TextBlock fills vertical space
I want to create TextBlock
(or some other element with text in it just for display) that is vertical (-90 angle angle), but I want that element to fill the vertical space it contains, but have a certain horizontal amount (I use vertical and horizontal words instead of height and width, as it swaps when I have TextBlock
go vertical) and align it with the left side of the container.
I believe I understand how to do it TextBlock
vertically using RenderTransform
or LayoutTransform
. However, I can't get the "docking" to work fine, whenever I change the vertical aspect of the container, it TextBlock
grows horizontally instead of vertically.
Here's what I have:
<UserControl
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"
x:Class="AttendanceTracker.StudentView"
x:Name="UserControl" Height="172.666" Width="417.333">
<StackPanel x:Name="LayoutRoot" Orientation="Horizontal">
<Border BorderBrush="Black" BorderThickness="1" RenderTransformOrigin="0.5,0.5" Background="#52FFFFFF" Width="139.667">
<TextBlock Text="My Title" TextWrapping="Wrap" FontSize="18.667" TextAlignment="Center" Foreground="White" Margin="-58.509,68.068,49.158,70.734" Background="Black" RenderTransformOrigin="0.5,0.5" Width="147.017" d:LayoutOverrides="Height">
<TextBlock.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform Angle="-90"/>
<TranslateTransform/>
</TransformGroup>
</TextBlock.RenderTransform>
</TextBlock>
</Border>
</StackPanel>
Change the height of the UserControl and you will notice that it TextBlock
grows in the horizontal aspect instead of the desired vertical aspect.

If I understand you correctly, this should point in the right direction:
<StackPanel Orientation="Horizontal">
<TextBlock Background="Red" Text="My Title">
<TextBlock.LayoutTransform>
<TransformGroup>
<RotateTransform Angle="90"/>
</TransformGroup>
</TextBlock.LayoutTransform>
</TextBlock>
</StackPanel>
The key is to use LayoutTransform
, not RenderTransform
. This ensures that a different layout happens after the conversion. Otherwise, the layout system uses the original bounding box for layout TextBlock
.
Other than that, I just got rid of all the Blend cruft I created to see what was going on. Here's the result:
