Namespace:  System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation

public class Border : Decorator
<Border>
  Child
</Border>

Content Model: Border can have only one child. To display multiple child elements, you need to place an additional Panel element within the parent Border. You can then place child elements within that Panel element.

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

The following example demonstrates how to create a Border and set properties in code and Extensible Application Markup Language (XAML).

myBorder = new Border();
myBorder.Background = Brushes.LightBlue;
myBorder.BorderBrush = Brushes.Black;
myBorder.BorderThickness = new Thickness(2);
myBorder.CornerRadius = new CornerRadius(45);
myBorder.Padding = new Thickness(25);
<Border Background="LightBlue" 
        BorderBrush="Black" 
        BorderThickness="2" 
        CornerRadius="45" 
        Padding="25">
