C# WPF - Showing 15-20 User Controls with 4-6 TextBlocks each / Performance issues

I'm struggling with performance in my WPF application.
I have a ListView i populate with some buttons, which contain a bunch of TextBlocks with bindings.
I managed to get Virtualization going, so it seems the same whether its 20 or 2000 i load.
The problem is between 5 and 20. It simply appears that rendering a bunch of somewhat complicated User Controls, is simply too much for basic sub-par hardware.
This is how my Buttons/UserControls in my ListView looks ->
ListViewSample
I feel like WPF should be able to render this on sup-par hardware.
This is the xaml for the ListView:
<ListView ItemsSource="{Binding ButtonModels, IsAsync=True}"
Margin="0"
x:Name="ButtonsListView"
VirtualizingPanel.IsVirtualizing="True"
VirtualizingPanel.IsContainerVirtualizable="True"

tldr; I'm looking for performance tips on how to make this render faster. And this is BEFORE i reach a size in the ListView where my virtualization kicks in (Which works flawlessly)
Thanks in advance!

I managed to find a high performance solution - it just wasn't what i would expect to be better performing.
So instead of having one ListView with a binding, changing the data in the binding and repopulating the Listview, i just spawn a ListView for every collection i have.
It seems weird to me, that having a bunch of ListViews and just collapsing and showing them is more effcient, but it performs absolutely flawlessly.

Strange layout issue MVVM .Net 4.7.2 App controls disappear

I’m building a MVVM app using .Net 4.7.2 that works like a wizard (based on https://www.codeproject.com/KB/WPF/InternationalizedWizard.aspx?display=Print), so no additional frameworks, just the RelayCommand class, a MainWindow.cs that hosts the Main view (the view that has navigation items of the wizard on the left side, and the right side area that hosts the subviews which display based on the stage of the wizard).
Mi issue is that one of my users is experiencing a very strange behaviour with the controls. This is a sample photo of what the application should look like:
And this is a sample photo of what happens to the user. Notice that the image on the bottom left disappears, the bar on the bottom left also disappears, the heading and top text have moved up and clipped inside the window, and the rest of the content in the right side disappears.
Similar to the base InternationalizedWizard App I placed the controls in a grid that has horizontal + vertical alignment set to stretch. The
<Border Background="White" Grid.Column="1" Grid.Row="0">
<ScrollViewer>
<HeaderedContentControl Content="{Binding Path=CurrentPage}" Header="{Binding Path=CurrentPage.DisplayName}" />
</ScrollViewer>
</Border>
I applied this style to the HeaderedContentControl:
<Style TargetType="{x:Type HeaderedContentControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type HeaderedContentControl}">
<StackPanel Margin="2,0">
<Grid Margin="1,1,1,12" RenderTransformOrigin="0.5,0.5">
<Rectangle Fill="{DynamicResource {x:Static SystemColors.AppWorkspaceBrushKey}}" Height="3" Margin="10,-4" Opacity="0.6" RadiusX="8" RadiusY="8" VerticalAlignment="Bottom" />
<ContentPresenter ContentSource="Header" TextBlock.FontSize="22" TextBlock.FontWeight="DemiBold" TextBlock.Foreground="Black" HorizontalAlignment="Center" VerticalAlignment="Center" OpacityMask="Black" />
<Grid.Effect>
<DropShadowEffect Opacity="0.1" />
</Grid.Effect>
<Grid.RenderTransform>
<RotateTransform Angle="0" />
</Grid.RenderTransform>
</Grid>
<Grid>
<Rectangle Fill="{TemplateBinding Background}" />
<ContentPresenter ContentSource="Content" />
</Grid>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
The scrollviewer only scrolls up and down if the content is large, but in this case the content should fit fine so as expected the user won't see the scrollviewer.
The image from the bottom left that strangely disappear was placed in the column 0, row 0 of the grid a custom margin so it remains in that area:
<Image Grid.Column="0" Grid.Row="0" Source="..\Assets\SplashLogo.png" HorizontalAlignment="Center" VerticalAlignment="Bottom" Stretch="None" Margin="20,20,20,20"/>
The first page (e.g. Welcome) that displays has another grid with two
<Grid>
<Grid.RowDefinitions>
<RowDefinition MinHeight="30" MaxHeight="60"/>
<RowDefinition Height="*" MinHeight="200"/>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Text="{x:Static res:Strings.SomeText_Description}" FontSize="15" FontWeight="Light" Margin="20,0,20,0" TextWrapping="Wrap" />
<StackPanel Grid.Row="1" Orientation="Horizontal" VerticalAlignment="Center" HorizontalAlignment="Center">
<Label Content="{x:Static res:Strings.WelcomeView_SomeText}" FontSize="15" FontWeight="Light" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="20,0,20,0" />
<TextBox Text="{Binding Path=SomeInput, UpdateSourceTrigger=PropertyChanged}" Height="25" Width="200" FontSize="15" FontWeight="Light" HorizontalAlignment="Left">
<TextBox.InputBindings>
<KeyBinding Key="Enter" Command="{Binding MoveNextFromWelcomeCommand}" CommandParameter="{Binding Path=Text, RelativeSource={RelativeSource AncestorType={x:Type TextBox}}}" />
</TextBox.InputBindings>
</TextBox>
</StackPanel>
</Grid>
But the contents of the stack panel completely disappear of view.
Finally, the bottom area of the main view is created in a border like this one, which also completely disappears from view:
<Border Grid.Column="0" Grid.Row="1" Background="LightGray" Grid.ColumnSpan="2">
<Grid >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Grid.Row="1" Grid.ColumnSpan="5" Margin="4" FontSize="15" Text="{Binding Path=ReportStatus}" VerticalAlignment="Center" Visibility="{Binding Path=ShowReportStatus}" />
<!-- NAVIGATION BUTTONS -->
<Grid Grid.Column="2" Grid.Row="0" Grid.IsSharedSizeScope="True" HorizontalAlignment="Right" >
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="Buttons" />
<ColumnDefinition SharedSizeGroup="Buttons" />
<ColumnDefinition SharedSizeGroup="Buttons" />
<ColumnDefinition SharedSizeGroup="Buttons" />
</Grid.ColumnDefinitions>
<Button Grid.Column="1" Grid.Row="0" Command="{Binding Path=MovePreviousCommand}" Style="{StaticResource movePreviousButtonStyle}" />
<Button Grid.Column="2" Grid.Row="0" Command="{Binding Path=MoveNextCommand}" Style="{StaticResource moveNextButtonStyle}" />
<Button Grid.Column="3" Grid.Row="0" Command="{Binding Path=CancelCommand}" Style="{StaticResource cancelButtonStyle}" />
</Grid>
</Grid>
</Border>
I initially thought there could be an issue with the version of .NET or OS, but my users has the latest version of Windows 10 Enterprise (10.0.17134) and dual screen with 1: 3840x2160 2: 2560x1600. I have tried to replicate that on my own computer but everything works fine for me. I also tested the App in Windows 7 and it works with no issues.
I really don't understand what could be happening, does it have anything to do with the user's DPI settings or any accessibility feature?

