 The following is an example of how you can set <xref:System.Windows.Controls.DockPanel.Dock%2A?displayProperty=nameWithType> in XAML:

+```xaml
+<DockPanel>
+    <TextBox DockPanel.Dock="Top">Enter text</TextBox>
+</DockPanel>
+```
 
 The usage is somewhat similar to a static property; you always reference the type <xref:System.Windows.Controls.DockPanel> that owns and registers the attached property, rather than referring to any instance specified by name.
