Border on stackpanel inside grid cell

Question

I am trying to apply rounded corners to a Stackpanel that is located inside a grid cell. I'm using a tag with CornerRadius. Instead of having the border surround the stackpanel, it instead stretches to surround the parent grid cell. Like this:

I use the following XAML:

<Border Grid.Row="0" Grid.Column="1" BorderBrush="#FF252A30" CornerRadius="5,5,5,5" BorderThickness="2,2,2,2">
    <StackPanel Grid.Row="0" Grid.Column="1" x:Name="stackpanelContactlist" Height="336" Margin="0,113,43,113" Background="#FF252A30" d:LayoutOverrides="Width">

        Content of Stackpanel       

    </StackPanel></Border></Grid>

I'm quite new to WPF, so I'm betting it's something simple - Anyone have any suggestions on how to fix this, so the rounded borded gets applied to the child stackpanel instead of the parent grid cell?

Thanks on advance.

Answer 1

Just move the margin attribute ( Margin="0,113,43,113" ) from StackPanel to the border.

Also you can remove Grid.Row="0" Grid.Column="1" from the stack panel as these are not needed there.