It's not working because you have the BorderBrush hard-coded in the attribute, which takes precedence. Update so that the style is not a resource, and add the Trigger to the Border itself.

Border is added only to the first text block in WPF

Edit : I realized what the problem is, when I add the border, The second TextBlock sits on top of the first TextBlock. Still have to figure out why this is happening.
Original question:
I have a number of TextBlocks in my xaml. I want to add a border around some textblocks. I tried the following methods.
Method 1:
<Style x:Key="BorderForTextBlock" TargetType="{x:Type Border}">
<Setter Property="BorderThickness" Value="1" />
<Setter Property="BorderBrush" Value="Black" />
</Style>
<TextBlock1../>
<Border Style="{StaticResource BorderForTextBlock}">
<TextBlock2.../>
</Border>
Method 2:
<TextBlock1../> //This is where the border is added.
<Border BorderThickness="1" BorderBrush="Black">
<TextBlock2 ..../> //This is where I want to add the border
</Border>
A border is added only to the first TextBlock in the xaml no matter to which TextBlock I add the border. I don't want the border on the first TextBlock. I have no clue why this is happening.
This is my xaml :
<Grid Background="LightYellow" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" ></ColumnDefinition>
<ColumnDefinition Width="3.5*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="28*" ></RowDefinition>
<RowDefinition Height="120*" ></RowDefinition>
<RowDefinition Height="28*"></RowDefinition>
<RowDefinition Height="74*"></RowDefinition>
</Grid.RowDefinitions>

</Border>
<TextBlock Grid.Row="1" Margin="10,0,5,0" FontWeight="SemiBold" Text="{x:Static res:Resources.source2}"/>
<RichTextBox Background="LightYellow" Margin="0,0,0,0" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.CanContentScroll="True" Grid.Row="1" Grid.Column="1" IsReadOnly="True" >
<FlowDocument>

