How to make a child element limited in size by its parent in WPF?

Question

I have a StackPanel that is larger than its parent Grid . I confirmed that using Snoop WPF Spy. Width set to the default value. How to limit it?

I do not like the ViewBox solution because it changes my text and I want it to be wrapped / cropped.

Change XAML on request

 <Grid> <StackPanel Orientation="Horizontal"> <Border BorderBrush="Black" BorderThickness="1" Width="{ Binding BorderScreenShot }" Margin="0,-8,0,0"> <Image ToolTip="Some Text" Cursor="Hand" Source="{ Binding Image }" Stretch="Fill" Visibility="{ Binding ImageVisibility }" MouseLeftButtonUp="Image_MouseLeftButtonUp" /> </Border> <StackPanel Orientation="Vertical" Margin="10,0,0,0"> <TextBlock Text="{ Binding Name }" TextWrapping="Wrap" /> <TextBlock Text="{ Binding LongText }" TextWrapping="Wrap" /> <StackPanel Orientation="Horizontal"> <TextBlock Text="{ Binding Category }" /> <TextBlock Text="{ Binding Version }" /> </StackPanel> </StackPanel> </StackPanel> </Grid> 

Answer 1

You can try changing the StackPanel to a DockPanel (with the corresponding DockPanel.Dock properties for children).

This will mimic the effect of the StackPanel, but allow children to be limited.

Or use a WrapPanel instead of a StackPanel.

StackPanels have an infinite client size, so nothing inside the StackPanel will wrap or crop without setting explicit parameters (instead, the StackPanel just grows to fit the content).

It is not possible for a child to be larger than its parent, unless its contents are larger. If you want to trim text, you can use TextBlock.TextTrimming = WordEllipsis/CharacterEllipsis . This will lead to the desired behavior if my interpretation of the question is correct.

However, this does not work with StackPanel . As the other answer suggests, you can use a DockPanel or Grid to host content.

Alternatively, you can wrap the StackPanel in a ScrollViewer and use the scroll bar to handle overflow.

Update This should fix it.

  <DockPanel> <Border DockPanel.Dock="Left" BorderBrush="Black" BorderThickness="1" Width="{ Binding BorderScreenShot }" Margin="0,-8,0,0"> <Image ToolTip="Some Text" Cursor="Hand" Source="{ Binding Image }" Stretch="Fill" Visibility="{ Binding ImageVisibility }" MouseLeftButtonUp="Image_MouseLeftButtonUp" /> </Border> <StackPanel DockPanel.Dock="Bottom" Orientation="Horizontal"> <TextBlock Text="{ Binding Category }" /> <TextBlock Text="{ Binding Version }" /> </StackPanel> <TextBlock DockPanel.Dock="Top" Text="{ Binding Name }" TextWrapping="Wrap" /> <TextBlock Text="{ Binding LongText }" TextTrimming="WordEllipsis" TextWrapping="Wrap" /> </DockPanel>

If you do not want to compress the content, there is no other way to limit it - especially since the images are involved.

This pretty much leaves you with ScrollViewer , which was designed specifically for this scenario. Personally, I like to combine the ability to zoom in / out using the ScrollViewer function. This gives your users more options in how they view your content.
