UWP: Cannot make ListView scrollable

I have a page with a simple grid (2x2). In one grid on the bottom left corner is another Grid and inside this grid is a ListView bound to a collection. Entries can be added to the collection so the ListView grows in height (height of ListView is set to auto, so that all space available is used).
What I want is, if all available space (from the screen height) is used, scrollbars for the ListView should appear and should be usable. Funny (unfunny) thing is: scrollbars do appear but I cannot use them, I cannot scroll the ListView with the vertical scrollbar that appears when I hover the ListView.
It works, when I set the height of the ListView to a fixed value, but I don't want it that way, because then it doesn't use all the available space on the screen.
This is the XAML of the page (I removed some parts for demonstration purposes) :

Can someone spot why it is behaving this way?

You need to set the height of the second row to "*" for both grids.

How to link external Xaml page to a Grid in Universal Windows Platform?

I want to link an external .xaml file into a grid in my Universal Windows Platform App.
This is the folder structure:
I want to link ListView.xaml into a grid which is declared inside MainPage.xaml

So this is what I'm planning to do with my app :
I will be having different external pages like ListView.xaml and whenever user clicks a link or a tab, the part where the page is linked should be changed with the page that has been asked for.
Thanks. Any other ideas are also appreciated.

To include a Page inside of another, use the Frame object:
<Grid Grid.Row="1">
<Frame x:Name="MainFrame"></Frame>
</Grid>
Then, to load a page inside of the Frame, just call the Navigate method:
this.MainFrame.Navigate(typeof(TodoGrocery.ListView));

As Kory said, you can know how to do what you want in UWP by reading Navigation chapter in How-to guides for Windows 10 apps.
The key point here is using Frame and Frame.Navigate methods. The frame hosts the pages and keeps the navigation history.
You create as many different page types as needed to present the content in your app, and then navigate to those pages by calling the Navigate method and passing in the type of the page to navigate to. You can also pass in a parameter object to initialize the page to a particular state.
So you can change your MainPage.xaml like following to link ListView.xaml:
<Page x:Class="TodoGrocery.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="using:TodoGrocery"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition Height="40"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid x:Name="gridView" Grid.Row="0" HorizontalAlignment="Stretch" Margin="0,0,0,0" VerticalAlignment="Top" Height="40" Background="#3A5194">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="50"/>
</Grid.ColumnDefinitions>
<Button x:Name="backButton" BorderThickness="0" Grid.Column="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Background="Transparent">
<SymbolIcon Symbol="Back" Foreground="White" HorizontalAlignment="Center" VerticalAlignment="Center" Width="40" Height="40"/>
</Button>
<TextBlock x:Name="title" Grid.Column="1" HorizontalAlignment="Center" FontSize="20" VerticalAlignment="Center" Foreground="White" Text="Todo Grocery"></TextBlock>
<Button x:Name="moreButton" BorderThickness="0" Grid.Column="2" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Background="Transparent">
<SymbolIcon Symbol="More" Foreground="White" HorizontalAlignment="Center" VerticalAlignment="Center" Width="40" Height="40"/>
</Button>
</Grid>
<Grid Grid.Row="1">
<Frame x:Name="MyFrame">
<local:ListView />
</Frame>
</Grid>
</Grid>
</Page>
Or just add a Frame in Grid:
<Grid Grid.Row="1">
<Frame x:Name="MyFrame" />
</Grid>
And in code-behind, using
MyFrame.Navigate(typeof(TodoGrocery.ListView));

WPF Listbox grows outside screen size (MVVM light)

I have a typical MVVM structure. A mainwindow consists of some labels and a viewmodel (bound as ContentControl). This viewmodel has a listbox where I add entries. As the list grows the height of my viewmodel grows as well and thus the height of the whole application. Unfortunately the size doesn't stop at the edge of the screen and just grows out of the screen. I tried all the different size-restrictions on the mainwindow, the viewmodel is stretched in both dimensions.
Furthermore, I tried to get a scrollbar for the listbox but didn't succeed (or it's just there but not enabled if I force it.)
How can I restrict the maximal size to be the resolution of the screen (fullscreen) and get a scrollbar for the listbox when the size is reached?
€: Okay, here should be the relevant part of my code. I tried a fixed size of 1024x768 but even that doesn't work.
MainWindow.xaml
<Window x:Class="SWS.MainWindow"
DataContext="{Binding Main, Source={StaticResource Locator}}"
Width="1024"
Height="768"
MaxWidth="1024"
MaxHeight="768">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<ContentControl Grid.Row="0" Content="{Binding CurrentViewModel}" />
</Grid>
</Window>
The ViewModel in question
<UserControl x:Class="SWS.Views.ProgramView"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<DockPanel Grid.Row="0">
<Label Width="65" Content="{x:Static p:Resources.PrV_Number}" />
<Label Width="75" Content="{x:Static p:Resources.PrV_Weight}" />
<Label Width="55" Content="{x:Static p:Resources.PrV_Action}" />
<Label Content=" " />
</DockPanel>
<ListBox Grid.Row="1"
VerticalAlignment="Stretch"
ItemsSource="{Binding ParticleCollection}"
ScrollViewer.CanContentScroll="True"
ScrollViewer.VerticalScrollBarVisibility="Auto">
<ListBox.ItemTemplate>
<DataTemplate>
<DockPanel>
<TextBlock Text="{Binding ID}" Width="53" />
<TextBlock Text="{Binding Weight, StringFormat=F4}" Width="65" />
<TextBlock Text="{Binding Action}" Width="52" />
</DockPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</UserControl>

