NameScopePropertyAttribute NameScopePropertyAttribute NameScopePropertyAttribute NameScopePropertyAttribute Class

Definition

Specifies a property of the associated class that provides the XAML namescope value.

public sealed class NameScopePropertyAttribute : Attribute

Remarks

In a typical object model / application model combination where XAML is used, the classes that are used as a XAML namescope are the classes that are generally used as root elements, or that support a page metaphor. These classes generally implement INameScope and the XAML namescope is created corresponding to the root by typical XAML processing behavior in context of a framework's programming model and application model.

If NameScopePropertyAttribute is used, the XAML namescope property value is expected to be an object that implements INameScope and holds the actual XAML namescope and its behavior.

There are two forms for this attribute: property name only, or type and property. The latter form should be used only for cases where the property that holds the XAML name scope is an attachable member. The attached member technique has the advantage that service classes can implement a XAML namescope concept that can support several different object types. Those object types then do not need to be explicitly related in class inheritance.

In previous versions of the .NET Framework, this class existed in the WPF-specific assembly WindowsBase. In .NET Framework 4, NameScopePropertyAttribute is in the System.Xaml assembly. For more information, see Types Migrated from WPF to System.Xaml.

WPF Usage Notes

In WPF, this attribute is applied to only a single type, DependencyObject. In this case the attributed property is the service class NameScope and its NameScope.NameScope attached property.

Constructors
