Viewbox stretching

13 Jan 2022, 19:20

I've got a Viewbox that contains a background Path and some collapsed TextBlocks.

When the visibility of the TextBlocks gets changed to Visible the whole control is meant to expand.

This works as expected in Blend but in Noesis (3.1.2) the Viewbox expands but the Path doesn't. If the TextBlocks are initially set to Visible then the Path is expanded as expected.

 
<Viewbox x:Name="tester" HorizontalAlignment="Left" Height="85" VerticalAlignment="Top" Width="Auto" Margin="74.222,73.707,0,0" RenderTransformOrigin="0.5,0.5">
                    <Grid Width="Auto" Height="85">
                        <Path x:Name="bg_main" Data="F1 M175.994,0 L5,0 C2.25,0 0,2.25 0,5 L0,80 C0,82.75 2.25,85 5,85 L175.994,85 L175.994,0 z" Height="85" VerticalAlignment="Center" Margin="0,0,-35.967,0" Stretch="Fill" Fill="Black"/>
                        <StackPanel x:Name="info_upper" Width="Auto" Orientation="Horizontal" Margin="0,0,-46,0" VerticalAlignment="Top">
                            <TextBlock Height="33" Margin="50,0,20,52" TextWrapping="Wrap" Text="AAAAAAAAA" VerticalAlignment="Center"  RenderTransformOrigin="0.5,0.5" Width="180" TextAlignment="Right" FontSize="36">
                            </TextBlock>
                            <TextBlock Height="33" Margin="50,0,20,52" TextWrapping="Wrap" Text="BBBBBBBBB" VerticalAlignment="Center" RenderTransformOrigin="0.5,0.5" Width="180" TextAlignment="Right" Visibility="{Binding Box_Visible, FallbackValue=Collapsed}" FontSize="36">
                            </TextBlock>
                        </StackPanel>
                    </Grid>
                </Viewbox>

Here's the result in Blend

Any ideas what's going wrong?
