<Border Name="border" Margin="16">
<StackPanel Orientation="Vertical" Margin="5,0,0,0">
<Label Text="Label inside border" Margin="8" />
<Button Text="Button inside border" HorizontalAlignment="Left" Margin="8" />
</StackPanel>
</Border>
Also, a Border can be created from code:
var Border = new Alternet.UI.Border();
Border.BorderColor = Alternet.Drawing.Color.DarkGray;
Border.Background = Alternet.Drawing.Brushes.Khaki;

If you want to display a border around your content, you must place the controls within a parent Border element.
