StackPanel Orientation stops page load - xaml

First to explain what I am doing here, I want to create a page that list a large number of grouped objects. Selecting an object binds that information to a display on the left. Everything works fine till I change the MainStack Orientation to Horizontal. Once that is changed the page no longer loads. No errors are thrown. When stepping through the process the code behind steps through as it should.
I know its the XAML but am baffled by the cause. It works fine under two circumstances.
If I drop the mainstack stack panel and instead make the display group the header of the GridView it works.
If I put the MainStack orientation to Vertical it loads fine.
Here is the code that does not load:
<StackPanel Name="MainStack" Orientation="Horizontal" Grid.Row="2" >
<StackPanel Name="Stack" Width="480" >
<TextBlock Text="{Binding Nname}" Margin="0,0,0,20" Style="{StaticResource SubheaderTextBlockStyle}" MaxHeight="60"/>

GridView ItemTemplate Full Width

My question is: how can I stretch the DataTemplate to the full width of the screen. I've tried many solutions but they does not work.
I've tried HorizontalContentAlignment, setting GridView.ItemContainerStyle and etc. But nothing works. Can anybody explain me how can I do this?
Here is part of my code:
<Grid Style="{StaticResource GeneralAppBackground}">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Pivot x:Name="AccountInfoOptions" Grid.Row="1">
<PivotItem Header="История">
<GridView ItemsSource="{x:Bind CheckoutList}" Margin="5,0,5,0">
<GridView.ItemTemplate>
<DataTemplate x:DataType="data:UserCheckout">
<StackPanel Orientation="Horizontal" BorderBrush="Transparent" Background="White" Padding="5" Margin="0,5,0,0">
<StackPanel Grid.Column="0" Orientation="Vertical" VerticalAlignment="Center" Margin="0,0,10,0">
<TextBlock FontSize="14" Text="{x:Bind CheckoutDate}" Foreground="#979797" />
<TextBlock FontSize="14" Text="{x:Bind CheckoutTime}" Foreground="#979797" />
</StackPanel>
<StackPanel Grid.Column="1" VerticalAlignment="Center">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{x:Bind CheckoutSum}" FontSize="22" FontWeight="Bold" />
<Image Source="/Assets/TengeIcon.png" Width="20" Margin="5,0,0,0"/>
</StackPanel>
<TextBlock Text="{x:Bind CheckoutTitle}" TextAlignment="Center" />
</StackPanel>
</StackPanel>
</DataTemplate>
</GridView.ItemTemplate>
<GridView.ItemContainerStyle>
<Style TargetType="GridViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</GridView.ItemContainerStyle>
</GridView>
</PivotItem>
</Pivot>
The key to making it work, is changing the ItemsPanelTemplate. Define it as a page resource:
<Page.Resources>
<ItemsPanelTemplate x:Key="ItemsPanelTemplate">
<ItemsStackPanel />
</ItemsPanelTemplate>
</Page.Resources>
Now set it as the ItemsPanel for your GridView:
<GridView ItemsSource="{x:Bind CheckoutList}"
Margin="5,0,5,0"
ItemsPanel="{StaticResource ResourceKey=ItemsPanelTemplate}">
This will allow individual items to stretch across the full width. You will still need to replace the root StackPanel in your DataTemplate with a Grid as Nikita suggested:
<DataTemplate x:DataType="local:UserCheckout">
<Grid BorderBrush="Transparent" Background="White" Padding="5" Margin="0,5,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0" Orientation="Vertical" VerticalAlignment="Center" Margin="0,0,10,0">
<TextBlock FontSize="14" Text="{x:Bind CheckoutDate}" Foreground="#979797" />
<TextBlock FontSize="14" Text="{x:Bind CheckoutTime}" Foreground="#979797" />
</StackPanel>
<StackPanel Grid.Column="1" VerticalAlignment="Center">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{x:Bind CheckoutSum}" FontSize="22" FontWeight="Bold" />
<Image Source="/Assets/TengeIcon.png" Width="20" Margin="5,0,0,0"/>
</StackPanel>
<TextBlock Text="{x:Bind CheckoutTitle}" TextAlignment="Center" />
</StackPanel>
</Grid>
</DataTemplate>
You already have the Grid.Column property set correctly for the inner StackPanels. It seems you were attempting to use a Grid there before.

Set ContentDialog to show on bottom of page in UWP

I have several ContentDialogs in a RelativeLayout and want them to appear or have the the vertical alignment to "bottom". But it seems that no matter what I try the dialogs always appear on the top of the screen.
This is how they look now
Any ideas?

It seems the positioning of ContentDialog instances is not in the hands of the developer, at least not without custom versions of it. Afaik the OS will decide where to place the dialog for you.
See here for more information:
http://www.reflectionit.nl/blog/2015/windows-10-xaml-tips-messagedialog-and-contentdialog
So if positioning of the dialog is critical then you might have to create a custom control.

XAML Element responsive width on Orientation change

I am building a Windows 8.1 Universal app. On the orientation change for the phone, the outer "Grid" element doesn't change in width when the phone is switched to Landscape mode (and vice versa if the app is originally opened in landscape - doesn't change width when orientation=portrait). The Width is bound to the PivotItem Width and the PivotItem fills the entire screen on orientation change but the Grid does not.

Windows Store App - XAML - Why is the Textblock is bigger the StackPanel?

I have the below XAML and it does not do what I expect it to do.
<StackPanel Background="{Binding EwsColour}" Visibility="{Binding EwsVisibility}" HorizontalAlignment="Center" VerticalAlignment="Center" >
<TextBlock Text="EWS" Style="{StaticResource SubheaderTextBlockStyle}" VerticalAlignment="Top" FontWeight="SemiBold" HorizontalAlignment="Center" />
<TextBlock Text="18" Style="{StaticResource SubheaderTextBlockStyle}" FontWeight="SemiBold" FontSize="100" />
</StackPanel>
I end up with this
I don't understand why the TextBlock that has 18 in, is growing bigger then then StackPanel. Can anyone tell me why?
After seeing Chris W''s comment I checked the Style in generic.xaml.
<Style x:Key="SubheaderTextBlockStyle" TargetType="TextBlock" BasedOn="{StaticResource BaseTextBlockStyle}">
<Setter Property="FontSize" Value="26.667"/>
<Setter Property="FontWeight" Value="Light"/>
<Setter Property="LineHeight" Value="30"/>
</Style>
I had no idea that there was a LineHeight property. Overriding it so that its the same as the font size (or bigger actually creates a better UX) stops this from happening.
<StackPanel Background="{Binding EwsColour}" Visibility="{Binding EwsVisibility}" HorizontalAlignment="Center" VerticalAlignment="Center" >

<TextBlock Text="18" Style="{StaticResource SubheaderTextBlockStyle}" FontWeight="SemiBold" FontSize="100" LineHeight="110" />
</StackPanel>
