When implementing and the Hamburger Menu pane opens, the bottom part (Setting) is covered/hidden by the BottomAppBar.
Solution:
Simply add another grid row to your page and implement a CommandBar there:
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<... Grid.Row="0"/>
<... Grid.Row="1"/>
<CommandBar Grid.Row="2"/>
</Grid>
I am pleased to tell you that a Template 10 sample project demonstrating how to implement Bottom App Bar already exists and you can review it on GitHub.

I've got a mockup with a screen I don't know how to implement properly:
I'm wondering how to position that Login button (and the "sign in with" block). Without "Login", it would be quite easy with a StackLayout. But this makes it less easy and I'm searching for a simple solution.
I presume it's feasible with an AbsoluteLayout with position calculations in the codebehind, but that makes the whole page more complicated than it looks.
The white block is a Frame that's used everywhere in the app. It's not specific to the login page, so I want to reuse it elsewhere.
How would you do that?
I think you can use a Grid... with 3 rows.
Rows 1 and 2 have the same height.
"Login data" (User/pwd...) occupy row 0 and 1
Button occupy row 2 and 2
For Example
<?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="fev_ventilazione_smartwatch.Pages.MyPageTest">
<ContentPage.Content>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="8*"/>
<RowDefinition Height="1*"/>
<RowDefinition Height="1*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="4*" />
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="4*" />
</Grid.ColumnDefinitions>
<Label Text="TEXT" Grid.Row="0" Grid.Column="0" Grid.RowSpan="2" Grid.ColumnSpan="3" BackgroundColor="Aqua"/>
<Button Text="BUTTON" Grid.Row="1" Grid.Column="1" Grid.RowSpan="2" BackgroundColor="Fuchsia"/>
</Grid>
</ContentPage.Content>
</ContentPage>

I presume it's feasible with an AbsoluteLayout with position
calculations in the codebehind, but that makes the whole page more
complicated than it looks.
Yes you are right. It is feasible with AbsoluteLayout. But its not as complicated as it seems.
Construct your basic elements first:
White container/StackLayout for login details
Login Button.
Facebook/Google buttons in a horizontal StackLayout.
"OR" Label
"Create An Account" Button
Put them in AbsoluteLayout and define their AbsoluteLayout.LayoutFlags as well as AbsoluteLayout.LayoutBounds.
Now key here is to understand that how Absolute Layout works?
You can find that out from this page: Absolute Layout
I have wrote some code to achieve something similar below. But make sure you learn it fully and understand everything before you can use it in your app:
<ContentPage.Content>
<ScrollView BackgroundColor="Silver">
<AbsoluteLayout Margin="30" >
<StackLayout BackgroundColor="White" HeightRequest="150" Spacing="20" Padding="10" VerticalOptions="FillAndExpand"
AbsoluteLayout.LayoutBounds="0,0,1,250" AbsoluteLayout.LayoutFlags="XProportional,YProportional,WidthProportional"
>
<Entry Text="Login" HeightRequest="30"/>
<Entry Text="Password" HeightRequest="30" IsPassword="true" />
<Label Text="FORGOT YOUR PASSOWORD?" HorizontalTextAlignment="End"/>
</StackLayout>
<Button
Text="LOGIN"
FontAttributes="Bold"
BackgroundColor="Maroon"
TextColor="White"
HeightRequest="70"
WidthRequest="70"
AbsoluteLayout.LayoutBounds=".5,215,70,70" AbsoluteLayout.LayoutFlags="XProportional" BorderRadius="35"
/>
<StackLayout
Orientation="Horizontal"
HorizontalOptions="EndAndExpand"
AbsoluteLayout.LayoutBounds="1,270,0.5,70" AbsoluteLayout.LayoutFlags="XProportional,WidthProportional"
>
<Button Text="Facebook"/>
<Button Text="Google"/>
</StackLayout>
<Label Text="OR" HorizontalTextAlignment="Center"
AbsoluteLayout.LayoutBounds="0.5,350,50,50"
AbsoluteLayout.LayoutFlags="XProportional"
/>
<Button
Text="CREATE AN ACCOUNT" Margin="15"
BackgroundColor="White" TextColor="Maroon"
BorderColor="Maroon" BorderWidth="1"
BorderRadius="0"
HorizontalOptions="FillAndExpand"
AbsoluteLayout.LayoutBounds="0.5,370,1,150"
AbsoluteLayout.LayoutFlags="XProportional,WidthProportional"
/>
</AbsoluteLayout>
</ScrollView>
</ContentPage.Content>
And here is the result:
NOTE: You can achieve the same look using RelativeLayout as well.
Hope this helps.
I have a UWP application, I have added a button but when I debug the application, I can't see the button. If I add a texblock or textBox I can see them, but not the button.
I have set IsEnabled to true and visibility to visible but I am not able to solve the problem.
Also I have tried to click in the place where it should be the button but nothing happens.
This happens when I debug in local machine and when I debug in a emulator of windows phone 10.
Thank you so much.
EDIT: the axml code

