Dock ships with two simple markup extensions that complement Avalonia’s XAML loader. They are distributed in the Dock.MarkupExtension package and can be used independently from the docking system.
LoadExtensionLoadExtension loads a XAML fragment from a URI at runtime and returns the resulting object instance. This is handy when you want to keep small pieces of XAML in separate files without creating data templates.
<TextBlock Text="{markup:Load 'resm:Views/StatusView.axaml?assembly=MyApp'}"/>
The URI is resolved relative to the current IUriContext. Any element type can be loaded. When used as a binding the created object becomes the property value.
ReferenceExtensionReferenceExtension returns an element by name from the current INameScope. It mirrors the behaviour of WPF’s x:Reference markup extension.
<StackPanel>
<Button x:Name="OkButton" Content="OK"/>
<TextBlock Text="{markup:Reference OkButton.Content}"/>
</StackPanel>
The extension searches the nearest name scope for an element called OkButton and returns it. This can be used to bind properties between two elements declared in the same scope.
Both extensions reside in the Avalonia.MarkupExtension namespace and can be imported in XAML using xmlns:markup="clr-namespace:Avalonia.MarkupExtension".