<Run Text="{Binding content2, Mode=TwoWay}"/>
</Paragraph>
</FlowDocument>
</RichTextBox>
<TextBlock Grid.Row="2" Margin="10,0,5,0" FontWeight="SemiBold" Text="{x:Static res:Resources.source3"/>
<TextBlock Text="{Binding content3, Mode=TwoWay}" Margin="0,0,0,0" Grid.Row="2" Grid.Column="1" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.CanContentScroll="True" TextWrapping="Wrap"/>
<TextBlock Grid.Row="3" Margin="10,0,5,0" FontWeight="SemiBold" Text="{x:Static res:Resources.source4}"/>
<TextBox Text="{Binding content4, Mode=TwoWay}" Margin="0,0,0,0" Grid.Row="3" Grid.Column="1" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Auto"
ScrollViewer.CanContentScroll="True" TextAlignment="Left" TextWrapping="Wrap" Background="LightYellow" IsReadOnly="True"/>
</Grid>

instead of
<Border BorderBrush="Black" BorderThickness="1">
<TextBlock x:Name="txtBlock1" FormatTest:FormattedTextBehavior.FormattedText="{Binding Path= content1}" Margin="0,0,0,0" Grid.Row="0" Grid.Column="1" TextWrapping="Wrap"/>
</Border>
Have
<Border Grid.Row="0" Grid.Column="1" BorderBrush="Black" BorderThickness="1">
<TextBlock x:Name="txtBlock1" FormatTest:FormattedTextBehavior.FormattedText="{Binding Path= content1}" Margin="0,0,0,0" TextWrapping="Wrap"/>
</Border>
This should solve the issue with placement of text blocks
This is how it looks at my end

You can use style with trigger and put the style either in windows resources or app resources depending upon scope you want
<Window x:Class="WpfApplication2.MainWindow"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Grid.Resources>
<Style x:Key="NotCalledBorder" TargetType="{x:Type Border}">
<Setter Property="BorderThickness" Value="1" />
<Setter Property="BorderBrush" Value="Black" />
<Setter Property="Height" Value="20"/>
<Setter Property="Width" Value="30"/>
<Setter Property="HorizontalAlignment" Value="Left"/>

<Style TargetType="TextBlock">

Conditional style in WPF. Adding border to two textblocks only. You can apply style and add to as many as you want

Grid Border / Gap between cells

I've created a ControlTemplate that contains a Grid with two rows.
Sadly, there appears to be a single pixel gap between the cells.
How do I remove the gap?
Here's a screenshot showing the gap:
...and here's the XAML:
<Window x:Class="MAQButtonTest.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="695" Width="996">
<Window.Resources>
<Style TargetType="TextBlock">
<Setter Property="OverridesDefaultStyle" Value="True"/>
</Style>
<ControlTemplate TargetType="Button" x:Key="ButtonTemplate">
<Grid Width="444" Margin="0" ShowGridLines="False">
<Grid.RowDefinitions>
<RowDefinition Height="51" />
<RowDefinition Height="36" />
</Grid.RowDefinitions>
<Grid Grid.Row="0" Background="#286c97">
<TextBlock>This is the first piece of text</TextBlock>
</Grid>
<Grid Grid.Row="1" Background="#5898c0">
<ContentPresenter Grid.Row="0" />
</Grid>
</Grid>
</ControlTemplate>
</Window.Resources>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="300" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid Grid.Column="0" Background="#e9f1f6"></Grid>
<Grid Grid.Column="1" Background="#d2e3ed">
<StackPanel>
<TextBlock FontFamily="Segoe UI" FontSize="22" FontWeight="Medium" Margin="52,58,0,0" Foreground="#0c3d5d">Your Quizzes <TextBlock FontFamily="Segoe UI" FontSize="18" FontWeight="Medium" Foreground="#0c3d5d">(7)</TextBlock></TextBlock>
<Grid Margin="0,20,0,0">
<Button Width="444" Background="{x:Null}" BorderThickness="0" Template="{StaticResource ButtonTemplate}" Click="DoSomething" BorderBrush="#032135">
<TextBlock Margin="6,2.8,0,0" FontFamily="Segoe UI" FontSize="19" Foreground="#032135" FontWeight="Medium">This is a second piece of text</TextBlock>
</Button>
</Grid>
</StackPanel>
</Grid>
</Grid>
</Window>

Just add SnapsToDevicePixels="True" in your template grid
<ControlTemplate TargetType="Button" x:Key="ButtonTemplate">
<Grid Width="444" Margin="0" ShowGridLines="False" SnapsToDevicePixels="True">
<Grid.RowDefinitions>
<RowDefinition Height="51" />
<RowDefinition Height="36" />
</Grid.RowDefinitions>
<Grid Grid.Row="0" Background="#286c97">
<TextBlock>This is the first piece of text</TextBlock>
</Grid>
<Grid Grid.Row="1" Background="#5898c0">
<ContentPresenter Grid.Row="0" />
</Grid>
</Grid>
</ControlTemplate>

Set
SnapsToDevicePixels="True"
On grids in template or button, but better just create new style with SnapsToDevicePixels="True" setter and template inside style.
