue occurs with both implicit and explicit styles.

I also failed to mention that I have experienced this both in a PCL Project and a Shared Project, in case that is relevant

A user in the forum ran into this issue (http://forums.xamarin.com/discussion/51824/frame-padding-can-it-still-be-changed). I can confirm that it is still present in 1.5.0.

I have this issue as well. This shouldn't be too difficult to fix. Not sure why it's been months without progress.
Comment 5 Jason Smith [MSFT] 2016-04-09 01:28:24 UTC
Because it presents a backwards compat issue and a proper fix requires work into the binding system :/

It's still on our list.

>and a proper fix requires

Then do *unproper* fix. Seriously you are adding new features every major release and can't fix this that kind of annoying bugs.
Comment 7 n.podbielski 2016-04-22 12:19:15 UTC
Here is @Jason quick fix for you (add this method to Frame class and you done):

protected override void OnPropertyChanged(string propertyName = null)
            if (propertyName == StyleProperty.PropertyName)
                if (Style.Setters.Any(s => s.Property == PaddingProperty))
                    Padding = (Thickness)Style.Setters.First(s => s.Property == PaddingProperty).Value;

I can reproduce this in 

Tested on:

iOS 10.3 Simulator, 
iPhone 6S iOS 9.3.5

Applying Padding via Style does not work.
