I want to express it like this picture
I wrote a letter in the text on Border,
The letters are covered like in the picture.
Can you make this stick out like the picture below?
How can solve this?
this is my xaml code

If you put the textblock in a canvas, that will not clip.
<StackPanel
HorizontalAlignment="Center"
VerticalAlignment="Center">
<TextBlock
Margin="5"
Text="{Binding Path=Priority}" />
<Canvas>
<TextBlock
Text="{Binding Path=TaskName}" />
</Canvas>
</StackPanel>

Does anyone know why this is?

You have set twice the window style here:
<Window.Style>
<Style TargetType="{x:Type Window}">
<Setter Property="Background" Value="{StaticResource WindowBrush}"/>
</Style>
And here:
WindowStyle="None"
I'm not close to a VS right now but it seems to be the problem.

I'm currently trying to apply styling to my menuItem. I had to center it's header inside the control, and the only way to it that I had found is this:
<MenuItem>
<MenuItem.Header>
<TextBlock Text="About" VerticalAlignment="Center" HorizontalAlignment="Center"/>
</MenuItem.Header>
</MenuItem>
Now, I am trying to apply styles, but I can't seem to manage to bind the textboxes' text from style to the actual xaml value.
My style:
<Style x:Key="MenuItemBaseStyle" TargetType="MenuItem">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Background" Value="#0a99f3" />
<Setter Property="Foreground" Value="White"/>
</Trigger>
</Style.Triggers>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type MenuItem}">
<Grid Background="{TemplateBinding Background}">
<MenuItem>
<MenuItem.Header>
<TextBlock Text="{TemplateBinding Text}" />
</MenuItem.Header>
</MenuItem>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
TemplateBinding is just one of the approaches I tried, though none worked even remotely close.

<StackPanel Margin="10" Orientation="Vertical">

<Image Width="15" Height="15" Source="/BoardiesSMSServer;component/images/add.png" Tag="{Binding logID}" />

</StackPanel>
</DockPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Within my DockPanel within the DataTemplate I have a StackPanel which contains various TextBlocks from the array that is passed into the binding.
In one of the StackPanels you will see you will see a TextBlock that binds to the element of contactNameOrPhoneNumber.
What I want to be able to do is if another value from the binding is null then I add a TextBlock for the contactNameOrPhoneNumber` element and alongside it have another TextBlock which contains another element of number``, if the other binding value is not null then this extra textblock of number is not added.
So in simple terms, what I want to be able to do is within the DataTemplate have a conditional if statement of if binding value == null add textblock to stackpanel else don't add textblock.

You can do that with Style + Triggers something like this:
<TextBlock>
<TextBlock.Style>
<Style TargetType="TextBlock">
<Style.Triggers>
<DataTrigger Binding="{Binding PropertyName}" Value="{x:Null}">
<Setter Property="Visibility" Value="Collapsed"/>
</DataTrigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>
Also you can create IValueConverter say ObjectToVisibilityConverter which will take input your property and if property is null return Visibility.Collapsed else return Visibility.Visible.
You can then bind property with Visibility value of TextBlock via Converter.
<TextBlock Visibility="{Binding PropertyName,
Converter={StaticResource ObjectToVisibilityConverter}}"/>

Let's say I have a View/Page something like below:
Category1 Category2 ......... Category(n)
Tile1 Tile1 Tile1
Tile2 Tile2 Tile2
..... ..... .....
..... ..... .....
Tile(n) Tile(n) Tile(n)

But the problem is that I don't know the binding of ItemsSource of the ListBox. So, I don't get the Output as shown above.
Here is how my database tables look like:

You can simply bind to Design_Master_Category that store collection of Design_Master_TileItems, for example :
......
<ListBox Grid.Row="1" x:Name="lst"
ItemsSource="{Binding Design_Master_TileItems} >
......
If you find that the property is empty at run-time as stated in comment, it means the problem is not at your binding. You need to fix your query. I am by no means well-experienced with EF, but here is my suggestion :
try to use .Include(o => o.Design_Master_TileItems) function when querying Design_Master_Category table. [Reference]