You need to set the row height to * on your Window for ContentControl and your ListBox in UserControl to fill available space than try to get what it needs.
This worked fine:
MainWindow.xaml:
<Window x:Class="SWS.MainWindow"
DataContext="{Binding Main, Source={StaticResource Locator}}"
Width="1024"
Height="768"
MaxWidth="1024"
MaxHeight="768">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<ContentControl Grid.Row="0" Content="{Binding CurrentViewModel}" />
</Grid>
</Window>
and UserControl:
<UserControl x:Class="SWS.Views.ProgramView"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
...
</Grid>
</UserControl>
Could also do this in a couple more ways:
In your Window you can just remove the <Grid.RowDefinitions>...<Grid.RowDefinitions> completely. The default behavior is what your looking for.
When you have more than 1 row you can either choose to specify Height="*" or just remove the Height Property from the RowDefinition
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition />
</Grid.RowDefinitions>

I need to put a label in the right hand corner of my popup in XAML

Here is my code. I have tried several things to get the label in the top right hand corner of the popup and make it stay there, but nothing has worked.
Thanks for your help!
XAML:
<Window x:Class="ValidationWPF.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
xmlns:local="clr-namespace:ValidationWPF"
Title="MainWindow" mc:Ignorable="d"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" d:DesignHeight="259" d:DesignWidth="420" SizeToContent="WidthAndHeight">
<Grid Height="129" Width="345">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="514*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="0" />
<RowDefinition Height="251*" />
</Grid.RowDefinitions>
<Button Content="Errors" Height="23" HorizontalAlignment="Left" Name="button1" VerticalAlignment="Top" Width="75" Grid.Column="1" Grid.Row="1" Margin="132,12,0,0" MouseEnter="button1_MouseHover">
</Button>
<Popup AllowsTransparency="True" PlacementTarget="{Binding ElementName=button1}" StaysOpen="True" AllowDrop="True" Name="PopUp1" PopupAnimation="Scroll">
<Popup.Child>
<Border BorderBrush="White" BorderThickness="3, 3, 0, 0">
<Border BorderBrush="Black" BorderThickness="3, 3, 3, 3">
<TextBlock Background="Salmon">
<Label Background="AliceBlue" Foreground="Black" HorizontalAlignment="Stretch" HorizontalContentAlignment="Right" MouseDown="mouse_DownHandeled" AllowDrop="False" Margin="100,100,0,0">
x
</Label>
<local:ValidationUserControl/>
</TextBlock>
</Border>
</Border>
</Popup.Child>
</Popup>
</Grid>
</Window>
As you see, I have a popup with a label that has an X in it. The label is fully functional. Now I just need it to look like a normal popup with the label in the top right hand corner.

Try this:
<TextBlock Background="Salmon" MinWidth="150" MinHeight="150" VerticalAlignment="Top">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="120" />
<ColumnDefinition Width="30" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="30" />
<RowDefinition Height="120" />
</Grid.RowDefinitions>
<Label Grid.Row="0" Grid.Column="1" Background="AliceBlue" Foreground="Black" VerticalAlignment="Top" AllowDrop="False">
X
</Label>
</Grid>
</TextBlock>

UserControl Grid get's displayed with Portrait sizing in Landscape mode

I have this XAML for a UserControl:
<UserControl x:Class="SW.Resources.Controls.HistoryProgressBox"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
FontFamily="{StaticResource PhoneFontFamilyNormal}"
FontSize="{StaticResource PhoneFontSizeNormal}"
Foreground="{StaticResource PhoneForegroundBrush}"
d:DesignHeight="480" d:DesignWidth="480">
<Grid x:Name="LayoutRoot" Style="{StaticResource AppBackgroundStyle}">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="223" />
<ColumnDefinition Width="223" />
<ColumnDefinition Width="10" />
</Grid.ColumnDefinitions>
<TextBlock x:Name="TitleText" Style="{StaticResource TitleListItemStyle}" Text="41xxfd" TextWrapping="Wrap" Grid.ColumnSpan="2"/>
<TextBlock x:Name="leftValue" HorizontalAlignment="Right" Style="{StaticResource DetailListItemStyle}" Text="Category: " Grid.Row="1" Grid.Column="0"/>
<TextBlock x:Name="rightValue" Style="{StaticResource DetailListItemValueStyle}" Text="tv" Grid.Row="1" Grid.Column="1" />
<TextBlock x:Name="subLeftValue" HorizontalAlignment="Right" Style="{StaticResource DetailListItemStyle}" Text="Size: " Grid.Row="2" Grid.Column="0" />
<TextBlock x:Name="subRightValue" Style="{StaticResource DetailListItemValueStyle}" Text="400MB" Grid.Row="2" Grid.Column="1" />
<Rectangle Fill="Red" x:Name="progressColor" Grid.RowSpan="4" Grid.Column="2"/>
</Grid>
It looks exactly as I want it to in Portrait. But in landscape, the control ends early. Ideally I would have this control stretch to cover the entire screen. Is this possible to do without having to do any extra code to handle the switch to Landscape?

If you put it inside another grid on the page it should resize to fit the page.
You may want to use percentage based column widths so the columns also resize.
e.g.
<Grid.ColumnDefinitions>
<ColumnDefinition Width="223*" />
<ColumnDefinition Width="223*" />
<ColumnDefinition Width="10*" />
</Grid.ColumnDefinitions>