The margin you set for the Button is too aggressive. The object is now "squeezed". For example set Margin to "120,98,0,200" (or simply "120,98") instead of "120,98,0,510" and it should be visible.
BTW using hardcoded margins to setup the user interface is probably not a good idea. Use for example the Grid with columns and rows instead of margins.
I am creating an application where I use the Hub control, in one of the HubSections I have a Bing Maps MapView. I would like to have that to fill the entire height of the screen, just like with a Hero HubSection, where you just set the HubSection.Background to an ImageBrush.
Now I could probably tweak the MapView Margin and get a dirty and approximate solution to this, but I am not sure if this would work on all screen sizes.
This is what I have now:
This is what I would like:
Do you have any ideas how this can be achieved?
The default HubSection template contains a Grid which divides the Hub's height into three rows:
A placeholder for the Hub's Header
The HubSection's Header
The HubSection's Content
If you want a HubSection to display differently you can apply a customized template.
In the designer open the document outline window and right click on a HubSection. Choose the Edit Template.Edit a Copy... menu. This will create a new HubSectionStyle with a copy of the template.
In the Xaml editor find the template (VS will drop you right there) and scroll down to the bottom where you'll see something like:
<Grid HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Rectangle x:Name="HubHeaderPlaceholder" Grid.Row="0"/>
<Button x:Name="HeaderButton" ContentTemplate="{TemplateBinding HeaderTemplate}" Content="{TemplateBinding Header}" FontWeight="{ThemeResource HubSectionHeaderThemeFontWeight}" FontSize="{ThemeResource HubSectionHeaderThemeFontSize}" Margin="{ThemeResource HubSectionHeaderThemeMargin}" Grid.Row="1" Template="{StaticResource HeaderButtonTemplate}"/>
<ContentPresenter x:Name="ContentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Grid.Row="2"/>
</Grid>
You can edit this to match your needs. The ContentPresenter will contain the HubSection's DataTemplate, so if you want it to start from the top you can change it from Grid.Row 2 to Grid.Row 0 and Grid.RowSpan 3. You could also remove the HeaderButton and HubHeaderPlaceHolder and compress the Grid down if you don't need them, remove the Margin or set Padding to 0, etc.
<Grid HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
<ContentPresenter x:Name="ContentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}"/>
</Grid>

AT LAST after 5 days searching . i found the problem , it was from my video card :
i have hp probook 4540s laptop , it has intel and amd video cards ,so i customize the setting to give me full graphics power , so i open Catalyst Control Center and made the Power give me Maximize Performance (and here the problem started) i changed it to Optimize Performance and all came back to normal (OMG)
This is a guess, but you normally have to give the grid some kind of row or column definition. Here is a grid that defines two rows:
<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Button Content="hello world"></Button>
</Grid>
The above works for me, but the following does NOT work:
<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
<Button Content="hello world"></Button>
</Grid>
I'm currently trying to design a table for contact information including a column for icons like telephone, email or similar symbols and I want to align them with the text from the next column
icon | Telephone:
| +1212354567
icon | Email:
| x#y.com
Is there any Layout which can be compared in functionality to Androids RelativeLayout? I tried to work with the Grid Layout but this seems to be error prone and not exact enough. I don't want to divide my layout into columns and rows, instead I want to describe their position as it is used in RelativeLayout (toLeft, toRight, AlignParentBottom etc.).
The StackPanel can be compared to the LinearLayout, which I want to avoid as it is not suitable for my current design.
Is there any comparison between Windows Phone and Android Layouts on which I can orientate? This one is incomplete and does not give advise for the RelativeLayout.
I know you said you did not want to use a Grid but I feel that you have to in this case.
I would structure it with both a grid and stack panels though.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<!-- Image for first row item -->
<Image Grid.Column="0" Grid.Row="0" Source="icon-url" />
<!-- Container for the details of the first row item -->
<StackPanel Grid.Column="1" Grid.Row="0">
<TextBlock Text="Telephone:" />
<TextBlock Text="+1212354567" />
</StackPanel>
<!-- Image for second row item -->
<Image Grid.Column="0" Grid.Row="1" Source="icon-url" />
<!-- Container for the details of the second row item -->
<StackPanel Grid.Column="1" Grid.Row="1">
<TextBlock Text="Email:" />
<TextBlock Text="x#y.com" />
</StackPanel>
<!-- Just add rows to the grid to continue the list -->
</Grid>
There is no panel that compares, but someone that was adventurous could create one. There are many articles on how to do this, but here's one for reference. http://www.switchonthecode.com/tutorials/wpf-tutorial-creating-a-custom-panel-control
That said, there's no reason not to use Grid for what you're trying to do. It's not "error prone" or "not exact enough". SharedSizeGroup should become your friend here, though.
