NameScopePropertyAttribute Class

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


Namespace:  System.Windows.Markup
Assembly:  System.Xaml (in System.Xaml.dll)
[AttributeUsageAttribute(AttributeTargets::Class, AllowMultiple = false, Inherited = true)]
public ref class NameScopePropertyAttribute sealed : public Attribute

The NameScopePropertyAttribute type exposes the following members.

Public methodNameScopePropertyAttribute(String)Initializes a new instance of the NameScopePropertyAttribute class with the specified name.
Public methodNameScopePropertyAttribute(String, Type)Initializes a new instance of the NameScopePropertyAttribute class with the specified name and type.
Public propertyNameGets the name of the property that provides the XAML namescope.
Public propertyTypeGets the owner type of the attached property that provides the XAML namescope support.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Explicit interface implemetationPrivate method_Attribute::GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute::GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute::GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute::InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

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 version 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.

.NET Framework

Supported in: 4, 3.5 SP1, 3.0 SP2

.NET Framework Client Profile

Supported in: 4, 3.5 SP1

Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2

The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
